Radio Galaxy Zoo Talk
I don't know what in the world this is.
likely overedge?
This is pretty extreme. Looks like a great candidate for giant radio galaxy where all the FIRST emission is gone. No host?.
This looks like a confused field, with NGC4393 in NE, but deserves further scrutiny because there could be an overlapping background source
yes, probably WAT, but more complicated motions, orbits? probably in play
NVSS shows emission to the north and east as well. A very interesting source.
Curious case, one host or two separate sources?
I can't figure out what's going on here. NVSS shows a lot of emission on larger scale.
or two separate sources?
any time you see a nice IR source in the center like this, there is almost certainly a supermassive (billion solar mass) black hole.
i don't think enough details on structure to determine if HyMor. Surprising to find this type of bent source, strong core, no IR.
check out NVSS. My guess is that there's an extremely diffuse lobe opposite the compact bright one.
@JeanTate - why "fading", as opposed to faint, e.g.? do you have something specific in mind?
This is just the inner part of beautiful diffuse source. See FIRST larger field.
mostly one nice source, but at extreme right (west) looks like an additional little compact source.
Looks like nice diffuse double with bright IR near western lobe (right)), instead of centered.
Looks like #overedge to me, but nothing obvious in larger field.
yes, good spot. you can see the full source if you click the "FIRST" or "NVSS" links. we need to figure out how to present these.
Really interesting jet structure. Need to check this one out further. Good spotting!
Definitely a curious asymmetric source worth further study.. Not clear if HyMoRS.
Just looks like a distant compact radio source with no infrared counterpart to me. I don't see anything special.
For a compact source, needs to be "spot on". When you get down to very faint blobs that are all over the place, not worth counting as real.
Beautiful source (double or triple if you want to count nucleus). Does look like a new jet starting.
Yes, good chance of artifact. Look at larger field in NVSS (change size to 0.25deg in link).
Not clear what is going on here. Looks like very asymmetric source, strong emission to lower right (SE) from galaxy, faint to upper left.
Northeast is definitely unusual. There's more extended emission off field towards east.
Yes, pretty source. In the upper left, the compact component is usually called a "hot spot", a place where the jet terminated/dumped power.
pretty cool looking source! anyone else coming across this, you have to look at NVSS.
Indeed, pretty strange. I probably wouldn't emphasize the X-nature, asymmetry is really very nice.
I can't figure this one out either.
Some low level NVSS emission to east (left). Could indicate diffuse emission from old radio galaxy.
Unfortunately, too small to really tell.
Pretty unusual in terms of asymmetry, host being so close to one lobe.
@sisifolibre, I don't think you have the right ID. See the other comments below.
Yes, looks like it hit a brick wall in the south!
Certainly something very intermittent about this, with the knots and then the diffuse emission in NVSS. good source!
Yes, very good catch!
A combination of artefacts and some contamination from neaby sources.
Source to northwest (off edge) is a separate triple source. Source to SE (off edge) - no good evidence to connect it here.
Could be WAT. Not very reliable with such faint emission.
Yes, but really cool! What's the extra emission to the north?
looks like a source with noID to me
Quite unusual. Worth following up.
Needs a careful overlay with NVSS. Might be some diffuse emission to the north?
Hard to tell what to make of the connection between them. Yes, they're not compact. Blend may not be real.
Right, looks like a standard double to me.
NVSS has something extending to the south. So one-sided in fine scale emission, but faint emission, diffuse on other side.
The NVSS extension to the NE could be real. Unfortunately, no other survey to confirm. not covered by SUMSS.
Could be. Unfortunately, too far south for WENSS survey to see if it confirms the NVSS extended structure.
Yes, reminiscent of precessing jets (S-shaped), but quite unusual in detail.
Pretty messy field. If you click NVSS link, it looks like there's more emission here, just too low for contours. ID is unclear to me.
Very strange. I'm not convinced this bright source is the ID. Look to upper left, faint radio+tiny double.SDSS J073947.30+205421.5 z=0.45
Host extended, clearly not star despite SDSS classification. Strange asymmetry
4C42.23, studied with single dishes in late '90s. A beauty.
What a beauty. #overedge . Even doubling size of NVSS field, must be known, need to track down.
This is unusual. Usually, a bright core would have an IR counterpart
Hmm... I'd probably go for #ifrs with a faint WISE nearby. No real confidence that they're related.
Multiple sources, very odd. Needs followup.
Thought I saw this before? Very odd morphology, worth following up.
ID looks like SDSS J125624.74+552825.9, photoz=0.66, about 700kpc double or so.
Very unusual asymmetric source. Can't tell how it was really made.
Pretty wide-angle-tail, probably showing precession of the central black hole.
Beautiful triple.
Thanks. I'll point this out to the software team.
Pretty clear FRII with distortions. Why did SDSS miss this? I sent a message to their help desk.
Hmmm, not clear to me why this is #overedge.
I'm suspicious of the double to the NW. It's sitting on an instrumental artifact, so hard to evaluate.
Yes, this is an instrumental artifact from a very bright source. Click on "FIRST" above to see the larger field and distinct pattern.
I don't see evidence for overedge, so nice distant compact.
Good catch. Looks like a nice giant with a little jet.
Alternatively, just jets that we're seeing the peaks of, which seems a little more likely looking at the FIRST emission
Yes, sort of a hybrid, but a bit confused because it looks like there are two possible IDs - perhaps two superposed sources. Strange.
I agree, Tricky source. I'd vote for @Dolorous Edd's 160909 source below, with spurious compact radio source near N lobe. Good catch!
@ChrisMolloy -- thanks! for your hard work. note, you don't need to spend time classifying #compact objects , just more complicated ones
I'm suspicious about the diffuse patch in the south. Not obvious whether it's there in NVSS, so possibly could be some artifact.
I think the top source is probably just an unrelated very distant radio source, with no IR identification
I agree, a messy triple.
I agree. Very nice large double with strong one-sided jet at base.
What is the source of the proper motion information? Surely not the radio?
Yes, probably same. Separation is about 20" . NVSS beam is 45" across, and there's some extra NVSS flux that pulls the position away.
This is very strange, apparently a bright core (towards the north), but no optical ID and very asymmetric.
Yes, looks like nice probable common envelope optical system. Quite asymmetric,
Not sure what the question is. Looks like a very faint SDSS id.
This is an interesting one. Probably deserves further study.
NVSS makes it look like a single source, but I'd bet on the QSO being separate from small double, no ID.
pretty system!
what do you mean by "hybrid host"? em+abs lines?
I don't really think #hybrid. Defniitely one sided jet, but probably pretty diffuse structure on opposite side as well, not FRII hotspot.
This is a pretty extreme case of a hot-spot dominated source. Without a core, I don't see how to identify the host.
May be something more in NVSS. More likely double source with jet? Worth checking out.
I would have said too close to be a coincidence. But we're looking at so many sources now, that hard to do the statistics of coincidence.
Yes, this is a beauty. Not sure whether previously known. May just be that the inner jets are visible, so currently active, but restarting?
The brightest galaxy near the center of this large #overedge double is SDSS J091251.19+350852.0, z_ph=0.265, so yes, a giant.
Looks like giant. no id, so z=0.5 -->1.06Mpc, z=1 --> 1.4Mpc. See http://umn.edu/~larry/RGZ/ARG0000jzx_over.png Separate source to right.
Nice one! About 800kpc across.
Looks like it could be two sources. Core is in center, but no ID. Quite bright in NVSS.
Nice cluster looking field. Compact ID clear, but is it also the WAT ID? See overlay http://umn.edu/~larry/RGZ/ARG0001gsv_over.png
Hmm, odd looking, and not obviously host?
Yes, quite unusual. I'm unclear whether the compact feature isn't the core and the other lobe missing. But there's no ID on compact.
foreground star, just gets in our way.
Looks like two unrelated radio sources, plus giant diffraction spike from a foreground star.
Cataclysmic binaries are stars. If you click on the SDSS link, you can see that these are galaxies, so it's likely supermassive black hole.
This is a very nice #double jetted source. Whether or not it's a massive one depends on redshift (distance), yet to be determined.
See collection. This looks like a very asymmetric source with the ID in the upper right.
nice combination. we'll probably see it again centered on the #hourglass
For things this faint, I don't think it matters whether you make ID. The accidental rate will be so high that we'll likely have to cut them.
Wow, this is confusing! I wouldn't call these jets. I see two bright components, one compact, one extended, & two faint. No obvious IDs.
Yes, there are artefacts around, but the main bright source in the center is just fine.
Oh, sorry, spoke too soon -- it's the spectrum. I'll take a look!
Not sure what's weird about this. Looks like a standard double radio source with host in the center.
Two jets/plumes, with some wiggles which suggest that perhaps there's a binary black hole in core, in mutual orbit, giving wiggles.
whiteout from extremely bright nearby star.
yes, strange looking SDSS colors. i'd guess two separate.
My guess i host is in the northwest (upper right), and it is a tailed radio galaxy extending southeast with a compact component in tail.
what in the world?? doesn't look like anyone has worked on this?
These are nice indicators of motion through a surrounding medium. Structures like this are usually called "wide angle tails" #wat
I am completely confused. May be two sources. See http://umn.edu/~larry/RGZ/ARG00025v9.jpg . S source is .049, N is part of z=0.26 cluster
These are way too far apart to be a "pair" of black holes, but the two galaxies (click on SDSS to match up field) are likely bound together
yes, and if you click NVSS you can see it's even much bigger than apparent here.
Yes, you'd really want deep observations to try to find a faint core on the proposed ID, otherwise could be random superposition.
Hmm, perhaps #headtail, but ID isn't really at leading edge. We'd need better radio resolution to really tell.
It's offset from the centerline, but sitting on likely radio core. see http://umn.edu/~larry/RGZ/ARG00013hb.jpg
Very curious system. no obvious ids to me. See http://umn.edu/~larry/RGZ/ARG0003gvf.jpg
Yes, looks like two separate sources. Compact to south and extended, quite faint, to the north and off to the east.
The "ID" is actually to the right (West) of the radio source. This could be a #wat with invisible radio core, or a mis-ID.
Most likely ID as below. Could be #wat or some other kind of distortion.
I agree, no ID. Could be a small double.
very pretty. Giant, apparently, 1.1 Mpc, #wat.
Could be #artefact, although it's 1.2mJy. There are three strong sources nearby, so could be sidelobe interference. Strange.
Only candidate ID seems to be SDSS J093655.98+182426.3, in crosshairs at http://umn.edu/~larry/RGZ/ARG0002gc3.jpeg, zph=0.091, looks good.
what a curious field. probably worth trying to figure out if these are related, e.g., part of some supercluster structure.
Looks like another giant! Good catch.
I'd guess three independent sources, although the bottom two could be related. no real way to tell.
Doesn't look over-edge to me, more like nearby sources. These are a mess to figure out!
As you note, FIRST often missing diffuse emission. This is influencing our next generation surveys. Making sure diffuse is better sampled.
Very unusual system. Definitely worth followup.
There are starting to be enough of these not-red-dead that we scientists need to think about how to assemble a well defined sample to study.
Perhaps tiny hint of emission in NVSS to NW? Very nice asymmetric candidate no matter what.
Hmm, Doesn't look like artifact to me . But quite unusual, no ID, one sided jet?
Little bit of a false alarm. The bright long band is the diffraction spike from a distant very bright star... oh well!
Wow, this one's a beauty. ID not clear. Very red object is bright one above. See http://umn.edu/~larry/RGZ/ARG0002fc2comp.jpg
Looks like a single, very asymmetric source to me. Marked for further study.
Looked at NVSS+FIRST+SDSSr; still can't figure it out. Marking for later study.
I have NO idea what this interesting field is.... checking it out.
See http://umn.edu/~larry/RGZ/ARG0000neq.jpg
How in the world did you find that this was over-edge??? I think I've seen it before. Fantastic source.
Perhaps a #WAT, but not a #NAT.
"negative" just occurs randomly. This is likely a very distant, faint IR source.
This is a very pretty wide-angle-tail #WAT radiogalaxy. Compact feature with two thin jets coming out is the IR id. Blobs from jets.
These are artifacts from the presence of this strong source.
Just a very bright IR galaxy. See structure by clicking SDSS
Quite unusual. NVSS shows some diffuse emission around, but not clear what total structure is.
Crazy source! Not clear how many there are. SDSS looks like a cluster at z=0.22 . Worth followup.
I think a better candidate for the ID would be between the two lobes, further to left.
Confusing source. Extra NVSS stuff in FIRST also. See http://umn.edu/~larry/RGZ/ARG0002twj.jpg
Why one-sided since there's no IR to tell about center?
Although there are hints of additional emission in NVSS, I think this is due to faint sources barely visible in FIRST.
Hmm, looks like multiple sources, but no evidence of merger.
Yes, good catch. NVSS shows 4 Jy source about 20minutes away, lots of artifacts.
A beautiful WAT at z=0.138 in poor cluster. Sharp bends. See http://umn.edu/~larry/RGZ/ARG0003qoq.jpg . White contours are marginal X-rays.
Looks like a coincidence. Other spirals in the larger field. I think the #overedge is really multiple sources.
The radio looks like triple, but IR source should be on middle, not bottom component. Check out wider FIRST &NVSS fields. I'm confused!
Very pretty source. Looks like others have commented on it. Check out the SDSS link. Nice cluster of galaxies.
Sadly, it's a star in our own galaxy, blocking the distant object responsible for the radio source.
That's a pretty one.
This is a #triple, with the southern jet off screen. Good catch on the ID. Unusual looking galaxy, unusual color variations, needs study.
This is a star, getting in the way of our radio source!
Check out NVSS. This is a #double with the southern lobe very faint and no jet like the north. also visible nicely in FIRST link also.
Yes, our classifications fail us here. Double either restarted or distorted by relative motion of surrounding medium.
Not sure why this would be called a #plume. Just looks like nice #doublelobe. To me, a #plume would more one-sided from BH.
Definitely nicely warped jets. Probably from an interaction with a surrounding medium in a group or cluster of galaxies.
Hmm, this is a bit unusual, but whether it's a hybrid would probably take higher resolution radio observations.
Wow, this is a beauty. It almost looks like there's another source confusing things there, with the extra component to south of center.
Looks like a cluster of galaxies to me, when you go to SDSS and look at wider field. I haven't checked catalogs yet.
Looks like a nice WAT or distorted double to me.
This is a tricky one. Not sure what it fits into any category nicely.
i'd go for independent.
Cool source. I put it in the "too good to be true" category. Restarting in a new direction? Worth followup.
Yes, this is a little odd, because there's a hot spot in the eastern (left) lobe, but not in west.
Faint radio emission to south of main source. I didn't classify it.
Good catch! see discussion.
Looks like three separate sources here. Top pair, slightly resolved source in middle, and compact one at bottom.
Core + two "lobes" (from jets). Core is the small component in the middle. That's where you'd look for the ID, but there is none in WISE.
I'm baffled by this; the compact source doesn't fit in, as well as the missing emission structure.
Died out. We're seeing lots like this, more than i expected.
Very strange diffuse emission in NVSS. This FIRST source looks like a disconnected double to me, no ID.
Good catch. Source in center, of course, is real.
Bottom not #headtail because ID is in middle, not one end. Cute trio of sources.
Could be just two #compact, unrelated. Small chance that it's actually a #double.
Definitely worth following up. I went to a 1deg field, still couldn't see anything. nothing extra in VLSSr, too low for WENSS, & no SUMSS
Nice find. The best known example like this is Centaurus A, but I don't know if anyone has seen this one before. Thanks!
Beautiful. i'd guess #nat . In galaxy group. No obvious X-rays. Greyscale pix w/NVSS contours, http://umn.edu/~larry/RGZ/ARG0002p2f.jpg
What a great field! Haven't seen @firejuggler in a while, welcome back!
Yes, pretty clear that it's something like a jet which is expanding, disappearing from FIRST still visible in NVSS
Quit curious. To the upper right (NW) the NVSS source does look extended, FIRST looks unresolved there. Don't know what to think.
This is a nice double with IR identification in the middle. Hard for computers to do, so that's why we need you!
Because the two are slightly extended towards each other likely double. Click NVSS also. No obvious ID.
Highly likely it's two sources. Nice triple in middle w/ IR, radio with no IR to right. If they were much closer, I'd be more suspicious
This is due to a bright nearby star. It's called a "diffraction spike" - unavoidable.
from NVSS this looks like a large bent source, possibly #wat
Very unusual one-sided source, even on NVSS.
Not clear this is AGN. It could be a nuclear starburst. Would need other confirming data.
This is pretty simple (at this level of visible detail) #compact source associated with faint IR source. SDSS says "star", so probably QSO.
nice central cluster galaxy.
on the FIRST greyscale, the little tail looks pretty real to me.
Quite unusual one sided.
Hard to say what this is. Would need deeper map at FIRST resolution.
This looks like a #wat to me. Halos don't have any galaxy associated with them, they are MUCH larger, low brightness.
it's a beauty! welcome aboard.
or, one sided-jet
tricky one
could well be. id not clear.
there's probably some interesting strucuture in the northern lobe. would need higher resolution map to tell.
this looks fine to me, along with faint diagonal line=artifact. the NVSS sources off frame to left and right just coincidence, i think
Could be, map really not good enough quality.
I think so.
Quite interesting field. Don't know about central source here. See http://umn.edu/~larry/RGZ/ARG0000myo.jpeg Strange chain of compact srcs.
Looks like a compact source in center, with double to lower right.
The multiple arms, very symmetric, are a pattern of artifacts seen around strong sources.
Check out NVSS. this looks like a nice #wat with no structure visible in FIRST on the right side.
@MEANA this is a small piece of a much larger source that goes offscreen to the south. Click on NVSS below pic, change size to 0.45, and see
This is quite tricky. IR and SDSS source not on the central component, so ID and structure not clear.
Another one of these real odballs.
Nice large QSO SDSS J081605.18+160345.3 at z=1.43, 700 kpc long
Here's my guess. Double, two hotspots, lobes in NVSS, southern compact source background. See http://umn.edu/~larry/RGZ/ARG00001mn.jpg
PLEASE stop using #relic for these. This is a #double. Thanks!
Hourglass is fine. Relic isn't really relevant.
Almost certainly a very large #double. Question is the ID. Possible photoz >0.5 but needs checking.
I withdraw my "cute" comment -- it's a lot more than that!
sorry, i'm not a fan of the "relic" terminology for these.. This is a compact #triple source with #noinfrared counterpart.
Cute idea! Would have to be checked out further to see if it's just random background source.
these are just the brightes spots in the otherwise pretty common triple in NVSS (except it looks like double there because core blended in.
Core looks like small spot to left above. WISE source coincident, no SDSS
This pair of sources isnt' associated with the spectacular tail to North - Owen & I discovered in '76, see http://umn.edu/~larry/RGZ/HT.pdf
Indeed. Sometimes material backflowing to the nucleus bulges out in one direction or another, but I've not seen this shape before.
Yes, that is correct.
Simpler to call it a #double with the faint IR ID in the center.
Yes, click on SDSS link below image and you'll see the very bright galaxy at higher resolution, so it's not blended into one big blob.
Yes, I wasn't trying to highlight ID, just point out connection in east. Better diagram now at http://umn.edu/~larry/RGZ/ARG0003j4t.jpg
Probably, but we are starting to face science problem that at high resolution (like FIRST) we should see twin tails, but don't. Puzzling.
Object below radio is nearby star, not related to radio. IR identifications must be coincident with radio or between two lobes. Thanks!
This is tricky. NVSS looks like #double. But FIRST there are 2 sources which could be a double, but are not because they both have ID.
This is only a piece of the source! Check out NVSS, change the pixels to 900, change size to 0.5deg, and stand in awe!
Just one of those strange coincidences, but worth noting because once in a while there'll be a winner!
Good catch! This is a large #triple, see the NVSS link - large double, with core above smeared out. Jet goes up & right into NVSS lobe.
Doesn't look like #overedge , just unrelated 2nd comp. to lower right (southwest). Apparent bridge between the 2 in NVSS not there in WENSS.
Looks like nice #double. Good catch!!
this is likely #headtail, given how far it extends with the tails close and in parallel in NVSS. Headtails look like #wat at leading edge
Pretty cool! Could be a #wat heavily projected so that it is almost along the line of sight.
Likely good call, but you need SDSS to see. Two galaxies with photom. redshifts around 0.25 . See http://umn.edu/~larry/RGZ/ARG0002og9.jpg
I think ID is in center, SDSS z=0.15, one sided jet. IR in the jet probably accidental.
I've started a new collection with this (new types of radio source). See picture FIRST, NVSS at http://umn.edu/~larry/RGZ/ARG0003j4t.jpg
Don't know how you spotted this! See image at http://umn.edu/~larry/RGZ/ARG0002xex.jpeg Very faint SDSS galaxy at photoz around 0.36
Sorry, not #headtail, it's a #triple, but still a beauty.
Yes, a beauty, going #offedge to north. See FIRST link to larger field.
One of infrared is probably related, and one not. But impossible to choose. Very high radio resolution would be needed to find small core.
These are artifacts, in a hexagonal pattern which is more visible if you click the FIRST link below the image. See "lattice" discussion
Looks like 2 IR sources are blended.
#double and #wat looks right to me
This is crazy! As @antikodon notes with NVSS picture, this is a very large #double. See http://umn.edu/~larry/RGZ/ARG00013o5.jpeg
Could be. But since the ID is on one peak, that's the likely black hole. Instead of jet towards us, could just be a very small jet
This is the southern extremity of a #giant . See the Discussion boards.
This is the top half of of #nat , another "messy" source, whose name I can not now find.
This is a beautiful example of a narrow-angle tail ( #nat ) extending about 3-4 times the length you see here.
I think this may be a triple source with a faint core and no IR component visible
I wouldn't call it X-shaped, probably some precessing jets. But you could be right, needs higher resolution.
That's probably the best bet.
This has a bit unusual brightness distribution for a #wat (a quite subtle ponit) so I would probably classify it as #bent #double
The IR source is actually a blend of two sources as seen in SDSS. See http://umn.edu/~larry/RGZ/ARG0002rbg
I'm suspicious that these two could be part of a #double.
Are these related? Part of a #triple?
I missed the 2nd component.
Confused by overlapping star in IR.
This looks like 2/3 of a #triple.
This is a tricky one. Could be a #wat , but then I'd expect to see some emission directly on the IR source
This is a nice strong double at edge of area mapped by the telescope.. All the little contours are just "noise", not real.
Looks like simple source, #noIR . #relic sources near impossible to identify here, needs X-rays. I would suggest dropping that option.
This looks like simple #double to me, with no IR (or faint) counterpart. #relic sources are very hard to spot and need X-rays to confirm.
This is a slightly resolved, probably #double source, with no IR counterpart. The faint X-shaped features are an artefact.
Very asymmetric double?
Source on left is very unusual. looks like half a double.
Yes, good call.
Yes, that's almost certainly what's happening.
There's a bright source off the left edge that is creating likely spurious patches along a line tilting slightly up.
Very nice! Top source separate. Four at bottom are one source. 2nd from top is the black hole; southern jet has bright patch and bright end
Looks like there is probably a faint infrared source behind the central component. Not the most striking but worth checking more.
Yes, this is a very unusual field. Definitely worth following up on.
Yes, IR near the middle is a good match. If it's on a peak, then that peak is a separate source. If it's nowhere near middle, questionable.
These may be jets seen at low resolution, so you don't see long linear structure. Here, the black hole should be in middle but isn't seen.
This is almost certainly a nice #doublelobe source with an IR counterpart in the center, smeared together with an additional IR galaxy.
I haven't seen ANY examples of relics yet. We know about them from dedicated studies of clusters, so want to be on lookout.
As co-author on the '76 definition paper 😉 i think this is "wide angle tail"; w/ stream to right also coming from BH, but missing a patch
This is really an oddball. Would love to get higher resolution images in radio. Could be random superposition or something quite exotic.
Whoops! I messed this one up. Only got one of the two components.
This is a really tricky one. I think it's a triple, with the central radio component coincident with IR galaxy. But then IR on North radio?
Hmmm, reconsidering my previous comment. There isn't any IR under the southern radio, so this could be a #plume, or two independent sources
Wow! This one is pretty complicated in its radio structure. I'd love to see it at higher resolution, so we could see the details!
Looks like two independent sources to me, just very close together, because I seen an IR component on the southern radio contours as well.
There is an extended IR structure around the southern radio source. I didn't mark an ID here, but perhaps should have.
I probably should have IR classification here, but couldn't see it because of radio contours until I said "finish" & then couldn't go back.
I marked an IR identification, but it is faint and possibly blended, so may not be real.
Perhaps I was moving too quickly, but I was only able to click on one source, then "no ir", but it wouldn't let me "mark another."
Technical problem here. Image in center has no contours.
Badly blended IR.
For northern source, I gave it an IR component. However, it is faint enough to be in confusion. This can prob. get removed in post-proc.
IR blended beyond recognition.
Again, IR so burned out that any reasonable classification is not possible.
IR is blended at level to not be useful.
IR is badly blended.
In the top source (middle of frame) the contours overlap IR source, but I didn't click it because it is offset.
I marked the source in the middle as a double, because of low level radio (blue) emission, but they could be two separate sources.
IR has multiple objects blended together, so can't select the correct one.
This is a nice bright radio source, but there are no contours on it. i thought they might just be invisible, so i clicked, but nothing lit.
there were more radio contours, but it never took me to a screen where i could select mark another contour.
I clicked no infrared here, but re-looking at it, there is a barely detectable infrared source at the peak of the radio contours.
I don't know what in the world this is.
likely overedge?
This is pretty extreme. Looks like a great candidate for giant radio galaxy where all the FIRST emission is gone. No host?.
This looks like a confused field, with NGC4393 in NE, but deserves further scrutiny because there could be an overlapping background source
yes, probably WAT, but more complicated motions, orbits? probably in play
NVSS shows emission to the north and east as well. A very interesting source.
Curious case, one host or two separate sources?
I can't figure out what's going on here. NVSS shows a lot of emission on larger scale.
or two separate sources?
any time you see a nice IR source in the center like this, there is almost certainly a supermassive (billion solar mass) black hole.
i don't think enough details on structure to determine if HyMor. Surprising to find this type of bent source, strong core, no IR.
check out NVSS. My guess is that there's an extremely diffuse lobe opposite the compact bright one.
@JeanTate - why "fading", as opposed to faint, e.g.? do you have something specific in mind?
This is just the inner part of beautiful diffuse source. See FIRST larger field.
mostly one nice source, but at extreme right (west) looks like an additional little compact source.
Looks like nice diffuse double with bright IR near western lobe (right)), instead of centered.
Looks like #overedge to me, but nothing obvious in larger field.
yes, good spot. you can see the full source if you click the "FIRST" or "NVSS" links. we need to figure out how to present these.
Really interesting jet structure. Need to check this one out further. Good spotting!
Definitely a curious asymmetric source worth further study.. Not clear if HyMoRS.
Just looks like a distant compact radio source with no infrared counterpart to me. I don't see anything special.
For a compact source, needs to be "spot on". When you get down to very faint blobs that are all over the place, not worth counting as real.
Beautiful source (double or triple if you want to count nucleus). Does look like a new jet starting.
Yes, good chance of artifact. Look at larger field in NVSS (change size to 0.25deg in link).
Not clear what is going on here. Looks like very asymmetric source, strong emission to lower right (SE) from galaxy, faint to upper left.
Northeast is definitely unusual. There's more extended emission off field towards east.
Yes, pretty source. In the upper left, the compact component is usually called a "hot spot", a place where the jet terminated/dumped power.
pretty cool looking source! anyone else coming across this, you have to look at NVSS.
Indeed, pretty strange. I probably wouldn't emphasize the X-nature, asymmetry is really very nice.
I can't figure this one out either.
Some low level NVSS emission to east (left). Could indicate diffuse emission from old radio galaxy.
Unfortunately, too small to really tell.
Pretty unusual in terms of asymmetry, host being so close to one lobe.
@sisifolibre, I don't think you have the right ID. See the other comments below.
Yes, looks like it hit a brick wall in the south!
Certainly something very intermittent about this, with the knots and then the diffuse emission in NVSS. good source!
Yes, very good catch!
A combination of artefacts and some contamination from neaby sources.
Source to northwest (off edge) is a separate triple source. Source to SE (off edge) - no good evidence to connect it here.
Could be WAT. Not very reliable with such faint emission.
Yes, but really cool! What's the extra emission to the north?
looks like a source with noID to me
Quite unusual. Worth following up.
Needs a careful overlay with NVSS. Might be some diffuse emission to the north?
Hard to tell what to make of the connection between them. Yes, they're not compact. Blend may not be real.
Right, looks like a standard double to me.
NVSS has something extending to the south. So one-sided in fine scale emission, but faint emission, diffuse on other side.
The NVSS extension to the NE could be real. Unfortunately, no other survey to confirm. not covered by SUMSS.
Could be. Unfortunately, too far south for WENSS survey to see if it confirms the NVSS extended structure.
Yes, reminiscent of precessing jets (S-shaped), but quite unusual in detail.
Pretty messy field. If you click NVSS link, it looks like there's more emission here, just too low for contours. ID is unclear to me.
Very strange. I'm not convinced this bright source is the ID. Look to upper left, faint radio+tiny double.SDSS J073947.30+205421.5 z=0.45
Host extended, clearly not star despite SDSS classification. Strange asymmetry
4C42.23, studied with single dishes in late '90s. A beauty.
What a beauty. #overedge . Even doubling size of NVSS field, must be known, need to track down.
This is unusual. Usually, a bright core would have an IR counterpart
Hmm... I'd probably go for #ifrs with a faint WISE nearby. No real confidence that they're related.
Multiple sources, very odd. Needs followup.
Thought I saw this before? Very odd morphology, worth following up.
ID looks like SDSS J125624.74+552825.9, photoz=0.66, about 700kpc double or so.
Very unusual asymmetric source. Can't tell how it was really made.
Pretty wide-angle-tail, probably showing precession of the central black hole.
Beautiful triple.
Thanks. I'll point this out to the software team.
Pretty clear FRII with distortions. Why did SDSS miss this? I sent a message to their help desk.
Hmmm, not clear to me why this is #overedge.
I'm suspicious of the double to the NW. It's sitting on an instrumental artifact, so hard to evaluate.
Yes, this is an instrumental artifact from a very bright source. Click on "FIRST" above to see the larger field and distinct pattern.
I don't see evidence for overedge, so nice distant compact.
Good catch. Looks like a nice giant with a little jet.
Alternatively, just jets that we're seeing the peaks of, which seems a little more likely looking at the FIRST emission
Yes, sort of a hybrid, but a bit confused because it looks like there are two possible IDs - perhaps two superposed sources. Strange.
I agree, Tricky source. I'd vote for @Dolorous Edd's 160909 source below, with spurious compact radio source near N lobe. Good catch!
@ChrisMolloy -- thanks! for your hard work. note, you don't need to spend time classifying #compact objects , just more complicated ones
I'm suspicious about the diffuse patch in the south. Not obvious whether it's there in NVSS, so possibly could be some artifact.
I think the top source is probably just an unrelated very distant radio source, with no IR identification
I agree, a messy triple.
I agree. Very nice large double with strong one-sided jet at base.
What is the source of the proper motion information? Surely not the radio?
Yes, probably same. Separation is about 20" . NVSS beam is 45" across, and there's some extra NVSS flux that pulls the position away.
This is very strange, apparently a bright core (towards the north), but no optical ID and very asymmetric.
Yes, looks like nice probable common envelope optical system. Quite asymmetric,
Not sure what the question is. Looks like a very faint SDSS id.
This is an interesting one. Probably deserves further study.
NVSS makes it look like a single source, but I'd bet on the QSO being separate from small double, no ID.
pretty system!
what do you mean by "hybrid host"? em+abs lines?
I don't really think #hybrid. Defniitely one sided jet, but probably pretty diffuse structure on opposite side as well, not FRII hotspot.
This is a pretty extreme case of a hot-spot dominated source. Without a core, I don't see how to identify the host.
May be something more in NVSS. More likely double source with jet? Worth checking out.
I would have said too close to be a coincidence. But we're looking at so many sources now, that hard to do the statistics of coincidence.
Yes, this is a beauty. Not sure whether previously known. May just be that the inner jets are visible, so currently active, but restarting?
The brightest galaxy near the center of this large #overedge double is SDSS J091251.19+350852.0, z_ph=0.265, so yes, a giant.
Looks like giant. no id, so z=0.5 -->1.06Mpc, z=1 --> 1.4Mpc. See http://umn.edu/~larry/RGZ/ARG0000jzx_over.png
Separate source to right.
Nice one! About 800kpc across.
Looks like it could be two sources. Core is in center, but no ID. Quite bright in NVSS.
Nice cluster looking field. Compact ID clear, but is it also the WAT ID?
See overlay http://umn.edu/~larry/RGZ/ARG0001gsv_over.png
Hmm, odd looking, and not obviously host?
Yes, quite unusual. I'm unclear whether the compact feature isn't the core and the other lobe missing. But there's no ID on compact.
foreground star, just gets in our way.
Looks like two unrelated radio sources, plus giant diffraction spike from a foreground star.
Cataclysmic binaries are stars. If you click on the SDSS link, you can see that these are galaxies, so it's likely supermassive black hole.
This is a very nice #double jetted source. Whether or not it's a massive one depends on redshift (distance), yet to be determined.
See collection. This looks like a very asymmetric source with the ID in the upper right.
nice combination. we'll probably see it again centered on the #hourglass
For things this faint, I don't think it matters whether you make ID. The accidental rate will be so high that we'll likely have to cut them.
Wow, this is confusing! I wouldn't call these jets. I see two bright components, one compact, one extended, & two faint. No obvious IDs.
Yes, there are artefacts around, but the main bright source in the center is just fine.
Oh, sorry, spoke too soon -- it's the spectrum. I'll take a look!
Not sure what's weird about this. Looks like a standard double radio source with host in the center.
Two jets/plumes, with some wiggles which suggest that perhaps there's a binary black hole in core, in mutual orbit, giving wiggles.
whiteout from extremely bright nearby star.
yes, strange looking SDSS colors. i'd guess two separate.
My guess i host is in the northwest (upper right), and it is a tailed radio galaxy extending southeast with a compact component in tail.
what in the world?? doesn't look like anyone has worked on this?
These are nice indicators of motion through a surrounding medium. Structures like this are usually called "wide angle tails" #wat
I am completely confused. May be two sources. See http://umn.edu/~larry/RGZ/ARG00025v9.jpg . S source is .049, N is part of z=0.26 cluster
These are way too far apart to be a "pair" of black holes, but the two galaxies (click on SDSS to match up field) are likely bound together
yes, and if you click NVSS you can see it's even much bigger than apparent here.
Yes, you'd really want deep observations to try to find a faint core on the proposed ID, otherwise could be random superposition.
Hmm, perhaps #headtail, but ID isn't really at leading edge. We'd need better radio resolution to really tell.
It's offset from the centerline, but sitting on likely radio core. see http://umn.edu/~larry/RGZ/ARG00013hb.jpg
Very curious system. no obvious ids to me. See http://umn.edu/~larry/RGZ/ARG0003gvf.jpg
Yes, looks like two separate sources. Compact to south and extended, quite faint, to the north and off to the east.
The "ID" is actually to the right (West) of the radio source. This could be a #wat with invisible radio core, or a mis-ID.
Most likely ID as below. Could be #wat or some other kind of distortion.
I agree, no ID. Could be a small double.
very pretty. Giant, apparently, 1.1 Mpc, #wat.
Could be #artefact, although it's 1.2mJy. There are three strong sources nearby, so could be sidelobe interference. Strange.
Only candidate ID seems to be SDSS J093655.98+182426.3, in crosshairs at http://umn.edu/~larry/RGZ/ARG0002gc3.jpeg, zph=0.091, looks good.
what a curious field. probably worth trying to figure out if these are related, e.g., part of some supercluster structure.
Looks like another giant! Good catch.
I'd guess three independent sources, although the bottom two could be related. no real way to tell.
Doesn't look over-edge to me, more like nearby sources. These are a mess to figure out!
As you note, FIRST often missing diffuse emission. This is influencing our next generation surveys. Making sure diffuse is better sampled.
Very unusual system. Definitely worth followup.
There are starting to be enough of these not-red-dead that we scientists need to think about how to assemble a well defined sample to study.
Perhaps tiny hint of emission in NVSS to NW? Very nice asymmetric candidate no matter what.
Hmm, Doesn't look like artifact to me . But quite unusual, no ID, one sided jet?
Little bit of a false alarm. The bright long band is the diffraction spike from a distant very bright star... oh well!
Wow, this one's a beauty. ID not clear. Very red object is bright one above. See http://umn.edu/~larry/RGZ/ARG0002fc2comp.jpg
Looks like a single, very asymmetric source to me. Marked for further study.
Looked at NVSS+FIRST+SDSSr; still can't figure it out. Marking for later study.
I have NO idea what this interesting field is.... checking it out.
See http://umn.edu/~larry/RGZ/ARG0000neq.jpg
How in the world did you find that this was over-edge??? I think I've seen it before. Fantastic source.
Perhaps a #WAT, but not a #NAT.
"negative" just occurs randomly. This is likely a very distant, faint IR source.
This is a very pretty wide-angle-tail #WAT radiogalaxy. Compact feature with two thin jets coming out is the IR id. Blobs from jets.
These are artifacts from the presence of this strong source.
Just a very bright IR galaxy. See structure by clicking SDSS
Quite unusual. NVSS shows some diffuse emission around, but not clear what total structure is.
Crazy source! Not clear how many there are. SDSS looks like a cluster at z=0.22 . Worth followup.
I think a better candidate for the ID would be between the two lobes, further to left.
Confusing source. Extra NVSS stuff in FIRST also. See http://umn.edu/~larry/RGZ/ARG0002twj.jpg
Why one-sided since there's no IR to tell about center?
Although there are hints of additional emission in NVSS, I think this is due to faint sources barely visible in FIRST.
Hmm, looks like multiple sources, but no evidence of merger.
Yes, good catch. NVSS shows 4 Jy source about 20minutes away, lots of artifacts.
A beautiful WAT at z=0.138 in poor cluster. Sharp bends. See http://umn.edu/~larry/RGZ/ARG0003qoq.jpg . White contours are marginal X-rays.
Looks like a coincidence. Other spirals in the larger field. I think the #overedge is really multiple sources.
The radio looks like triple, but IR source should be on middle, not bottom component. Check out wider FIRST &NVSS fields. I'm confused!
Very pretty source. Looks like others have commented on it. Check out the SDSS link. Nice cluster of galaxies.
Sadly, it's a star in our own galaxy, blocking the distant object responsible for the radio source.
That's a pretty one.
This is a #triple, with the southern jet off screen. Good catch on the ID. Unusual looking galaxy, unusual color variations, needs study.
This is a star, getting in the way of our radio source!
Check out NVSS. This is a #double with the southern lobe very faint and no jet like the north. also visible nicely in FIRST link also.
Yes, our classifications fail us here. Double either restarted or distorted by relative motion of surrounding medium.
Not sure why this would be called a #plume. Just looks like nice #doublelobe. To me, a #plume would more one-sided from BH.
Definitely nicely warped jets. Probably from an interaction with a surrounding medium in a group or cluster of galaxies.
Hmm, this is a bit unusual, but whether it's a hybrid would probably take higher resolution radio observations.
Wow, this is a beauty. It almost looks like there's another source confusing things there, with the extra component to south of center.
Looks like a cluster of galaxies to me, when you go to SDSS and look at wider field. I haven't checked catalogs yet.
Looks like a nice WAT or distorted double to me.
This is a tricky one. Not sure what it fits into any category nicely.
i'd go for independent.
Cool source. I put it in the "too good to be true" category. Restarting in a new direction? Worth followup.
Yes, this is a little odd, because there's a hot spot in the eastern (left) lobe, but not in west.
Faint radio emission to south of main source. I didn't classify it.
Good catch! see discussion.
Looks like three separate sources here. Top pair, slightly resolved source in middle, and compact one at bottom.
Core + two "lobes" (from jets). Core is the small component in the middle. That's where you'd look for the ID, but there is none in WISE.
I'm baffled by this; the compact source doesn't fit in, as well as the missing emission structure.
Died out. We're seeing lots like this, more than i expected.
Very strange diffuse emission in NVSS. This FIRST source looks like a disconnected double to me, no ID.
Good catch. Source in center, of course, is real.
Bottom not #headtail because ID is in middle, not one end.
Cute trio of sources.
Could be just two #compact, unrelated. Small chance that it's actually a #double.
Definitely worth following up. I went to a 1deg field, still couldn't see anything. nothing extra in VLSSr, too low for WENSS, & no SUMSS
Nice find. The best known example like this is Centaurus A, but I don't know if anyone has seen this one before. Thanks!
Beautiful. i'd guess #nat . In galaxy group. No obvious X-rays. Greyscale pix w/NVSS contours, http://umn.edu/~larry/RGZ/ARG0002p2f.jpg
What a great field! Haven't seen @firejuggler in a while, welcome back!
Yes, pretty clear that it's something like a jet which is expanding, disappearing from FIRST still visible in NVSS
Quit curious. To the upper right (NW) the NVSS source does look extended, FIRST looks unresolved there. Don't know what to think.
This is a nice double with IR identification in the middle. Hard for computers to do, so that's why we need you!
Because the two are slightly extended towards each other likely double. Click NVSS also. No obvious ID.
Highly likely it's two sources. Nice triple in middle w/ IR, radio with no IR to right. If they were much closer, I'd be more suspicious
This is due to a bright nearby star. It's called a "diffraction spike" - unavoidable.
from NVSS this looks like a large bent source, possibly #wat
Very unusual one-sided source, even on NVSS.
Not clear this is AGN. It could be a nuclear starburst. Would need other confirming data.
This is pretty simple (at this level of visible detail) #compact source associated with faint IR source. SDSS says "star", so probably QSO.
nice central cluster galaxy.
on the FIRST greyscale, the little tail looks pretty real to me.
Quite unusual one sided.
Hard to say what this is. Would need deeper map at FIRST resolution.
This looks like a #wat to me. Halos don't have any galaxy associated with them, they are MUCH larger, low brightness.
it's a beauty! welcome aboard.
or, one sided-jet
tricky one
could well be. id not clear.
there's probably some interesting strucuture in the northern lobe. would need higher resolution map to tell.
this looks fine to me, along with faint diagonal line=artifact. the NVSS sources off frame to left and right just coincidence, i think
Could be, map really not good enough quality.
I think so.
Quite interesting field. Don't know about central source here.
See http://umn.edu/~larry/RGZ/ARG0000myo.jpeg
Strange chain of compact srcs.
Looks like a compact source in center, with double to lower right.
The multiple arms, very symmetric, are a pattern of artifacts seen around strong sources.
Check out NVSS. this looks like a nice #wat with no structure visible in FIRST on the right side.
@MEANA this is a small piece of a much larger source that goes offscreen to the south. Click on NVSS below pic, change size to 0.45, and see
This is quite tricky. IR and SDSS source not on the central component, so ID and structure not clear.
Another one of these real odballs.
Nice large QSO SDSS J081605.18+160345.3 at z=1.43, 700 kpc long
Here's my guess. Double, two hotspots, lobes in NVSS, southern compact source background. See http://umn.edu/~larry/RGZ/ARG00001mn.jpg
PLEASE stop using #relic for these. This is a #double. Thanks!
Hourglass is fine. Relic isn't really relevant.
Almost certainly a very large #double. Question is the ID. Possible photoz >0.5 but needs checking.
I withdraw my "cute" comment -- it's a lot more than that!
sorry, i'm not a fan of the "relic" terminology for these.. This is a compact #triple source with #noinfrared counterpart.
Cute idea! Would have to be checked out further to see if it's just random background source.
these are just the brightes spots in the otherwise pretty common triple in NVSS (except it looks like double there because core blended in.
Core looks like small spot to left above. WISE source coincident, no SDSS
This pair of sources isnt' associated with the spectacular tail to North - Owen & I discovered in '76, see http://umn.edu/~larry/RGZ/HT.pdf
Indeed. Sometimes material backflowing to the nucleus bulges out in one direction or another, but I've not seen this shape before.
Yes, that is correct.
Simpler to call it a #double with the faint IR ID in the center.
Yes, click on SDSS link below image and you'll see the very bright galaxy at higher resolution, so it's not blended into one big blob.
Yes, I wasn't trying to highlight ID, just point out connection in east. Better diagram now at http://umn.edu/~larry/RGZ/ARG0003j4t.jpg
Probably, but we are starting to face science problem that at high resolution (like FIRST) we should see twin tails, but don't. Puzzling.
Object below radio is nearby star, not related to radio. IR identifications must be coincident with radio or between two lobes. Thanks!
This is tricky. NVSS looks like #double. But FIRST there are 2 sources which could be a double, but are not because they both have ID.
This is only a piece of the source! Check out NVSS, change the pixels to 900, change size to 0.5deg, and
stand in awe!
Just one of those strange coincidences, but worth noting because once in a while there'll be a winner!
Good catch! This is a large #triple, see the NVSS link - large double, with core above smeared out. Jet goes up & right into NVSS lobe.
Doesn't look like #overedge , just unrelated 2nd comp. to lower right (southwest). Apparent bridge between the 2 in NVSS not there in WENSS.
Looks like nice #double. Good catch!!
this is likely #headtail, given how far it extends with the tails close and in parallel in NVSS. Headtails look like #wat at leading edge
Pretty cool! Could be a #wat heavily projected so that it is almost along the line of sight.
Likely good call, but you need SDSS to see. Two galaxies with photom. redshifts around 0.25 . See http://umn.edu/~larry/RGZ/ARG0002og9.jpg
I think ID is in center, SDSS z=0.15, one sided jet. IR in the jet probably accidental.
I've started a new collection with this (new types of radio source). See picture FIRST, NVSS at http://umn.edu/~larry/RGZ/ARG0003j4t.jpg
Don't know how you spotted this! See image at http://umn.edu/~larry/RGZ/ARG0002xex.jpeg
Very faint SDSS galaxy at photoz around 0.36
Sorry, not #headtail, it's a #triple, but still a beauty.
Yes, a beauty, going #offedge to north. See FIRST link to larger field.
One of infrared is probably related, and one not. But impossible to choose. Very high radio resolution would be needed to find small core.
These are artifacts, in a hexagonal pattern which is more visible if you click the FIRST link below the image. See "lattice" discussion
Looks like 2 IR sources are blended.
#double and #wat looks right to me
This is crazy! As @antikodon notes with NVSS picture, this is a very large #double. See http://umn.edu/~larry/RGZ/ARG00013o5.jpeg
Could be. But since the ID is on one peak, that's the likely black hole. Instead of jet towards us, could just be a very small jet
This is the southern extremity of a #giant . See the Discussion boards.
This is the top half of of #nat , another "messy" source, whose name I can not now find.
This is a beautiful example of a narrow-angle tail ( #nat ) extending about 3-4 times the length you see here.
I think this may be a triple source with a faint core and no IR component visible
I wouldn't call it X-shaped, probably some precessing jets. But you could be right, needs higher resolution.
That's probably the best bet.
This has a bit unusual brightness distribution for a #wat (a quite subtle ponit) so I would probably classify it as #bent #double
The IR source is actually a blend of two sources as seen in SDSS. See http://umn.edu/~larry/RGZ/ARG0002rbg
I'm suspicious that these two could be part of a #double.
Are these related? Part of a #triple?
I missed the 2nd component.
Confused by overlapping star in IR.
This looks like 2/3 of a #triple.
This is a tricky one. Could be a #wat , but then I'd expect to see some emission directly on the IR source
This is a nice strong double at edge of area mapped by the telescope.. All the little contours are just "noise", not real.
Looks like simple source, #noIR . #relic sources near impossible to identify here, needs X-rays. I would suggest dropping that option.
This looks like simple #double to me, with no IR (or faint) counterpart. #relic sources are very hard to spot and need X-rays to confirm.
This is a slightly resolved, probably #double source, with no IR counterpart. The faint X-shaped features are an artefact.
Very asymmetric double?
Source on left is very unusual. looks like half a double.
Yes, good call.
Yes, that's almost certainly what's happening.
There's a bright source off the left edge that is creating likely spurious patches along a line tilting slightly up.
Very nice! Top source separate. Four at bottom are one source. 2nd from top is the black hole; southern jet has bright patch and bright end
Looks like there is probably a faint infrared source behind the central component. Not the most striking but worth checking more.
Yes, this is a very unusual field. Definitely worth following up on.
Yes, IR near the middle is a good match. If it's on a peak, then that peak is a separate source. If it's nowhere near middle, questionable.
These may be jets seen at low resolution, so you don't see long linear structure. Here, the black hole should be in middle but isn't seen.
This is almost certainly a nice #doublelobe source with an IR counterpart in the center, smeared together with an additional IR galaxy.
I haven't seen ANY examples of relics yet. We know about them from dedicated studies of clusters, so want to be on lookout.
As co-author on the '76 definition paper 😉 i think this is "wide angle tail"; w/ stream to right also coming from BH, but missing a patch
This is really an oddball. Would love to get higher resolution images in radio. Could be random superposition or something quite exotic.
Whoops! I messed this one up. Only got one of the two components.
This is a really tricky one. I think it's a triple, with the central radio component coincident with IR galaxy. But then IR on North radio?
Hmmm, reconsidering my previous comment. There isn't any IR under the southern radio, so this could be a #plume, or two independent sources
Wow! This one is pretty complicated in its radio structure. I'd love to see it at higher resolution, so we could see the details!
Looks like two independent sources to me, just very close together, because I seen an IR component on the southern radio contours as well.
There is an extended IR structure around the southern radio source. I didn't mark an ID here, but perhaps should have.
I probably should have IR classification here, but couldn't see it because of radio contours until I said "finish" & then couldn't go back.
I marked an IR identification, but it is faint and possibly blended, so may not be real.
Perhaps I was moving too quickly, but I was only able to click on one source, then "no ir", but it wouldn't let me "mark another."
Technical problem here. Image in center has no contours.
Badly blended IR.
For northern source, I gave it an IR component. However, it is faint enough to be in confusion. This can prob. get removed in post-proc.
IR blended beyond recognition.
Again, IR so burned out that any reasonable classification is not possible.
IR is blended at level to not be useful.
IR is badly blended.
In the top source (middle of frame) the contours overlap IR source, but I didn't click it because it is offset.
I marked the source in the middle as a double, because of low level radio (blue) emission, but they could be two separate sources.
IR has multiple objects blended together, so can't select the correct one.
This is a nice bright radio source, but there are no contours on it. i thought they might just be invisible, so i clicked, but nothing lit.
there were more radio contours, but it never took me to a screen where i could select mark another contour.
I clicked no infrared here, but re-looking at it, there is a barely detectable infrared source at the peak of the radio contours.
