Radio Galaxy Zoo Talk
then match it to its host in the background. The reason we show you 2 images is cos you only see the galaxy in IR but the jets in radio
The colours are false colours. The main task here is to identify the radio galaxy which is the bean-shaped radio thing in the centre
It's a galaxy with X-shaped radio jets.
host is likely behind the star 😦
Difficult to say if it's a compact or extended radio source
Hi @Sztanyi, The radio image appears to be severely affected by imaging #artefacts in the north-south direction
I think this is more a #restarted rather than a #hybrid
yes, it does look like a #triple. also #bent
tough to tell without further follow-up observations.
we got photobombed by a foreground star. the star is from our own galaxy
yes that is correct
This is a #bent source
looks like just a #bent source rather than a #hybrid
got photobombed by a foreground star but if you click on the FIRST link above, you would see that we are only seeing 1 lobe of an #overedge
yes, could be a #bent #double
could be but will require further observations to confirm. the likelihood of source confusion may be high in this field
This is officially known as a "double-double" source. So you are seeing 2 episodes of activity in this radio AGN.
yeah, agree with Dolorous_Edd, the hotspot needs to be further offset to one side
oops, correct link here: https://apod.nasa.gov/apod/ap110413.html
take heart that 0.6 Mpc is still very big: cf CenA http://www.scienceimage.csiro.au/library/technology/i/10850/the-centaurus-a-galaxy/
Yes, there is some possibility of asymmetric hotspots. Alternatively, this could be a coincidence with a more distant source.
Sorry @happy2. short answer is you can't. But it'd be great if you can click the Discuss button and make a #star comment. Thanks 😃
likely a confused source with multiple projected hosts
Since the galaxy is undetected in WISE (IR), this is likely a high redshift source
could be or there could be multiple overlapping sources. spectral indices would be helpful
looks like 2 radio galaxies here: a #compact and a #wat which is also #overedge
yes, this is 2 components of a 3-component radio galaxy that is #overedge and extends to the left of this subject
Yes, the radio emission is certainly originating from the central supermassive black hole
could also be 2 separate sources....
@explorer15, what is additional in this image?
I don't think that I see any host in the WISE image so it's an #IFRS
yes, looks like an #overedge source
agree that this is an #artefact
Good work! Looks restarted
by two-page, I think you mean double-lobe right ? 😃
very interesting. I wonder how many radio galaxies are confused here...
I think that this is the host: http://skyserver.sdss.org/dr12/en/tools/explore/Summary.aspx?id=1237654879113838631
If you click on the "FIRST" link above, you'll see that this is part of a larger radio galaxy that can be classed as #overedge
The host galaxy of this sources is so distant into the Early Universe that the WISE IR image is not sensitive enough to see it.
I think that this is a single AGN but there is a small probability that it might be 2
Brilliant! Sometimes X does mark the spot 😃
Yes, it looks like a merger but the spiral structure is not pronounced so I'd just tag this as a #merger
a nearby galaxy SDSS J171425.79+415622.1 with core and jet emission
Hi @tiovitolan, what is a #what? do you mean #wat?
radio sources (south east & west) probably belong to a background galaxy. The compact source comes from the core of NGC3190
good spotting! well done!
#overedge host likely to be http://skyserver.sdss.org/dr12/en/tools/explore/Summary.aspx?id=1237662262703686303
This is an #overedge #bent radio galaxy from a nearby elliptical galaxy. Check out SDSS's view by clicking the SDSS URL above
I think the host galaxy is at z~0.43 SDSS J112802.44+323046.5 so unlikely to be cosmic ray or asteroid...
Looks like 2 separate hosts in this subject: 1 compact & 1 hourglass. I'd probably tag this with #artefact as well.
brilliant nearby galaxy! previously catalogued #giant
My hunch would be probably a #compact source. Reason is because the 2 lobes usually have similar brightnesses unless it's HyMoRS
The radio image is quite noisy and confusing with a fair amount of #artefacts. I suspect that they are overlapping sources.
I reckon that this could be a very distance #IFRS galaxy hosting a #doublelobe
perhaps a candidate nat. image is quite noisy so will need further verification.
perhaps. further observations (deeper, multifrequency) will be required to figure out if it's truly S-shaped or precessing.
possibly. thanks @sisifolibre
I think this is just a #compact source
or 1 WAT and 1 one-sided jet?
it could be a pair of #WATs
i reckon #corejet
or there is a single radio galaxy in the centre and another to the west. #bhgroup
This subject is complex. It could be confusion from a pair of radio galaxies + another radio galaxy to the west (ie group of 3)
the ir object in the top-left corner is a foreground star from our own galaxy
yeah, either 1) #overedge; or 2)SW component is a #compact+ #IFRS centre
This is not a jet in SDSS but a compact group of galaxies
@explorer15, this is an artefact in the IR image
suspect that the white dots in the IR image are due to saturated/bad pixels
yes, please ignore the white line. probably just a boundary between IR fields
You can only "see" black holes when they are actively feeding on material 😉
FWIW I suspect that the host galaxy is between the 2 radio lobes.
The "big" IR source is SDSS J131858.56+161858.2. You can see it by clicking the SDSS link above
perhaps. this subject does contain a fair bit of processing #artefacts so it can go either way
Wow, this is fascinating. Either this is #bent source is associated with a #IFRS or it's only bent on one-side & hosted by SDSS J092644.19+030919.7
Welcome @tomhinde! Yes, I think the upper radio source may be associated with the galaxy that is overlaps slightly with at its southern tip
yeah it looks like it 😃
Looks a little #bent too
this does look like a single #doublelobed
You need to figure out distance first. Mpc=megaparsec. Here is the wiki link to Parsecs: https://en.wikipedia.org/wiki/Parsec
yeah if you slid to the radio-only image, there are lots of artefacts leftover so you're right, I reckon that there may only be 1 source
more blue than green i reckon.....
@indaba: no, I don't think that the galaxies are colliding/merging
yep or possibly #artefact
radio lenses are very rare so it's unlikely but this may be a very distant source
looks like it also perhaps #onesided
I agree. It has got strong OIII but it's clearly not strong enough to make the entire galaxy look green
this is a pair of #bent jets. for eg if the host is falling into a denser environment, the jets can get bent.
Yes, I agree with @Dolorous Edd. I cannot see any spiral arms from the host galaxy.
yeah a somewhat noisy radio image too...
Hi @DanTolle, the small spots are processing #artefacts
#overedge interesting find!
It's a late type host galaxy but as the spiral arms are not visible, I don't think that Dr Mao would consider this to be a SDRAGN
Hi @bazzle94, if you marked all the radio emission as a bent V-shaped jet coming from the one host then you got it right.
yes, this looks like a set of #doublelobes
The B3 object was identified from a radio survey & either emanates from the QSO or is a background obj (cf Ref from NED)
More Details : http://arxiv.org/abs/astro-ph/9905116
Welcome to cosmology 😃 Wiki has a simple explanation: http://en.wikipedia.org/wiki/Angular_diameter_distance
yes, it does look like an #hourglass
Beautiful example of a #wat. Great find!
yes it's green as it has very strong OIII emission
seems #bent too
could be a #plume or maybe even a #wat?
You are right. This object is too far south for the other surveys..
I suspect that the related IR source may correspond to the 1 of the 2 galaxies near SDSS J140224.25+244224.3
Spot On @1001G 😃
a #bent #corejet perhaps?
Great find @andymarrison! #merger
Sí este es el caso 😃
This is a tough one. It could be a mix of compact & extended sources or radio lobes from a single source.
This is the core of NGC3628, a starbursting edge-on spiral galaxy 😃

looks somewhat #bent to me... deeper follow-up observations would help with this source
I think that an offset of 161.19 arcmin is too large to be related to this system given the redshift of this object.
Yes, this a merger system and the galaxy on the left is a radio galaxy.
Thanks Zutopian. Yes, unfortunately we do not know if the blobs are correlated so to be safe each blob is posted as a different subject
looks like a #bent #wat to me. see heinz's post: http://blog.galaxyzoo.org/2014/01/16/more-information-on-tailed-radio-galaxies-part-1/
I think this is a #multiple and all 3 blobs of emission are coming from the IR source which is coincident with the middle radio source
no worries thanks for the heads-up 😃
No worries. Thanks for the note 😃
I think it looks more like #corejet. Check out http://radiotalk.galaxyzoo.org/#/boards/BRG0000001/discussions/DRG000000d for more info
I'd say this is a #compact as we can still see the IR source 😃
It's a bit too far to tell. In general a spectrum gives you the general age of the stellar populations. Can't really tell you if it's a disk
some hints of optical AGN activity in the lines but [oiii] and Hb lines are too weak to tell
@kevinschawinski and I had a look at the spiral's spectrum below and we agree that it's fairly normal one for an old dusty spiral.
(more info: http://mendozza.org/sergio/phdthesis/phdlatex2html/node13.html)
Excellent example of a double jet or #hourglass. Not sure it is a WAT but the topside might be #bent
I agree with that.
Nice #wat. There is also a possibility of 2 separate sources and a #bhgroup? ..
The proximity to the #star is not helping.. but perhaps so..
I think so too.
I am not sure that the tail is real. Agree that it's a background IR galaxy though 😃
The energetics are also extreme. I'm just glad that there aren't too many of these near the Milky Way... 😉
Good work. Too bad that we are foiled by #stars again 😦
FWIW my suspicion is that this is a #bhgroup (4 individual #compact), of which 2 other members lie #overedge
the "snowflake" distribution suggests #artefacts. See this: http://radiotalk.galaxyzoo.org/#/boards/BRG0000005/discussions/DRG0000006 😃
Fantastic! This looks like a Narrow Angle Tail to me. Check out: http://www.youtube.com/watch?v=_wrn7WxHA5A for a simulation
Yes, I agree 😃
looks likely 😃
Would be interesting to get higher angular resolution observations to see what is going on with the southern plume. #hourglass - like
#overedge? maybe it's like 3C175: http://images.nrao.edu/images/3c175ci.gif
Wow! That sounds incredibly far for such a big source. @HAndernach or @DocR: is this a giant?
Great! Also #hourglass? Looks like a smaller version Centaurus A (http://galaxyzooblog.files.wordpress.com/2013/12/cena_radio_atca_sm.jpg)
Apologies. We are missing this field because there is a bright IR source (#star?) at the edge
Excellent! Definitely worthy of further investigation 😃
see some artefact from a #star as well 😃
Apologies again for the blank IR field 😦 Thanks for the heads-up!
Brilliant! What a great find!
Further investigation is certainly needed for a few of these "blank IR" fields. We're looking into it so we hope to get some answers soon.
good spotting 😃
or could this be a #double lobe ? 😃
I think it's a #bent #double #overedge 😃
Very nice! 😃
yes, http://third.ucllnl.org/cgi-bin/firstimage?RA=11.019 %2B36.560&Dec=&Equinox=J2000&ImageSize=10&MaxInt=10&GIF=1

Could = wat because looks in a cluster:
It could be. I'm not sure about this one. Am unsure how much of the filament is artefact vs real.. 😦
Wow! This is an #Xshaped source! This could be a double black hole system with 2 separate jets! Most awesome find 😃
unlikely to be a merger 😦 but nice pair! 😃 check out this sdss image: http://cas.sdss.org/dr6/en/tools/chart/chart.asp?ra=197.2&dec=14.66
too bad about the #star (s)... 😦
It could be 😃
There are some artefacts from the processing but the peaks are strong enough that they look real 😃
Looks like a one-sided jet. Possibly a #headtail because it looks tadpole 😃
Yes, I reckon so! This is certainly #bent and looks like a wat. This is awesome! 😃
Could actually be a more distant version of this: http://radiotalk.galaxyzoo.org/#/subjects/ARG0001kqx ... (ie. a distant cluster?) ..
This is spectacular! 😃 I suspect they all belong to 1 galaxy and is a pair of #bent jet + a #corejet 😃
possible... or it could belong to one of the IR sources near it. Further redshift information is required to verify this...
@jipee, yes, the jets are being blocked by a pair of galaxies in the foreground 😃 Nicely spotted!
Yeah, I reckon it's an #overedge and unless we can see a larger field of view, it's hard to tell what it is.... 😃
Yep, looks like a distant cluster of #IFRS 😃
Looks like a one-sided #plume from an #IFRS... Thanks for noting this 😃
Could be... @mini_mintaka: as the local expert, what do you think?
I am not sure I believe that little contour in the middle (well the middle blob of the one you IDed as a 3lober) but I could be wrong....
This is a tough one but I think that we could be seeing a #corejet in the central source and then the source to its 10o'clock is a #plume
No worries. Thanks for the heads-up 😃
The central galaxy has saturated the colour scaling so the background appears quite dark 😃
The structure also depends on the orientation of the jet with respect to our line-of-sight so it's not an easy question to answer 😉
This galaxy appears to be either in a group or a cluster. The jet/lobe structure can be distorted by the group/cluster environment.
It is difficult with the stripe/#artefact but I believe that you are right. This is a #triple 😃
I'd hazard a guess that it's the one between the lobes but it's one of those uncertain ones 😦
yep #star 😦
I reckon it's one source 😃 And yes, it is blocked by the star in the IR image 😦
I think it's the poor IR resolution. SDSS equivalent : http://cas.sdss.org/dr6/en/tools/chart/chart.asp?ra=191.53916977&dec=38.80827291
Sorry this is one with a missing IR map. 😦
Another tough one. Same frame in SDSS looks like this: http://cas.sdss.org/dr6/en/tools/chart/chart.asp?ra=191.53916977&dec=38.80827291 😃
or the noinfrared source could belong to one of the galaxies near it. this is a tough one 😃
or it could be a core + a double lobe since all 3 lie in a line ...+ 1 noinfrared i the north
Very unusual indeed. It's either a #corejet or a mishapen #hourglass.. Definitely deserves further investigation 😃
Some artefacts in the image but I reckon that if you slid the slider all the way to the radio end, it looks like double jet 😃
yeah it's missing the IR image... sorry 😦
Might be. I just sent your report of the bug to the programmers...
latest findings suggest a cluster.... Great Stuff!
Yes, it does look like that..... Unless it's actually a #doublelobe with a very short jet on one side. The low resolution makes it harder
The middle one looks like a #plume to me (probably not enough resolution/sensitivity to tell #headtail). Bottom one is #doublelobe
The brightest intensity in this frame may have saturated badly and fooled the auto-colour scaling algorithm into darkening the background
there seems to be 2 radio sources. One is the #compact source in the middle and another at bottom-right is a #corejet + #noinfrared
Our field-of-view has been blocked by an intervening nearby galaxy
This looks like you are being obscured by some massive nearby galaxy because this patch looks like a part of a spiral...
Yes, you have a #compact behind a Galactic #star 😃
wow this is amazing! #bent
Bummer! This #hourglass source is behind a Galactic star. 😦
very cool 😃
This is probably a nearby system because if it's further away, it could look more like a #doublelobe
This looks like a #hybrid but it's also #overedge
The bottom one is a bit of a mystery because we can't really see where else it could go so it's #overedge
LOL no. This IR field was observed by WISE, an IR satellite telescope. The stripe could be an #artefact or diffraction spike from a #star
Looks like a pair of galaxies and one of them have a #corejet 😃
this is a galaxy with a #doublelobe and another with a one-sided #plume
Thanks heaps for your patience and help. I hope it works more smoothly for you in future.
This is a tough one. It could be a #compact or it could be a #plume from the galaxy below the main radio peak.
nearly an #hourglass too 😃
Yes, it's a small #doublelobe jet. 😃
Interferometry correlates the signals from many spaced out smaller telescopes to mimic the observing power of a very big telescope
Aah yes, you are seeing the lattice-like structure that is characteristic of interferometric imaging.
This is epic! Wow indeed! What a beauty!
This is a tough one. It could also be #doublelobe ....Definitely further investigation is needed since it's a crowded field
Very well spotted!
Very nice. Yes, I'd say so 😃
LOL! isn't it always the case that Mother Nature does tease us a little 😉
Ja, det ligner et artefakt (#artefact) 😃
A #doublelobe, I reckon 😃
Yes, I concur with @planetaryscience. The #star is definitely obscuring the view of the IR galaxy 😃
Yes, it's a core + a double lobe 😃
Nice! I'd call this a #corejet 😃
Yes, I concur. This is definitely a very nice example of a #corejet
I'd say that it's an #hourglass 😃
Yes, you are seeing two-sided jet off the IR galaxy in the middle.
spoton! 😃 #noinfrared
I think you're right #noinfrared 😃
Lovely jet! Yes, possibly #corejet or even #plume or even #overedge 😃
I vote for #messy and #artefact 😃 But definitely worth following up. 😃
This is a nice #hourglass but I think the source to its left is a #star
I think that these are probably 2 separate sources. Centre one is a #compact. The source on right might belong to the galaxy on its right.
Note the large stripey structure is an #artefact from processing such an overbright and large source
Wowwee! I think that you're seeing a part of a very large structure here so I suspect this is #overedge.
This is a very nice #corejet 😃
Awesome! A #doublelobe 😃
We are calling these #hourglass 😃
@mini_mintaka. You could be right. Am not sure of myself now...
I suspect there is a very bright source/star near the field that is saturating the detector. #star
Probably #bent and asymmetric radio source. But it can also be a background source. Might need redshift to confirm.
#plume. This is interesting
It's actually quite difficult in bent sources but if we assume a simple linear jet, it's usually the source that lies in a line with the jet
Yes, I'd agree with that. 😃
some jets are more blobby that others and the connection between the blobs is sometimes seen if our observations are sensitive enough
#artefact That weird line is a processing artefact. We are trying to probe as close to the noise as possible so we will see these artefacts
You are likely to be seeing 3 bright spots in a one-sided jet #jet
