the many smaller radio sources are image #artefacts.
This is the telescope response to a really bright source in the radio. The bright source in the middle is the radio source.
Yes, that does look like a merger in SDSS

The two bright infrared blobs are two stars from our own galaxy. If you click on the SDSS link above you will see the stars.
Looks like one
Ah yes, thanks! I got the RG but was struggling with the TD
or Triple?
I still can't access FIRST to see the larger image. Either way, this is interesting
Agree!
Sorry what is a TDRG?
does the link above work or do you search FIRST elsewhere?
Love seeing "unusual" and "weird"!
Surprised that there is no IR if it has a host of STAR in SDSS.
Need to check FIRST --> system still down.
Looks bigger in NVSS. Can't load FIRST to check.
The resolution of WISE is pretty low. As a result, the host galaxy could be merged into the bright galaxy. This could explain the #offset.
I agree. I think this one is interesting. I don't recall ever seeing something like this before.
Redshifts are similar at 0.21, indicates that we have a group.
Are there redshifts for the host galaxies?
looking at SDSS, this may be the result of low SNR in the other colours making the colour image.
That does indeed look like a #wat in NVSS
#green #outflow although not associated with the radio source
#outflow
Indeed! Looks like a lot of diffuse emission in the lobes.
I wonder if the radio here covers all the "string of pearls" galaxies.
It does look like that in the SDSS image. Very organised set of galaxies!
could very well be. Does look promising.
Indeed! Click on the SDSS link above and you will see a nice edge on spiral galaxy. The radio comes from star formation and not a BH.
centre radio close to #green galaxy but could be separate and an #ifrs
What do you consider to be "strange" about this one?
This could be classified as a #double. The radio emission here is tracking a supermassive black hole.
what is W/SW?
I agree! Nice catch
This is a neat #triple. Interesting in the infrared too.
In radio this would be a #double as there are two radio "blobs". This is an impressive radio source!
great description nilium! Click on the the FIRST link below the image and you will see that this is #overedge. The radio source is big!
yes I would say that these are two unrelated radio sources
indeed, nice find!
@inlovewspace: you may see what looks like radio emission but it is not highlighted because of the signal to noise of the image
Hi PolishPlanetPursuer, this would be a #triple. Two lobes and a core. The core overlaps with the host galaxy.
or the radio jet could be moving around, like you would with a garden hose.
Beautiful, isn't it? This is an #x-shaped radio galaxy. The structure could be the result of the environment (group, cluster, etc.)
a wide-angle tail (WAT) or #bent
Indeed. We can also classify this as #double-lobed
yes the radio data seem to have an error in it.
yes, a #triple and #overedge
Yes, that does look like two radio sources
#overedge
yes this would be a #doublelobe
Good catch!
I would have said that this was one radio source. Not sure what you mean by #artefact
#triple or more
We would call this infrared faint. #ifrs
on the left is the telescope's response to a star. The larger WISE image should show the star.
looks #green to me too. a green SDRAGN?
This is the response of the telescope to the bright radio source.
yes, this is an #artefact and the only real radio source is the one at the centre. Happens with a bright radio source.
very interesting indeed
#cluster ?
This one is complicated!
or two galaxies based on the SDSS image?
looks like the southern lobe is very faint. Nice find!
JeanTate is correct. I wonder if this is #restarted (more than 1 episode of black hole activity).
Very interesting #green one. Merging galaxies?
oooh, very nice. looks like two black holes merging
bright core faint lobes
#bent #triple. Nothing in optical and very faint IR
Nice #triple
maybe #core-jet based on SDSS image
#hybrid
very interesting. NVSS looks like the host is the bright IR just below the top radio source. Resolution seems to playing a role here.
looks like it to me - Great find!
This one is nice. I wonder if the two radio sources are related...
The radio emission is the result of star formation in this galaxy and not from an active black hole.
looks like an #xshape
If it is a #relic, should show up in lower frequency observations. Maybe VLSS
Very faint radio lobes.
This is really nice and may be considered #bent
Can you explain what you mean by #artefact in this case? This looks like two radio lobes.
Can you explain what you mean by "no radio images"?
my thought is that the centre radio is one source. The larger FIRST image suggests that the upper left radio source is a lobe to another.
Radio jets can be determined but not IR jets. This looks to me like the radio jets stay collimated until they pass through the host galaxy
This is how the contours look for a bright radio source.
That is most likely another radio galaxy.
The bright infrared object is a star and the radio emission looks to be coming from the galaxy to the south.
This looks to be #overedge and maybe #giant. Looking at the FIRST link above.
This is why we require higher resolution radio data to cross-match with these new IR and optical surveys.
a number of IR sources. Since the radio seems to be focused on the central bright IR galaxy, that would be the galaxy hosting this radio
This is an ATLAS image and has lower resolution than the "normal" RGZ images that you have probably seen. As a result, the radio covers
Part of RGZ is to determine which components belong to which galaxy. We don't know this ahead of time.
Each of the separate radio components will be centred in the image so this source will come up 3 times but from different viewing positions.
or #bent
The radio emssion looks to be a #NAT
The resolution of the infrared is better in SWIRE than in WISE which is why they "appear smaller".
The SDSS does not go as deep as the radio data so a number of our radio sources may not have an optical host in SDSS.
The majority of sources like the one above, the radio emission is from an active black hole.
Depending on what the host galaxy looks like and where the radio emission is from can tell you if the black hole is active.
Great question! If you click on the SDSS link above you will get more information on the host galaxy.
Agreed! Looks to be a cluster or group
This one is great!
I don't think this would be a WAT but I agree that it could be a triple
an ATLAS source. Not sure what you mean by #wat.
interesting shape to the spiral galaxy beside this one
Yes, this galaxy will have a black hole in the centre. It is active and we observe this radio structure.
Agree. The northern lob is really faint in FIRST but stands out in NVSS
I would say no. Just looking at the FIRST image on the link above.
Many candidate host galaxies, nothing I could pin down.
Yes a nice #overedge and #double.
SDSS image points to a possible #cluster
Clicking on the FIRST link above shows this to be an #overedge radio source and a rather interesting one.
The radio emission is most likely originating from the star forming regions in the galaxy and not the central black hole.
The host should not be a star. Is that just a SDSS classification error?
I do like your sense of humour 😃
This is a #triple or #doublelobe. More specifically a FRII radio source.
and potentially #bent
Not too sure. On my list to follow-up
We thought we had this fixed, thanks for bringing this up. Maybe we can track this down now.
I think that this may be an #artefact but the central radio source is indeed a source.
Looks like we may be beginning to see the jets.
hard to tell if this is #green, I'll add it to the list to investigate further.
Could be the result of beaming too.
A merging system. Needs to be followed up if the radio structure further away is connected.
Interesting! Restarted radio sources are rather fascinating.
If you click on the SDSS link below the image you will see the optical image. In this case the source is a nice spiral galaxy.
I'm going to call this #green, even though it isn't technically green. More for a note to myself.
I would say yes.
This one is rather interesting. Looks like a curved jet connecting the core to the lobes.
Clicking on the SDSS link below the image would show what the IR source is. however, in this case, there is no SDSS data 😦
This IR signature would indicate a star forming galaxy seen face-on, most likely a spiral galaxy with an active black hole.
Looking at the larger FIRST image, did you measure the size based on the far north faint lobe?
I don't see a #green tint. This may be a group though. Just need some redshifts.
I would say #hourgalss but it may be a one-sided jet as the host is not in the centre.
Does look #green but it is not detected in WISE band 4......
Thanks! In my work on ifrs I have only come across a couple of resolved ones, the majority are compact.
However, the central radio does line up with an IR galaxy.
This one is difficult. I would say that the compact IR (SW) is the host and that we only see one lobe (in the centre).
Funny how the majority of #IFRS are compact. Anyone seen a #IFRS #doublelobe or #hourglass?
Agreed! If you click on the SDSS link, you will see that the host galaxy is a nice elliptical. Very typical of active black holes.
We cut the contours at a signal-to-noise = 5 so the "spot" you suggest could be real but it just fell below our cutoff.
The radio source is located in a nice spiral galaxy. If you click on the SDSS link below the image you will see the optical image.
If you click on the FIRST link at the bottom of the image you will see the other side of the radio source. This is called #overedge.
Yes this would be a QSO. The SDSS is known to have labelled some QSOs as Stars.
Interesting too that the SDSS image is pretty empty too.
Nice source, looks to be in a cluster or group.
Not too sure what you mean by "halo".
This is where the optical image may come in handy. Looks like there may be a counterpart for the two radio (centre and left).
Indeed, even the SDSS image looks interesting.
This is a nice looking radio galaxy. I say the hourglassPlume tag works just fine here.
This is a great example to use. I'll forward this onto others. Thanks!
Nice. Looks like there are two IR galaxies close together (same in optical). May be responsible for the WAT like structure.
I don't see the over-edge part. Can you point that out to me?
Will need to investigate. I like this one!
This is weird. Question: is this a double lobe with the faint IR host with no radio and a hotspot at the very south of the image? No idea
Indeed. When I clicked on the SDSS link, there was no optical counterpart. So we have radio and infrared. Interesting!
However, I wouldn't rule out the starburst. Whether the two spirals are interacting needs more info on the redshifts of the two.
This is an interesting source. I would say that the spiral galaxy with the radio counterpart is a Seyfert galaxy, so an active black hole.
The IR is coming from a nearby star. If you look at the SDSS image you can see the star in better detail.
Indeed! 😄
Yes, this is indeed a nice #WAT. Interesting that the core of the radio may not line up with any IR source.
That is a nice elliptical galaxy with a #doublelobe radio source.
#triple, slightly #bent.
Hard to say if this is #overedge. I probably would have marked it as isolated with no IR, a #corejet.
I would agree. Looks like the host IR galaxy is on the right edge of the image.
This one is interesting. I wonder if it is the remainder of a once active black hole from the nearby galaxy in the SDSS image...
@Jacko99 - Welcome to Radio Galaxy Zoo! Do let us know if you have any other questions.
I agree. Maybe a little #bent too 😄
Looking at the larger WISE image (link below the image), there is a bright #star nearby that is saturating the image.
The strange line is coming from a a bright nearby #star. If you click on the WISE link below the image you can see a larger IR image.
@Jacko99 - yes I would say this is extended. If you click on the FIRST link below the image you can see a much larger radio image.
Lovely #wat and #compact radio objects.
Agreed that this one is #overedge. I would say that the IR source is the one right between the two radio contours with no radio on top.
This is indeed #messy and a #bhgroup. A great find!
The radio source in the upper left is #overedge and the radio source in the centre is separate.
Yes this is a #triple as there are 3 distinct radio "blobs" and one infrared source.
Although SDSS says this is a star, I would agree that this is a quasar.
Yes, there are a few artifacts in this radio image as the radio source is bright.
A lovely elliptical host galaxy.
This is a nice #bent one. Not too sure what is going on here. Almost a perfect 90 deg turn!
Yes, but FIRST goes deeper than NVSS. Maybe, maybe not 😄
Agreed! You have a good eye!
This one is beautiful! A definite #triple and maybe a #hybrid. If you look at the larger FIRST image the lower lobe has a hotspot
This is a very faint radio source in the FIRST survey. But the #artefacts do make me wonder if this is real.
This is most likely a precessing jet.
Yes #extended. Could be a #hybrid.
I think that those diagonal strips are #arefacts
This is a nice elliptical galaxy (see SDSS). The radio emission is contained within the elliptical galaxy.
This is very interesting! Could also be #bent or a #WAT, really hard to say. Need to follow-up on this one.
Yes, I agree. A #overedge #doublelobe. The IR galaxy above the brightest IR galaxy I would say is the IR counterpart.
If the radio pile up is only seen in one of the two lobes, I would say it is a #hybrid. Not the case here.
I don't think that this is a #hybrid as the majority of the radio emission is piled up that the edges furthest away from the IR galaxy.
This is another #bent radio source. The upper lobe has a nice 90 deg curve to it.
Both radio lobes seem to be pointing to each other suggesting that one of the IR sources in between the two lobes is the host galaxy.
This is a great #bent radio source. The left had lobe is perpendicular to the right hand lobe.
Ah yes, one of these sources that lies outside the SDSS coverage.
Yep! A nice #doublelobe indeed.
The IR counterpart would be the galaxy just outside of the radio contours of the upper radio lobe.
Yep, a #doublelobe and #overedge. The larger FIRST image shows a really typical looking #doublelobe radio source.
would be located at the very centre of the radio contours. The brighter IR source near the centre I would say is not related to the radio.
This is a nice #doublelobe and #hourglass radio source. Looks like the infrared counterpart is much fainter and
Yes, this is a #overedge. Looking at the larger FIRST image, the lobe on the other side is much fainter and off to the upper right.
This looks like a single radio source with #noinfrared counterpart.
Yes, this would be a #triple as the central radio contour overlaps nicely on the IR galaxy and the two other radio contours have no IR.
Nice #doublelobe with with two beautiful #jets coming from the central faint infrared galaxy.
#overedge - a nice radio AGN with a potential #hybrid lobe structure.
Indeed!
I would say that is a bright infrared galaxy with a nice radio core.
I think the other lobe is out of the image at the bottom left. It still amazes me that these powerful jets/lobes can bend like that!
The one on the left looks like a #WAT, maybe? Too bad the source is #overedge 😦
By perpendicular, I mean, going in and out of the page.
Beautiful! I'll be looking at this one sometime soon. The radio emission should be perpendicular to the lovely spiral arms.
I love these ones!
This one is interesting! I want to have a closer look at the IR.
have one lobe fainter and/or more diffuse than the other lobe.
Radio sources can expand to rather large distances from the host galaxy. A majority of the larger sources will ....
This looks like a large #doublelobe. The one lobe overlaps nicely with the IR source and the second lobe is fainter and further away.
Yes, the infrared source in the middle of the #doublelobe is associated with the radio source.
Need to follow-up on this one!
Sure is! Almost #overedge.
What is going on here!?! A #WAT?
This is nice! Almost a #xshape!
I wonder if that other IR galaxy at the top of the lobe is playing a role in how the lobe is shaped...
A nice #triple
This one is great! #bent, #WAT, galaxy group.
#star
This is a great #WAT!
@biggsjrex, just one mark in the centre of the infrared source will do. Excellent question!
Yep, #noinfrared.
#noinfrared source here. The radio is really nice!
That #doublelobe is a beauty!
Rather tough isn't it? I have a hard time with a lot of sources. This is another reason why we are doing this project. 😃
I would say the faint IR source is the match. (Sorry not enough characters in the comment window)
Another tough one! Since there is a very faint infrared source in between the two radio lobes beside the bright IR source....
If there is no infrared source, there should be a button that says "no infrared". Thanks for all your classifications 😄
I would say that the radio is not from the bright IR source. Although you could very well be right. I would need to look into this one.
This could very well be coming from the bright infrared source. Since there is no radio emission on the other side of the bright IR source
Another nice #doublelobe. 😄
Too bad there is a #star in the way 😦
This would be a #doublelobe.
Very interesting! A nice #bent radio source.
Oh dear. Hope there is only a few of these.
This one is great! I have no idea what the radio source is, looks very odd.
Indeed! We had to automatically adjust the infrared image and looks like our code didn't quite work properly here 😦
Very odd. Will have to look at how the IR image was generated. Thanks for pointing this out!
Yes it is. Beautiful isn't it?
Looks to me like the central radio source is a lobe of the vertical jet in the centre of the bright infrared source. Nice!
Wow! This one is very interesting. We will have to do a follow-up. 😄
This is very similar to the spikes from stars in optical and infrared images. The radio source is real, the hexagon is an #aretfact.
Yes there is a hexagon pattern. The radio galaxy is very bright and the radio telescope has a hard time dealing with this.
Bad infrared data 😦 #artefact
The infrared galaxy is probably a edge-on spiral galaxy.
I see. Those have to do with the computer display and the way the contours are rendered on the screen. Nothing to do with the radio source
Can you explain what the "line-thingies" you mean?
Another great example of a #doublelobe.
The source in the centre is #bent. A great example of how radio lobes can be moved around either by the black hole or from the environment.
This is why I am an astronomer, I love finding crazy things like this! I'm off to figure this one out.
What is this???? 😄 😄 😄
The radio looks like it has done a 90 degree turn. 😄
There is a lot of #artefact in this one. The central radio source is bright enough for us to say this is real!
Very interesting either way!
Hard to say with this one. Could be a large faint radio #doublelobe or an #IFRS with noise at the top left. More investigation is needed.
The central galaxy may be too faint for the infrared telescope to detect.
Another great example of a #bent radio source!
Good eye!
Indeed! Adding this to the list of source I need to follow up on.
Maybe #bent too. If a radio source is #bent, can tell us about the environment of the galaxy.
This is a great image! We will need to follow-up on this one, the #diffuse structure is very interesting.
I would mark that as a #doublelobe with a really faint IR galaxy. Hard to see though.
Wow crazy! Some of these could be #artefacts and some could be true sources. A definite follow-up!
Since the radio jets (narrow part) are touching too and the round radio emission is separated by the jet, this would be a #doublelobe.
Yes, the two IR sources are touching and we will have to determine which one the radio jets are coming from.
That may be a really bright galaxy too (ellipitical or face-on spiral?) and not a #star.
You can toggle between lines and no lines. Hope this helps. Thanks for pointing this out.
Yes they do and can be frustrating at times! In the interface we have put a button on top right that allows you to remove the contours.
Could be an #artefact but also some really #diffuse large scale structure. A definite follow-up!
No worries! Thanks for letting us know and for your classifications.
The radio is very interesting. These look like two #diffuse #doublelobes. Too bad there is a #star in the infrared 😦
A large number of infrared sources around too. I wonder if this is a group or #cluster?
A beauty! another one for follow up. The infrared looks very interesting too.
Great find! We will have to follow up on this one, maybe try to see if we can detect the jets connecting the radio to the infrared.
I'm hesitant about this one. Some of the radio image looks like an #artifact. Need to investigate further.
The fact that there are very few bright IR sources is interesting in itself. Most of the images so far show lots of IR sources.
Yes - repeated and rather symmetric 'wings'.
More info on #artifacts available here: http://radiotalk.galaxyzoo.org/#/boards/BRG0000005/discussions/DRG0000006
Yep, #artifact. The radio source would be the circular part and the 'x' shape is a result of the image creation.
Another interesting source to investigate further. Thanks for all your work and tagging sources!
This could be another IFRS (http://arxiv.org/abs/1312.1002). These are very distant radio sources.
Nice #bent source
The central radio source has two IR counterparts. The source in the lower let is most likely a separate radio source with its own IR.
Quite possibly a cluster. I've noted this one for follow-up.
We don't have the distances to most of these radio sources so I can't tell you how big these sources are. Each image is 3 arcmin x 3 arcmin
The resolution of the IR image is rather low. We would require a followup to see if the IR source is indeed two IR galaxies, radio on one.
Could also be an edge-on radio source. Instead of looking the big radio lobes, the radio galaxy is turned.
This is another excellent source. Too bad about the #star again. Will have to dig around for other images.
Will do! I'm making a list right now with names of those who have found the different objects.
This is wonderful! I'm really excited that people are marking their favorite ones. Looking forward to the science outcome.
This is a nice #bent source. The #star from our galaxy will cause some issues when we look further into this source 😦
Marking for follow-up.
Although the lower radio source could be connected to a different IR source. This may be a #bhgroup or cluster of IR galaxies.
This one is amazing! I would say that both radio contours are connected with the central IR source.
These ones just amaze me! Excellent find!
I'm marking this one for future following. The infrared galaxies are intriguing!
This one is nice! The bending could be a result of the radio emission with its environment.
More followup is need to verify that this is indeed an IFRS. IFRSs are currently only observed in the radio!
These types of galaxies are interesting and have the potential to be one of the few infrared faint radio sources (IFRS).
Could be. I'm in the process of tracking down the data.
Another interesting #hourglass. Confused about the IR sources all being lined up.
This is an example of a star from our Galaxy seen in IR and the radio galaxy is behind the star and we can get no information from it. #star
One to follow-up on! #messy
Interesting indeed! #messy
Not too sure what this one is #halo? #relic? Interesting! Will have to follow up/
This is a difficult one! I would say that the radio is two lobes separated from the central infrared source.
That is a great example of an #hourglass. Beautiful!

This is the telescope response to a really bright source in the radio. The bright source in the middle is the radio source.

This is a #triple or #doublelobe. More specifically a FRII radio source.
and potentially #bent
Not too sure. On my list to follow-up
We thought we had this fixed, thanks for bringing this up. Maybe we can track this down now.
I think that this may be an #artefact but the central radio source is indeed a source.
Looks like we may be beginning to see the jets.
hard to tell if this is #green, I'll add it to the list to investigate further.
Could be the result of beaming too.
A merging system. Needs to be followed up if the radio structure further away is connected.
Interesting! Restarted radio sources are rather fascinating.
If you click on the SDSS link below the image you will see the optical image. In this case the source is a nice spiral galaxy.
I'm going to call this #green, even though it isn't technically green. More for a note to myself.
I would say yes.
This one is rather interesting. Looks like a curved jet connecting the core to the lobes.
Clicking on the SDSS link below the image would show what the IR source is. however, in this case, there is no SDSS data 😦
This IR signature would indicate a star forming galaxy seen face-on, most likely a spiral galaxy with an active black hole.
I would say yes.
Looking at the larger FIRST image, did you measure the size based on the far north faint lobe?
I don't see a #green tint. This may be a group though. Just need some redshifts.
I would say #hourgalss but it may be a one-sided jet as the host is not in the centre.
Does look #green but it is not detected in WISE band 4......
#green

#green
Thanks! In my work on ifrs I have only come across a couple of resolved ones, the majority are compact.
However, the central radio does line up with an IR galaxy.
This one is difficult. I would say that the compact IR (SW) is the host and that we only see one lobe (in the centre).
Funny how the majority of #IFRS are compact. Anyone seen a #IFRS #doublelobe or #hourglass?
Agreed! If you click on the SDSS link, you will see that the host galaxy is a nice elliptical. Very typical of active black holes.
We cut the contours at a signal-to-noise = 5 so the "spot" you suggest could be real but it just fell below our cutoff.
The radio source is located in a nice spiral galaxy. If you click on the SDSS link below the image you will see the optical image.
If you click on the FIRST link at the bottom of the image you will see the other side of the radio source. This is called #overedge.
Yes this would be a QSO. The SDSS is known to have labelled some QSOs as Stars.
Interesting too that the SDSS image is pretty empty too.
Nice source, looks to be in a cluster or group.
Not too sure what you mean by "halo".
This is where the optical image may come in handy. Looks like there may be a counterpart for the two radio (centre and left).
Indeed, even the SDSS image looks interesting.
This is a nice looking radio galaxy. I say the hourglassPlume tag works just fine here.
This is a great example to use. I'll forward this onto others. Thanks!
Nice. Looks like there are two IR galaxies close together (same in optical). May be responsible for the WAT like structure.
I don't see the over-edge part. Can you point that out to me?
Will need to investigate. I like this one!
This is weird. Question: is this a double lobe with the faint IR host with no radio and a hotspot at the very south of the image? No idea
Indeed. When I clicked on the SDSS link, there was no optical counterpart. So we have radio and infrared. Interesting!
However, I wouldn't rule out the starburst. Whether the two spirals are interacting needs more info on the redshifts of the two.
This is an interesting source. I would say that the spiral galaxy with the radio counterpart is a Seyfert galaxy, so an active black hole.
The IR is coming from a nearby star. If you look at the SDSS image you can see the star in better detail.
Indeed! 😄
Yes, this is indeed a nice #WAT. Interesting that the core of the radio may not line up with any IR source.
That is a nice elliptical galaxy with a #doublelobe radio source.
#triple, slightly #bent.
Hard to say if this is #overedge. I probably would have marked it as isolated with no IR, a #corejet.
I would agree. Looks like the host IR galaxy is on the right edge of the image.
This one is interesting. I wonder if it is the remainder of a once active black hole from the nearby galaxy in the SDSS image...
@Jacko99 - Welcome to Radio Galaxy Zoo! Do let us know if you have any other questions.
I agree. Maybe a little #bent too 😄
Looking at the larger WISE image (link below the image), there is a bright #star nearby that is saturating the image.
The strange line is coming from a a bright nearby #star. If you click on the WISE link below the image you can see a larger IR image.
@Jacko99 - yes I would say this is extended. If you click on the FIRST link below the image you can see a much larger radio image.
Lovely #wat and #compact radio objects.
Agreed that this one is #overedge. I would say that the IR source is the one right between the two radio contours with no radio on top.
This is indeed #messy and a #bhgroup. A great find!
The radio source in the upper left is #overedge and the radio source in the centre is separate.
Yes this is a #triple as there are 3 distinct radio "blobs" and one infrared source.
Although SDSS says this is a star, I would agree that this is a quasar.
Yes, there are a few artifacts in this radio image as the radio source is bright.
A lovely elliptical host galaxy.
This is a nice #bent one. Not too sure what is going on here. Almost a perfect 90 deg turn!
Yes, but FIRST goes deeper than NVSS. Maybe, maybe not 😄
Agreed! You have a good eye!
This one is beautiful! A definite #triple and maybe a #hybrid. If you look at the larger FIRST image the lower lobe has a hotspot
This is a very faint radio source in the FIRST survey. But the #artefacts do make me wonder if this is real.
This is most likely a precessing jet.
Yes #extended. Could be a #hybrid.
I think that those diagonal strips are #arefacts
This is a nice elliptical galaxy (see SDSS). The radio emission is contained within the elliptical galaxy.
This is very interesting! Could also be #bent or a #WAT, really hard to say. Need to follow-up on this one.
Yes, I agree. A #overedge #doublelobe. The IR galaxy above the brightest IR galaxy I would say is the IR counterpart.
If the radio pile up is only seen in one of the two lobes, I would say it is a #hybrid. Not the case here.
I don't think that this is a #hybrid as the majority of the radio emission is piled up that the edges furthest away from the IR galaxy.
This is another #bent radio source. The upper lobe has a nice 90 deg curve to it.
Both radio lobes seem to be pointing to each other suggesting that one of the IR sources in between the two lobes is the host galaxy.
This is a great #bent radio source. The left had lobe is perpendicular to the right hand lobe.
Ah yes, one of these sources that lies outside the SDSS coverage.
Yep! A nice #doublelobe indeed.
The IR counterpart would be the galaxy just outside of the radio contours of the upper radio lobe.
Yep, a #doublelobe and #overedge. The larger FIRST image shows a really typical looking #doublelobe radio source.
would be located at the very centre of the radio contours. The brighter IR source near the centre I would say is not related to the radio.
This is a nice #doublelobe and #hourglass radio source. Looks like the infrared counterpart is much fainter and
Yes, this is a #overedge. Looking at the larger FIRST image, the lobe on the other side is much fainter and off to the upper right.
This looks like a single radio source with #noinfrared counterpart.
Yes, this would be a #triple as the central radio contour overlaps nicely on the IR galaxy and the two other radio contours have no IR.
Nice #doublelobe with with two beautiful #jets coming from the central faint infrared galaxy.
#overedge - a nice radio AGN with a potential #hybrid lobe structure.
Indeed!
I would say that is a bright infrared galaxy with a nice radio core.
I think the other lobe is out of the image at the bottom left. It still amazes me that these powerful jets/lobes can bend like that!
The one on the left looks like a #WAT, maybe? Too bad the source is #overedge 😦
By perpendicular, I mean, going in and out of the page.
Beautiful! I'll be looking at this one sometime soon. The radio emission should be perpendicular to the lovely spiral arms.
I love these ones!
This one is interesting! I want to have a closer look at the IR.
have one lobe fainter and/or more diffuse than the other lobe.
Radio sources can expand to rather large distances from the host galaxy. A majority of the larger sources will ....
This looks like a large #doublelobe. The one lobe overlaps nicely with the IR source and the second lobe is fainter and further away.
Yes, the infrared source in the middle of the #doublelobe is associated with the radio source.
Need to follow-up on this one!
Sure is! Almost #overedge.
What is going on here!?! A #WAT?
This is nice! Almost a #xshape!
I wonder if that other IR galaxy at the top of the lobe is playing a role in how the lobe is shaped...
A nice #triple
This one is great! #bent, #WAT, galaxy group.
#star
This is a great #WAT!
@biggsjrex, just one mark in the centre of the infrared source will do. Excellent question!
Yep, #noinfrared.
#noinfrared source here. The radio is really nice!
That #doublelobe is a beauty!
Rather tough isn't it? I have a hard time with a lot of sources. This is another reason why we are doing this project. 😃
I would say the faint IR source is the match. (Sorry not enough characters in the comment window)
Another tough one! Since there is a very faint infrared source in between the two radio lobes beside the bright IR source....
If there is no infrared source, there should be a button that says "no infrared". Thanks for all your classifications 😄
I would say that the radio is not from the bright IR source. Although you could very well be right. I would need to look into this one.
This could very well be coming from the bright infrared source. Since there is no radio emission on the other side of the bright IR source
Another nice #doublelobe. 😄
Too bad there is a #star in the way 😦
This would be a #doublelobe.
Very interesting! A nice #bent radio source.
Oh dear. Hope there is only a few of these.
This one is great! I have no idea what the radio source is, looks very odd.
Indeed! We had to automatically adjust the infrared image and looks like our code didn't quite work properly here 😦
Very odd. Will have to look at how the IR image was generated. Thanks for pointing this out!
Yes it is. Beautiful isn't it?
Looks to me like the central radio source is a lobe of the vertical jet in the centre of the bright infrared source. Nice!
Wow! This one is very interesting. We will have to do a follow-up. 😄
This is very similar to the spikes from stars in optical and infrared images. The radio source is real, the hexagon is an #aretfact.
Yes there is a hexagon pattern. The radio galaxy is very bright and the radio telescope has a hard time dealing with this.
Bad infrared data 😦 #artefact
The infrared galaxy is probably a edge-on spiral galaxy.
I see. Those have to do with the computer display and the way the contours are rendered on the screen. Nothing to do with the radio source
Can you explain what the "line-thingies" you mean?
Another great example of a #doublelobe.
The source in the centre is #bent. A great example of how radio lobes can be moved around either by the black hole or from the environment.
This is why I am an astronomer, I love finding crazy things like this! I'm off to figure this one out.
What is this???? 😄 😄 😄
The radio looks like it has done a 90 degree turn. 😄
There is a lot of #artefact in this one. The central radio source is bright enough for us to say this is real!
Very interesting either way!
Hard to say with this one. Could be a large faint radio #doublelobe or an #IFRS with noise at the top left. More investigation is needed.
The central galaxy may be too faint for the infrared telescope to detect.
Another great example of a #bent radio source!
Good eye!
Indeed! Adding this to the list of source I need to follow up on.
Maybe #bent too. If a radio source is #bent, can tell us about the environment of the galaxy.
This is a great image! We will need to follow-up on this one, the #diffuse structure is very interesting.
I would mark that as a #doublelobe with a really faint IR galaxy. Hard to see though.
Wow crazy! Some of these could be #artefacts and some could be true sources. A definite follow-up!
Since the radio jets (narrow part) are touching too and the round radio emission is separated by the jet, this would be a #doublelobe.
Yes, the two IR sources are touching and we will have to determine which one the radio jets are coming from.
That may be a really bright galaxy too (ellipitical or face-on spiral?) and not a #star.
You can toggle between lines and no lines. Hope this helps. Thanks for pointing this out.
Yes they do and can be frustrating at times! In the interface we have put a button on top right that allows you to remove the contours.
Could be an #artefact but also some really #diffuse large scale structure. A definite follow-up!
No worries! Thanks for letting us know and for your classifications.
The radio is very interesting. These look like two #diffuse #doublelobes. Too bad there is a #star in the infrared 😦
A large number of infrared sources around too. I wonder if this is a group or #cluster?
A beauty! another one for follow up. The infrared looks very interesting too.
Great find! We will have to follow up on this one, maybe try to see if we can detect the jets connecting the radio to the infrared.
I'm hesitant about this one. Some of the radio image looks like an #artifact. Need to investigate further.
The fact that there are very few bright IR sources is interesting in itself. Most of the images so far show lots of IR sources.
Yes - repeated and rather symmetric 'wings'.
More info on #artifacts available here: http://radiotalk.galaxyzoo.org/#/boards/BRG0000005/discussions/DRG0000006
Yep, #artifact. The radio source would be the circular part and the 'x' shape is a result of the image creation.
Another interesting source to investigate further. Thanks for all your work and tagging sources!
This could be another IFRS (http://arxiv.org/abs/1312.1002). These are very distant radio sources.
Nice #bent source
The central radio source has two IR counterparts. The source in the lower let is most likely a separate radio source with its own IR.
Quite possibly a cluster. I've noted this one for follow-up.
We don't have the distances to most of these radio sources so I can't tell you how big these sources are. Each image is 3 arcmin x 3 arcmin
The resolution of the IR image is rather low. We would require a followup to see if the IR source is indeed two IR galaxies, radio on one.
Could also be an edge-on radio source. Instead of looking the big radio lobes, the radio galaxy is turned.
This is another excellent source. Too bad about the #star again. Will have to dig around for other images.
Will do! I'm making a list right now with names of those who have found the different objects.
This is wonderful! I'm really excited that people are marking their favorite ones. Looking forward to the science outcome.
This is a nice #bent source. The #star from our galaxy will cause some issues when we look further into this source 😦
Marking for follow-up.
Although the lower radio source could be connected to a different IR source. This may be a #bhgroup or cluster of IR galaxies.
This one is amazing! I would say that both radio contours are connected with the central IR source.
These ones just amaze me! Excellent find!
I'm marking this one for future following. The infrared galaxies are intriguing!
This one is nice! The bending could be a result of the radio emission with its environment.
More followup is need to verify that this is indeed an IFRS. IFRSs are currently only observed in the radio!
These types of galaxies are interesting and have the potential to be one of the few infrared faint radio sources (IFRS).
Could be. I'm in the process of tracking down the data.
Another interesting #hourglass. Confused about the IR sources all being lined up.
This is an example of a star from our Galaxy seen in IR and the radio galaxy is behind the star and we can get no information from it. #star
One to follow-up on! #messy
Interesting indeed! #messy
Not too sure what this one is #halo? #relic? Interesting! Will have to follow up/
This is a difficult one! I would say that the radio is two lobes separated from the central infrared source.
That is a great example of an #hourglass. Beautiful!
