Galaxy Zoo Talk
I don't think I buy the "counter-image" to the top left though - too small to be real, too far out to have been lensed, probs just noise?
The z=2.2 could well refer to the red blob - I'm not sure, I don't know the CANDELs image display well enough!
Hi all! Looks like a high redshift galaxy with a lower z object next to and in front of it, but not massive enough to be strongly lensing it
Thanks C_cld, that helped a lot! Looks like a pretty cool merger to me, with colors perhaps due to strong emission lines in g and i images?

Like this one - nice well defined arc, probably a #lens. Worth digging in the center for the counter-image. #gradeB
Agreed that the arc orientation is not ideal. But there's a lot of mass there, including the dark stuff. Optimistically I might say #gradeB
Quite like that red arc, worth a closer look. Probably a lens? #gradeB
Not convinced that's an arc across the centre - but maybe just to its left? Possibly. #gradeC
OK, this image is full of other galaxies in the zoo. I see http://talk.galaxyzoo.org/#/subjects/AGZ0000988 there at 4 o clock
Not sure I like the straight mouth, nor the three red ears - #no_lens
#no_lens - grey "arcs" too far out, too fuzzy
Oof, long shot. Very fuzzy, not convinced by the shape of that green-yellow sliver at all. #no_lens
So small! So fuzzy! Can't be more than a possible, I think. #gradeC
Hmm - not sure what the red dots are but they don't look very lensed-like. There's a lot of mass there though, so a possible I guess #gradeC
Central object? #no_lens
Possible - but not well defined like lensed features usually are, and so much fuzz! Probably a face on disk galaxy. #gradeC
I see that blue central smudge, but justhink this is a bit too faint to say anything, Still, a possible. #gradeC
#no_lens Even the other one in the top left is not very convincing.
Probably noise bumps fooling our optimistic brains. Curved arclet is too far out for it to be one of a pair. #no_lens
#no_lens - I don't see any sign of a massive deflector galaxy (typically bright yellow/orange), nor of any distorted or magnified features
#no_lens - "arc" is too stratight, too far away, no counter-image, etc
If it's a cusp #arc it's a bit far out, really - and the shape doesn't look quite right. Still, a possible I guess. #gradeC
Nah - no obvious lensed features, for me. #no_lens
Pfuhhhhh #no_lens
Agreed with elisabethB, #no_lens ( #gradeX )
Probably a polar ring galaxy, but can't rule out an Einstein ring instead. #gradeC
I guess if I'm using the 4-point A-B-C-X scale, this one gets a #gradeX from me: definitely not a lens
I don't see much sign of multiple imaging - just a long-ish arclet. I say: just another #gradeC
Hmm - red features are pretty noisy, blue one doesn't show much distortion. It give it a "possible", #gradeC on the A-B-C-X scale
#no_lens - blue clumps look liks SF regions. The galaxy is altogether too fluffy, not like a well defined massive lens-type galaxy.
So I guess it's a singly-imaged "arclet" of a high z dusty galaxy, visible only in the IR (kind of like the SW VICS82 candidates' sources)
In the SDSS image, I don't see any arc at all: http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=183.03690026&dec=13.79253341
That's a nice arc! I like the curvature, but I can't see a counter-image. It could be a "naked cusp" merging triplet, but its quite far out.
Nice arc - but al the rest of that blue fluffy light makes me think its probably a spiral, or a merger with the central object...
Interesting, very red. Good if we could to look at just the z band image here, to see the arc shape better.
Enhance, eh? Wouldn't that be nice? 😉 I'd mark this a #lens for sure. Also a #knownlens! And a pretty interesting one at that...
@kuyanik is making me doubt! 😃 Have added it to my "needs modelling" collection 😃
I vote spiral arms - not enough mass for lensing, and clumps are arranged along spiral arm lines...
I'd bet on those arcs being star formation in tails/arms - but see the discussion for a test of the Cosmic Eye hypothesis
Agree the blue feature is oddly shaped, but suspect artifact not lensing. No sign of a counter-image on the other side either...
Very fuzzy but I like the symmetry of the blue features. Another one that could use a #restretch
Oh NICE! This is a great candidate. Have you seen it before, @c_cld?
I'd guess ring - but it's hard to tell from this picture. It'd be nice to be able to #restretch the image!
Looks like a cluster of galaxies, so lots of mass - but arc is not obvious! Maybe zoom out in skyserver?
What's the angular separation of the two red objects? And the velocity dispersion of the elliptical galaxy? Might not be enough mass...
BTW let's use the hashtag #knownlens for things we know are lenses!
Definitely a lot of dark matter! We've known about this one for a while, but this is the first IR image of it. http://arxiv.org/abs/0902.480
