Possible Lens: Ukidds vs SkyServer Image (from Galaxy Zoo)

• by jedkat

  

  Hi all,
  I came cross this image from galaxy zoo and it was suggested I post here for further study:

  That's very neat, @jedkat - definitely a possible lens candidate, just from glancing at it. Redder colors (as we see in the UKIDSS images) are possible lenses. I'd suggest maybe cross-posting a screenshot of this on the SpaceWarps Talk and see what the experts there have to say.

  obviously this is a ukidds image. I looked this picture up in skyserver and could not find any indication of lensing or an arc, but in infrared it does look to have some features. Any help would be appreciated

  Here is the skyserver link:

  thanks!

  Not an expert, but here goes :

  It looks interesting in infrared, wish we could take a look at it in Tools.
  That said I'm not convinced it is a lens.If I got this to classify (in infrared or optical) I'd probably classify this as a fuzzy spiral.

  Anyone else ?

  I'm not sure how this looks like a lens. To me, it looks like a galaxy with a bright nucleus, and some red galaxies shining through but don't look lensed. Am I missing something?
