    This image has two candidates! top center and center left! The top one flagged up as simulated, but is the left one real (I don't know!)

    #sim on center top. but nice catch for the second one! I think this is one of the systems which is a very good candidate!

    If it isn't simulated, I'd bet my house on the second one being a real lens

    second one looks good to me!. nice arc there.

    Isn't that cool? @c_cld spotted that one by chance while we were developing the website - it's a great candidate

    We looked at it with the Keck telescope in December and, crazy as it seems, it looks like those arcs are part of the yellow galaxy!

    @gumbosea has a Letter coming out on this system very soon - he shows that its really well fitted by a #lens model

    It's just the spectrum that's weird! Or nature: honestly, this is the most lens-like non-lens I have ever seen (if it is indeed not a lens)

    @drphilmarshall can't agree more

    Do you have a redshift for the blue feature? (if the yellow and blue are at the same redshift they are the same distance, so not a lens)

  • drphilmarshall by drphilmarshall scientist, admin

    Exactly, that's the result: we see emission lines but at the lens redshift. Now, that doesn't mean there couldn't be a zs > zd as well...

    Sim top right of center, possible lens lower left edge

    double #lenses

    agreed. #simulation at 12 o'clock, and probable #lens at 8 o'clock

    left edge better seen in ASW0000we9
