Possible lens at lower left. The sim is at top right of center

@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)

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

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