ARG0000xqx - overlap? or lens

• by Dolorous_Edd

  Is that an overlap or there could be possible lensing? Personally, I think it is an overlap

  SDSS J115617.02+435515.0 - 1237661849856966743

  Has z_sp = 0.071

  

  Nearby, SDSS J115616.89+435512.8 has z_sp = 0.133

  SDSS J115616.89+435512.8 - 1237661849856966747

  Cool! 😃

  I think it's more likely an #overlap than a grav lens; the morphology of the blue object is not like that of a lensed galaxy IMHO.

  The spectrum of the blue object has lots of lines/features of the foreground galaxy, particularly the absorption lines H&K, G, Mg, and Na D.
