A possible gravitational lens candidate in SDSS ?

• by Dolorous_Edd

  The source of radio emission in this ARG field is SDSS J162300.35+213722.3 / SDSS J162300.29+213720.5

  Post about it in Galaxy zoo Talk

  A z_sp = 0.758 merger with sort of arc around it

  Arc is mostly visible in SDSS r-band and SDSS g-band

  

  FIRST/SDSS overlay, host seems to be SDSS J162300.29+213720.5 ( core + lobes )

  

  Could this be a gravitational lens or this just chance aligment of galaxies?

  Just FYI - Dr Phil has responded to you thread over on GZ Talk regarding this object 😃

  It is nice to see Dr Phil so cautiously excited.

  Thanks for heads up!

  Adding to GZ, please find a stack of three SDSS frames of the location

  

  and a zoom in

  

  I wonder if there are two purple opposite jets from this (AGN?) radio galaxy?

  Just for fun, here's my FIRST/SDSS contour overlay:

  

  Certainly a somewhat unusual radio morphology ...

  The image in this post was created from sources, and using methods, described in this RGZ Talk post. The object at the center of the image is SDSS J162300.35+213722.3
