ARG0001rxz - possible distant lobes?

• by JeanTate

  Here's an contour overlay, FIRST and NVSS on SDSS; wishful thinking or real lobes (or at least one)?

  

  SDSS J170026.60+290928.9, z_ph 0.720 ± 0.1189/0.571 ± 0.2695:

  

  Boilerplate: SDSS image per http://skyservice.pha.jhu.edu/DR10/ImgCutout/getjpeg.aspx, FIRST (red) and NVSS (cyan) contours derived from FITS files produced using SkyView with Python code described in this RGZ Talk thread. Image center per the ARG image (left; J2000.0). "z_ph" is an SDSS photometric redshift of the galaxy in the center.

  This is a nice example of why this can be really hard to do.

  I would say that the source in the lower left of the top image (SE) is not related to the central radio source. The reason for this is that if you look closely at the red radio contours of the source in the bottom left you will see that it points to the lower left and not towards the central object.
