ARG0000e72, Nat/Wat, two emissions, overlapping?

  • ChrisMolloy by ChrisMolloy

    Here's ARG0000e72, which could be a #Nat or #Wat, and/or possibly two #overlapping emissions.

    First in red.

    The host for the emission appears to be SDSS J160634.96+535337.4, which has a z_sp=0.350 +/-0.00007. This object has radio references in NED and SIMBAD and an ALLWISE reference, ALLWISE J160634.95+535337.3. This galaxy is also cited as being in a galaxy #cluster environment.

    Interestingly, there is recorded First flux emission for SDSS J160634.50+535337.0. This #green galaxy, which is west of SDSS J160634.96+535337.4 has a z_sp=0.343 +/- 0.00002. There doesn't appear to be any radio references cited for this object nor an ALLWISE reference.

    This ARG field has been imaged in VLASS below. The First image tends to show more #diffuse emission to the north, north west, in contrast to the VLASS image.

    As always, comments, suggestions, welcome.

    Yes, this does look like a bent source. I suspect the diffuse Northern emission from FIRST may be image artefacts as the VLASS contours show the NAT/WAT quite clearly.
