ARG0000hv6, one, two, or three emissions.

  • ChrisMolloy by ChrisMolloy

    Here's ARG0000hv6, which appears to possibly be either one, two, or three emissions. This ARG field is cross referenced in the ARG0000hv6 Group of galaxies with radio contours post.

    First in red.

    The extended lobe to the east is centred on SDSS J094111.17+515010.7, which has a z_ph=0.338 ± 0.0793. This galaxy has a radio reference in NED, and an ALLWISE reference, ALLWISE J094111.14+515010.8.

    The central, almost round like emission, appears to be positioned on SDSS J094109.49+515010.8, which has a z_sp=0.348 +/- 0.00011. This galaxy again has a radio reference in NED, and an ALLWISE reference, ALLWISE J094109.46+515010.9.

    And finally, the small #core-jet like lobe to the west, is centred on SDSS J094108.07+515001.7, which has a z_sp=0.350 +/- 0.00007. This galaxy has recorded First flux emission, but no apparent radio references in NED nor Simbad. However, there is an ALLWISE reference, ALLWISE J094108.05+515001.8.

    Whether these emissions are one, two, or three separate lobes, is hard to discern. The dissimilar morphologies of each lobe does not help this question; with the east lobe being extended, the central lobe almost round, and the west lobe verging on being a small #core-jet. Possibly these variants are accentuated by the emissions being in a #cluster, #group environment.

    As always, comments, suggestions, welcome.
