ARG0001mrt, x-shaped lobes, more than one host and emission?

  • ChrisMolloy by ChrisMolloy

    Here's ARG0001mrt, which appears to be an #unusual emission. In terms of morphology, it appears #x-shaped, possibly a #triple or #doublelobe, a #wat, #overlapping lobes, and or one or more emissions. The contour overlays below are centred on SDSS J133437.35+313617.4, which is SSW of the ARG co-ordinates listed left.

    A possible host for some of the emission could be SDSS J133437.35+313617.4, which has a z_ph=0.182 ± 0.0311. This object has radio references in NED, and an ALLWISE reference, ALLWISE J133437.35+313617.3. This galaxy is SW of the centre of the emission.

    There is a radio reference in NED for SDSS J133439.31+313618.5, which has a z_sp=0.196 +/-0.00003. This object has an ALLWISE reference, ALLWISE J133439.33+313618.3. This galaxy is positioned ESE of the centre of the lobes.

    There are a number of other radio references in NED and SIMBAD for these lobes, but what could be a host or hosts is hard to determine. As per the ARG comments left, this could be an

    unstudied, WAT or relic-type src?

    In terms or morphology, it could also be a #doublelobe or #triple along the SW and NE axis, and maybe a #doublelobe or #triple along the W to E axis, but again. this is hard to ascertain. Also, this ARG field appears to be in a #cluster environment.

    Here's a VLASS contour for comparison.

    And for completeness, here's a First Wise Band 1 contour overlay.

    As always, comments, suggestions, welcome.

    Apart from SDSS J133439.31+313618.5 being a (the?) likely host, there's not much that's clear for this #weird source. Obviously near the center of a rich, dense cluster of galaxies, so perhaps the complicated IGM (inter-galactic medium) is partly responsible? And the ISM (inter-stellar medium) of at least one galaxy too (SDSS J133437.35+313617.4), if it's foreground to the radio emission.
