ARG0001wa6, host? morphology?

  • ChrisMolloy by ChrisMolloy

    Here's ARG0001wa6, which appears to be an #extended, radio emission. This ARG field is cross referenced in the post ARG0001wa6 GALAXIES NORTH z 0.099 & SOUTH 0.098 the radio contour sources?

    The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk
    First in red.

    A possible host for the emission could be SDSS J075917.10+270916.0, which has a z_sp=0.099 +/- 0.00001. This galaxy has radio references in NED and SIMBAD, and an ALLWISE reference, ALLWISE J075917.10+270916.0. This galaxy is also the brightest galaxy in a #cluster.

    There are a number of other radio references for these lobes in NED and SIMBAD. Whether any of these is the host of the emission is hard to determine. As for the morphology of these lobes, either slightly #s-shaped, #restarted, or two or more emissions with separate hosts, is hard to ascertain. Others may have an opinion on this.

    First cut-out below.

    As always, comments, suggestions, welcome.

    Very, very cool! 😃

    I think your overlay makes an excellent case for this being an #overlap: there are two hosts, both #core:

    The obvious one is SDSS J075917.10+270916.0.

    The less so is SDSS J075916.37+270914.7, which has no SDSS zsp or zph (!), and nothing in NED:

    But which lobes belong to which host? I have no idea.

    It's also possible this is a #restarted #triple (host SDSS J075917.10+270916.0) and a faint #compact (host SDSS J075916.37+270914.7).
