ARG0001llw, wat/nat, host?

  • ChrisMolloy by ChrisMolloy

    Here's ARG0001llw, which appears to be a #wat or a #nat.

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

    The host for this emission seems to be SDSS J072310.17+321003.1, which has a z_ph=0.600 ± 0.0698. There appears to be radio references for this host and its emissions in NED and SIMBAD, and it has an ALLWISE reference, ALLWISE J072310.11+321003.1.

    SDSS J072310.17+321003.1

    As per the classification comments left, and this emission being from one, two, or three distinct hosts, there doesn't appear to be any other photometric objects in alignment with the lobes, with the exception of SDSS J072310.17+321003.1.

    As always, comments, suggestions, welcome.

    If you ignore the relatively diffuse radio emission streaming N from the E ~point-source, and S from the W one, I think this would look like a fairly normal #triple, with host SDSS J072310.17+321003.1 (albeit somewhat asymmetric).

    So perhaps this is a #restarted, with the ~N and ~S "lobes" the remnants of an older eruption? It too would have been asymmetric. If so, that's some pretty dramatic change in the apparent axis! 😮
