ARG00014le, wat?

  • ChrisMolloy by ChrisMolloy

    Here's ARG00014le, which could be a #doublelobe #hourglass centre, and a #compact lobe to the west. This emission could also possibly be a #wat.

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

    The host of these emissions is hard to determine, due to it being in a #cluster environment.

    There are a number of radio references in NED for SDSS J143816.26+403539.5, which has a z_ph=0.553 ± 0.0864. This galaxy is positioned at the eastern edge midpoint of the centre emission.

    There are radio references in NED and possibly SIMBAD, for SDSS J143814.57+403531.5, which has a z_ph=0.282 ± 0.0306. This object has an ALLWISE reference, ALLWISE J143814.59+403531.5. The SIMBAD reference is on the north edge of this galaxy. If this object is the host of the emission, as it is positioned in between both lobes, it could be a #wat.

    There is also a radio reference in NED for SDSS J143815.82+403534.2, which is positioned in the middle of the centre southern lobe. This galaxy has a z_ph=0.267 ± 0.0274. This object could also be the host of a #wat, or a #one-sided #doublelobe or #hourglass.

    Regarding the possible #compact lobe, there is a radio reference in SIMBAD which is positioned in the centre of this emission, which is to the west of SDSS J143813.32+403523.5. This galaxy has a z_ph=0.250 ± 0.0173, and an ALLWISE reference, ALLWISE J143813.44+403524.1. Whether this is a distinct #compact lobe is hard to determine.

    This ARG field hasn't been imaged in VLASS as yet.

    As always, comments, suggestions, welcome.

    Nice work! 😃

    Too many galaxies, not enough radio resolution -> very difficult to determine which might be the host(s) ...
