ARG0002nk2, two triples?

  • ChrisMolloy by ChrisMolloy

    Here's ARG0002nk2, which appears to be two #triple emissions. This ARG field is cross referenced in the following post: ARG0002nk2 THE 2 RADIO CONTOUR SOURCES?. The contour overlay below is centred on SDSS J104801.60+151521.7, which is west of the ARG co-ordinates listed left.

    The emission centre south could be a #triple, with the host being SDSS J104801.20+151438.4. This galaxy has a z_sp=0.216 +/-0.00003, recorded First flux emission, radio references SIMBAD, and an ALLWISE reference, ALLWISE J104801.20+151438.4.

    Regarding the NE lobe of the centre south emission, there is a a radio reference in NED for SDSS J104802.04+151508.2, which is positioned near its SW edge. This object has a z_ph=0.455 ± 0.1002. Whether this is a distinct separate emission is hard to determine, although there is no ALLWISE reference for this object.

    Regarding the emission to the N, NW, again a #triple, the host for these lobes appears to be SDSS J104759.27+151557.8, which has a z_sp=0.214 +/-0.00004. This galaxy has recorded First flux emission, a radio reference in SIMBAD, and an ALLWISE reference, ALLWISE J104759.29+151558.2. It also appears to be in a #cluster environment. As per the comments in the post: ARG0002nk2 THE 2 RADIO CONTOUR SOURCES?, the morphology for this emission:

    has #core, is #asym, #slipstrike, and likely #restarted or #hybrid (and certainly affected by its environment).

    And here's a VLASS contour overlay for comparison. Contours appear more diffuse.

    As always, comments, suggestions, welcome.

    This is REALLY going to mess up the machine learning algorithms...

    Yes, ML classifications are in its infancy at this point and so human/citizen scientists+science team verification is still vital
