ARG00007ee, overlapping, extended, emissions, hosts?

  • ChrisMolloy by ChrisMolloy

    Here's ARG00007ee, which appears to be a very extended emission. As per the ARG comments left, it could be a #triple, #overlap, #hybrid, with a #compact emission at the WSW north edge. There could also be multiple emissions and hosts in this ARG field.

    First in red.

    A host for one of the WSW emissions, which could be a #triple, is SDSS J114250.35+580759.8, which has a z_sp=0.377 +/-0.00003. This object has recorded First flux emission, radio references in NED, is listed as a #QSO Broadline, and has an ALLWISE reference, ALLWISE J114250.35+580759.8.

    Regarding the possible overlapping emission, to the SW, of SDSS J114250.35+580759.8 there are radio references in NED for SDSS J114250.03+580753.8, which is listed as a #star. This object also appears to possibly have radio references in SIMBAD, although this reference is slightly west of SDSS J114250.03+580753.8. There doesn't appear to be an ALLWISE citation at this location.

    There is also a radio reference in NED for SDSS J114249.52+580757.8. This object has a z_sp=0.377 +/-0.00003. Whether this galaxy is the host of any of the WSW emissions is hard to determine. Of note, SDSS DR15 cites this object as a star, but its spectrum lists it as a #starburst galaxy.

    The #compact lobe on the WSW north edge is positioned on SDSS J114248.13+580759.6. This object has a z_ph=0.302 ± 0.0410, and an ALLWISE reference, ALLWISE J114248.13+580759.6. There doesn't appear to be any radio references in NED nor SIMBAD for this galaxy.

    Concerning the central emission, if it is not related to the WSW lobes, there is a radio reference in NED for SDSS J114252.21+580814.6, which has a z_ph=0.066 ± 0.0250. This object has an ALLWISE reference, ALLWISE J114252.22+580814.1, and is positioned near the north edge of this lobe.

    Regarding the emission to the east, it appears it could be related to the central, WSW emissions, and hosts. However, there is a radio reference in NED for SDSS J114254.26+580813.3, which has a z_ph=0.423 ± 0.0681.

    And finally, there is always the possibility that the host for the east lobe could be SDSS J114255.64+580821.6. This object is listed as a #star, and has an ALLWISE reference, ALLWISE J114255.63+580821.5.

    Here's a VLASS image of this ARG field. The emission contours are less connected in the east, than in the First overlay image.

    As always, comments, suggestions, welcome.

    Complex!

    Two hosts are, well, not exactly obvious but with VLASS, clear.

    Whether the bright star is also a host is ... intriguing! 😃
