ARG0001rq8, doublelobe, overlap?

  • ChrisMolloy by ChrisMolloy

    Here's ARG0001rq8, which appears to be either a #doublelobe or #triple. The ARG contour overlay below is centred on SDSS J111634.61+291517.1, which is WSW of the ARG co-ordinates listed left. This ARG field is also cross referenced in the post ARG0001rq8 2 galaxy radio source?

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

    The host for the emission appears to be SDSS J111634.61+291517.1, which has a z_sp=0.049 +/-0.00001. This galaxy has radio references in NED and SIMBAD and an ALLWISE reference, ALLWISE J111634.62+291517.0. The spectrum for this galaxy lists it as being #Broadline.

    In terms of the morphology, there is the possibility that these lobes might be #overlapping a background emission. There seems to be a core lobe NE of the host, and other lobe emission NE of the central lobes. There is a radio source NE of SDSS J111634.61+291517.1, SDSS J111635.48+291528.6, which is listed as a star in SDSS DR14, and a galaxy in SDSS DR7. This object has a radio reference in NED. SDSS DR7 cites a z_ph=0.657 +/-0.213.

    The First cut-out below seems to show almost a #halo effect on certain edges of this emission, maybe illustrating the possibility of an #overlap. Although there is always the chance this could be a #restarted emission. Others may have an opinion on this.

    This emission doesn't appear to be imaged in VLASS as yet.

    As always, comments, suggestions, welcome.
