ARG0002evo, one or two emissions, SDRAGN candidate, overlap?

  • ChrisMolloy by ChrisMolloy

    Here's ARG0002evo, which appears to be either an #extended, emission, possibly a #triple, or a #doublelobe and a #overlapping #compact. The contour overlay below is positioned on SDSS J142616.10+190339.1, which is south of the ARG co-ordinates listed left.

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

    If some of this emission is a #doublelobe then the host would be SDSS J142616.10+190339.1, which is a #green galaxy and has a z_ph=0.144 ± 0.0692. This object is positioned in the centre of the lobes, and has radio references in NED and possibly SIMBAD. The SIMBAD reference is slightly west of this galaxy. There appears to be an ir sources at the position of this galaxy, but there is no ALLWISE reference for this.

    In terms of this galaxy being an #SDRAGN candidate, it has a fracDev_g, _r, of 0.254 and 0.509; and an expAB_g of 0.621and expAB_r of 0.629 respectively. For c, the inverse concentration index, it has a figure of 0.356 for the g band and 0.396 for the r band. Possibly this could be a #disk galaxy and an #SDRAGN candidate. Others may have a view on this.

    To the south of SDSS J142616.10+190339.1 is what appears tp be a #compact lobe positioned on SDSS J142616.25+190329.1. This object is cited as a #star, has recorded First flux emission, and an ALLWISE reference, ALLWISE J142616.26+190329.4. As per the ARG comments left, this object could possibly be a #QSO. If this is one emission, then this object would be the host of a #triple.

    This ARG field has not been imaged in VLASS as yet.

    As always comments, suggestions, welcome.

    No doubt that the blue star, likely a QSO, is a host. But is it the only host? I think it's possible there's a second host, with at least one lobe, and that it's possibly a disk galaxy. So yes, an #sdragn candidate! Yay! 😃
