ARG0003e29, hourglass or wat, gravitational lens, SDRAGN candidate?

  • ChrisMolloy by ChrisMolloy

    Here's ARG0003e29, which appears to be either a #wat or an #hourglass, with an unusual curvature. The contour overlay below is centred on SDSS J162132.36+060719.1, 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.

    The host for the emission is SDSS J162132.36+060719.1, which has a z_ph=0.350 ± 0.0164, and an NED z_sp=0.343. This object has radio references in NED and SIMBAD and an ALLWISE reference, ALLWISE J162132.39+060719.3. This galaxy is cited as being the brightest galaxy in a #cluster (BCG), and also has #gravitational-lens citations in NED and SIMBAD. This object is listed and imaged in the following paper: Gemini/GMOS Spectroscopy of 26 Strong Lensing Selected Galaxy Cluster Cores. This galaxy could also be #disk like in morphology.

    In terms of the morphology of this galaxy, and whether it could be an #SDRAGN candidate, it has a fracDev_g, _r, of 1 and 1; and an expAB_g of 0.768 and expAB_r of 0.919 respectively. For c, the inverse concentration index, it has a figure of 0.416 for the g band and 0.343 for the r band. On these figures, possibly not a #disk galaxy or #SDRAGN candidate. Others may have a view on this.

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

    As always, comments, suggestions, welcome.
