ARG0000iuy - one host a disk galaxy?

    WizardHowl wrote, about this, in the Suggestions for RGZ Objects to show with detailed FIRST contours overlaid on SDSS images thread:

    I would like to suggest for an overlay. As noted initially by antikodon, the emission is messy but to my eye there look to be two galaxies that might be a source of some of the emission: SDSS J130300.80+511954.7 Z_ph~0.14 which is clearly a disk and SDSS J130255.82+511944.6 Z_ph~0.11-0.13 which looks like a barred galaxy.

    In either case, an overlay might help ascertain where the emission is coming from: a wat from a disk galaxy is not something I would have thought possible! (Since a fragile disk would be shredded if it were moving through an IGM capable of bending ultra-relativistic jets to that extent). Even if these are two hourglass/doublelobes, one of them has a very odd radio morphology and there seems to be a radio bridge between them.

    A FIRST contour overlay image, with lots of contours and reaching into the noise, confirms "messy", and "interesting"! 😃 But I'm not sure it helps all that much to decide whether there's one, two, or even more hosts; nor what this/those host(s) might be ...

    Here's the SDSS field without the overlay:
