    Here's ARG0000kam, which appears to be an #hourglass.

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

    A possible host for the emission appears to be SDSS J095520.51+503407.9, maybe a disk galaxy, which has a z_ph=0.246 ± 0.0285, and recorded First flux emission. This object doesn't appear to have any radio references in NED or SImbad, but does have an ALLWISE reference, ALLWISE J095520.59+503408.1. This object is also more centred on the west lobe of the #hourglass.

    As to whether this object is a disk galaxy, and possibly an #SDRAGN candidate, it has a fracDev_g, _r, of 0.485, and 0.032; and an expAB_g of 0.392 and expAB_r of 0.480 respectively. For c, the inverse concentration index, it has a figure of 0.516 for the g band and 0.453 for the r band. On the above parameters, if this object is the host, it could possibly be an #SDRAGN candidate.

    Interestingly, there are radio references in NED for SDSS J095520.51+503413.2, which is listed as a star, and has an SDSS DR6 z_ph=0.444 +/-1.219. There doesn't appear to be any other radio references for this object, which is centred slightly north of SDSS J095520.51+503407.9. Whether this object is the host of the emission is hard to discern.
