neat radio spiral

    strong point source with a cool spiral. hard to see on wise. must be really far away.

    The core/host - the central object in this triple - is at the same location on the sky (plus or minus a pixel or three) as SDSS J123136.17+285026.7, which the SDSS photometric pipeline classes as a STAR. It's possible, even likely, that this is, in fact, a distant galaxy, with a redshift of at least 0.5 (judging by its gri SDSS colors). here's the field centered on it:

    I think the faint green smudge apparently 'coming from' this is an artifact, but it may not be.

    The 'spiral helicopter' is SDSS J123134.72+284948.4, an Eos (edge-on spiral; my term), spectroscopically classed as STARFORMING (the spectrum has strong emission lines). Its redshift (z) is 0.064, which makes it quite 'local', here in RGZ 😮 I don't think it has anything to do with the radio source, other than being a chance alignment.

    Neat. Yeah the fact it was just a tiny pixel made it hard for me to interpret.
