    FIRST on SDSS ( red dots are SDSS photometric objects )

    More likely SDSS J131259.58+450531.9 is the host of this
    hourglass, though I would be glad to be wrong

    I would be inclined to say that the red circle at the centre of the radio contours in the above image is the counterpart and not the sprial galaxy. Others may disagree with me though.

    FROM NED FOR EACH GALAXY. IS EACH GALAXY A RADIO SOURCE? IS SDSS J131259.58+450531.9 THEN THE ONE?

    As a radio astronomer working on radio galaxies on daily basis I do agree with @42jkb

    The spiral is just a edge coincidence (it's not even in a right place to be able to produce the radio emission)

    Perhaps the z_sp 0.035 inclined spiral SDSS J131259.48+450549.6 has nuclear radio emission, and there's an unrelated doublelobe far in the background?

    Perhaps the doublelobe's host is z_ph 0.753±0.0787/0.640±0.1389 SDSS J131259.58+450531.9:

    If so, I wonder if a detailed study of the doublelobe's emission might say something interesting about the ISM (interstellar medium) in the foreground spiral?

    Boilerplate: SDSS image per http://skyservice.pha.jhu.edu/DR10/ImgCutout/getjpeg.aspx, FIRST (red) contours derived from the FITS file produced using SkyView with Python code described in this RGZ Talk thread. Image center (J2000.0) is the galaxy SDSS J131259.48+450549.6; "z_sp" its SDSS spectroscopic redshift.
