    The "STAR" - z_sp 0.211 SDSS J075819.68+421935.1 - is actually an AGN, the nucleus of a galaxy in the process of merging; what an incredible spectrum! No wonder NED lists 43 references.

    Is this the host of a bent doublelobe? Or are those two not-quite-like-lobes radio source unrelated?

    And what's at the bottom (S)? Another merger, with extended NVSS emission? 😮 Worth looking into ... 😃

    Boilerplate: SDSS image per http://skyservice.pha.jhu.edu/DR10/ImgCutout/getjpeg.aspx, FIRST (red) and NVSS (cyan) contours derived from FITS files produced using SkyView with Python code described in this RGZ Talk thread. Image center (J2000.0) is the galaxy SDSS J075819.68+421935.1; "z_sp" its SDSS spectroscopic redshift.

    SDSS J075814.39+421607.1 is the larger of the red spirals; both have SDSS z_sp 0.032 (neither spectrum resembles an E+A object):

    The nucleus of the smaller galaxy, SDSS J075815.13+421607.2, seems to be a faint radio source (per FIRST); the combined object has a curious NVSS morphology:

    Faded/fading jet? Almost a relic?

    The nearby pair of galaxies is in Bill Keel's sample of overlapping galaxies from Galaxy Zoo! 😃
