    #tadpole + #sidelobe? host SDSS J131327.46+315521.3 or something in the background?

    And the NW galaxy SDSS J131327.02+315527.6 has a suspicius blue feature, perhaps a #gravitationallens?

    I would tag this subject as #confused. I think that there is a background source that is confusing with some foreground emission. I don't think that it's a gravitational lens

    Without deeper/higher resolution radio (and IR or optical) observations, I think it's nigh on impossible to figure out what's going on here.

    Except that SDSS J131327.46+315521.3, the blue star-like object, is almost certainly a host; it's a zsp 0.303 QSO. It seems to have a tail, to the NE; perhaps a #NAT? or a #1-sided #jet?

    To the SE is what we'd classify as a #compact if it were on its own. There's no WISE or SDSS source at ~the same position, so if it is an unassociated radio source (e.g. an AGN far in the background), it would be an #IFRS (infrared faint radio source).

    But it's a cool field, no matter what it really is! 😃
