    First in red.

    The host for the centre emission appears to be SDSS J102714.83+460256.8, which has a z_sp=0.526 +/- 0.00003. This galaxy has radio references in NED and SIMBAD, and an ALLWISE reference, ALLWISE J102714.81+460256.4. It is cited as being an #AGN, has recorded First flux emission, and does seem to have emissions that are #overlapping. As per the ARG comments left, this emission is what is:

    known as a "double-double" source. So you are seeing 2 episodes of activity in this radio AGN.

    The #compact lobe to the west appears to be positioned on SDSS J102710.48+460255.1. This object has a z_ph=0.464 ± 0.1463, and recorded First flux emission. There doesn't appear to be any radio references in NED or SIMBAD for this galaxy, nor an ALLWISE reference.
