    On the top of the image: SDSS ID 1237667915420270731 QSO z=2.981
    SDSS ID 1237667915420271100 QSO z=0.421 (BOSS spectrum)
    SDSS ID 1237667915420271090* AGN z=0.424

    Is the QSO z=0.421 a Radio Quasar? Is the AGN interacting with the QSO, which has same redshift?

    When images are put a the same scale, the only overlap with QSO is for the very faint intermediate one (low flux in optical, minor detail in radio).

    To me, no #bhgroup but amazing #Xshaped
