At z = 0.533 a red galaxy is also a radio source. I am guess that comes from an AGN or something?
The radio source in Simbad is not this these galaxies - see how it says " Distance to the center arcsec: 35.93"?
If you flip to the VLASS 1.2 image layer, you’ll see the radio source they’re talking about – no optical counterpart.
