Left panel: Stellar mass of each radio AGN host, M_*^AGN, compared to the mean stellar mass of its control sample, M_*^control. The black dashed line is the 1:1 relation. M_*^control matches M_*^AGN for most galaxies. A few galaxies with only one control galaxy have slightly larger offsets, but our scientific results are not affected. The middle and right panels show similar comparisons for the redshift and 90 percent light radius. Both parameters are also well controlled. We note that the matched M_* and redshift originate directly from the selection criteria in Sect. 3.3, while the matched R₉₀ is the result of the matched angular distance and physical effective radius.
