L_150 MHz of radio AGNs versus the ϵ and λ_Re of their host galaxies. The top panels show the L_150 MHz of radio AGNs as a function of the ϵ of the host galaxies in three M_⋆ bins (from left to right): log(M_⋆/M_⊙) = 11.2 − 11.5, 11.5 − 1.8, and > 11.8. The bottom panels show the L_150 MHz as a function of the λ_Re of the host galaxies in three M_⋆ bins. In all panels, the blue points denote radio AGNs from M22, and the red points denote radio AGNs from the BH12 sample.
