Top: radio luminosity at 3 GHz for the galaxies that lie within the X-ray groups in the COSMOS field (Gozaliasl et al. 2019) vs. their distance from the group centre, normalised by the virial radius r₂₀₀, for 0.08 ≤ z < 1.53. Bottom: linear projected size D as in Table C.1 vs. distance from the group centre normalised to the virial radius for the same redshift bins as in the panel above. Red colour denotes FRIIs, blue is for FRIs, green denotes FRI/FRIIs, and black is for COM AGN. In both plots the symbol size is proportional to redshift (larger the symbol, larger the redshift). Stars highlight sources that are the brightest group galaxy.
