Radio core luminosity vs. the galaxy stellar masses for the Virgo sample analyzed in Capetti et al. (2009). The four galaxies of interest are labeled with their Messier or NGC numbers. The radio detected galaxies are marked with large circles, separating them on the basis of the optical surface brightness profiles: filled circles are CoreG, while empty circles are pure SG. The undetected objects are marked with small squares (for clarity, we omit the downward pointing arrows), empty for SG, filled for CoreG.
