Abstract:Radio galaxies produce the most energetic phenomena in the Universe. They are associated with giant elliptical galaxies hosting the most massive black holes (>10^8 solar masses). In the local Universe the optical classification of radio galaxies reflect a clearer separation in nuclear and host properties than that based on the radio morphology. I will summarize my past results on local radio galaxies which show global evidence for co-evolution of black holes and host galaxies. Our knowledge on local radio galaxies provides the key to understand my new results on distant radio galaxies (0.7 < z < 3) selected in the COSMOS field.
