    ACTIVE GALACTIC NUCLEI AND BLACK HOLES.  AGN phenomenology, optical, radio and X, including superluminal motions, BPT diagram. Eddington luminosity, accretion rate, time. Unified model for AGN, Radiative efficiency of an accretion disc. Proofs of BH existence: variability, iron line, motion of S2 around SgrA*, EHT. Remnant BHs: scaling relations, Soltan argument, BH mass function, BH seeds and their formation scenarios.  Role of AGNs in galaxy evolution (hints).

    RADIO GALAXIES. Properties: size and structure, classification (FRI and FRII), Lradio-Lopt, HERG/LERG vs. RE/RI. Physical processes: syncrotron radiation and energy equipartition, steepening of the spectrum and spectral index maps, age of the lobes, X-ray and synchrotron self-inverse Compton radiation, polarization and rotation measure, RG cycle.  Host-galaxies.  Environment: NAT and WAT, RGs in cool core clusters. Confinement. Fuelling. Feedback: cavity and relation with ICM. Diffuse emission properties: occurence, size, location and cluster types, spectra and polarization, classification (halos,relics Gischt/Phoenix, mini halos). Radio-X relation. Radio "bimodality". Magnetic fields (hints). Reacceleration models and merger shock/turbulence.  Hadronic models.
