"Gamma-Ray Emission from AGN and Radio Galaxies"

Abstract. In the last couple of years, radio galaxies have emerged as a new gamma-ray emitting source class on the extragalactic sky. Harboring jets that are substantially inclined with respect to the observer, their appearance is not much affected by relativistic Doppler boosting effects. As such they offer the unique potential to probe some of the fundamental physical processes in Active Galactic Nuclei that appear otherwise masked in classical blazar-type sources. I will highlight some of the key questions in the field, discuss the relevance of the observed gamma-ray characteristics and, taking the archetypal M87 as an example, report on the theoretical progress achieved within recent year.
