Summary
Active galaxies and their innermost core regions show extreme physical processes. In the vicinity of a supermassive black hole they produce an enormous amount of energy output and often also high-energy gamma-ray photons at MeV/GeV energies. Many of the physical processes are so far not understood in detail, e.g. the production of their highly relativistic jets or the origin of the gamma-ray emission as well as the observed variability across the whole electromagnetic spectrum. New instruments and observing programs allow now to obtain new insights into the extreme physics of these objects.
