Massive Black Holes in Galactic Nuclei — •Reinhard Genzel — Max-Planck-Institut für extraterrestrische Physik, Garching, Germany

Do massive black holes exist? What is their importance in the Universe? Ever since the discovery of quasars forty years ago the evidence for massive black holes in galaxy nuclei has steadily grown. In the past few years high resolution infrared imaging and spectroscopy have given compelling evidence for the presence of compact mass concentrations in the nucleus of the Milky Way as well as a near active galaxy; any configuration of the central mass other than that of a Black Hole is virtually excluded. This evidence will be discussed as well as our present understanding how such black holes have formed and evolved in the early Universe.
