Title: The massive black hole at the center of the Milky Way
Abstract:
I report new observations with the ESO VLT on the stellar dynamics and distribution in the central parsec of the Galaxy. For the first time, it is now possible to determine stellar obits and make a precision determination of the gravitational potential to a scale of ten light hours. These data and recent radio and X-ray observations provide the best evidence we have that the compact radio source SgrA* must be a supermassive black hole and give detailed information on the environment around the hole. I will also discuss the very recent discovery of infrared flares from SgrA* providing strong evidence that the black hole must be rotating.
