``Outbursts from Supermassive Black Holes in Clusters of Galaxies and the Problem of Galaxy Formation''

The nuclei of giant galaxies located at the centers of galaxy clusters harbor billion solar mass black holes. These black holes and their host galaxies grow by accreting gas. The gravitational binding energy released by the inflowing gas regulates the growth of the black holes and the giant galaxies that harbor them. This situation mirrors the more general problem of baryon cooling and galaxy formation in the Universe.

Refreshments will be served in CP 155 at 3:15 PM
