Title : Hypermassive Black Holes in the Universe
Abstract : The possible existence of black holes (BHs) in the Universe is an important theoretical prediction of Einstein's theory of general relativity since 1916. Astronomers and astrophysicists have been collecting more and more evidence for detecting BHs (stellar mass BHs, intermediate mass BHs, supermassive BHs, and hypermassive BHs). The emphasis here is mainly on the formation of intermediate BHs in globular clusters and supermassive BHs in galactic bulges/elliptical galaxies as well as on the possibility of hypermassive BHs (10 to 1000 billions of solar masses) at the center of very massive galaxy clusters. In particular, the empirical M-sigma relation (between the central BH mass and the mean velocity dispersion of the host bulge) is derived in the framework of spherical hydrodynamic collapse.
