Black Holes: Formation, Quasars: Evolution
Scientific paper
Recent high-quality observations have revealed that the mass of a supermassive black hole (SMBH) tightly correlates with that of a galactic bulge. However, little has been elucidated regarding the physics on the angular momentum transfer in a spheroidal system (a bulge), which is inevitable for the formation of BHs. Here, a potential mechanism to build up a SMBH is proposed by using the angular momentum transfer due to a radiation drag. In the present model, the mass of a SMBH is predicted to be in proportion to the bulge mass, and it turns out that the SMBH-to-bulge mass ratio is basically determined by the nuclear energy conversion efficiency from hydrogen to helium (=0.007). In the present context for a SMBH growth, we construct a new QSO formation scenario.
