Title: Super-Massive Black Holes: The Missing Link in Galaxy Evolution

***********************************************************
Abstract: Spectroscopic and photometric studies of the stellar and gas dynamics in the very central regions of most local spheroidal galaxies and prominent bulges have revealed the presence of a Super-massive black hole (SMBH) at their center, tightly linked with the mass and dispersion velocity of host galaxy. How and why SMBH have become so closely linked with their host galaxies and possibly with the whole surrounding Dark Matter (DM) halo? Starting from SMBH and AGN demography I will derive the basic features of SMBH accretion. I will then use Granato et al. (2004) model to show how the mutual feedback between SMBH and stars can account for the tight link between SMBH and galaxy and reproduce the AGN statistics. Finally I will show that all the previous model-dependent results on baryon/SMBH evolution in DM halos, can be directly inferred from detail analysis of the local data.
