Description
Masses of supermassive black holes (SMBH) are known to correlate with the spheroidal component of their host galaxies according to the so-called M-sigma (Magorrian) relation. A further proposal of a correlation between the SMBH mass and halo mass is a focus of research. In this talk, we propose a mechanism for the co-evolution of black holes and their host dark matter haloes based on the hydrodynamics of accretion flow. We find that the massive haloes above a transition halo mass will be able to grow black holes to achieve a constant ratio between the hole and halo mass that agrees with the proposed black-hole and halo mass relation. Haloes below the transition halo mass would host black holes smaller than expected from the black-hole mass halo mass relation. We also compare our results with observations and find a good agreement.
