AbstractI use the fact that the radiation emitted by the accretion disk of supermassive black hole can heat up the surrounding gas in the protogalaxy to achieve hydrostatic equilibrium during the galaxy formation. The correlation between the black hole mass M (BH) and velocity dispersion sigma thus naturally arises. The result generally agrees with empirical fittings from observational data, even with M (BH) a parts per thousand currency sign10(6) M (aS (TM)). This model provides a clear picture on how the properties of the galactic supermassive black holes are connected with the kinetic properties of the galactic bulges.
