  The observed Tully-Fisher and Faber-Jackson laws between the baryonic mass of
galaxies and the velocity of motion of stars at the edge of galaxies are
explained within the framework of the model of accretion of galaxies around
supermassive black holes (SMBH). The accretion model can also explain the
M-sigma relation between the mass of a supermassive black hole and the velocity
of stars in the bulge. The difference in the mechanisms of origin of elliptical
galaxies with low angular momentum and disk galaxies with high angular momentum
can be associated with 3D and 2D accretion.
