ABSTRACT
Using results from structural analysis of a sample of nearly 1000 local galaxies from the
Sloan Digital Sky Survey, we estimate how the mass in central black holes is distributed
amongst elliptical galaxies, classical bulges and pseudo-bulges, and investigate the
relation between their stellar masses and central stellar velocity dispersion . Assuming
a single relation between elliptical galaxy/bulge mass, MBulge, and central black hole
mass, MBH, we find that 55+8
-4 per cent of the mass in black holes in the local universe
is in the centres of elliptical galaxies, 41+4
-2 per cent in classical bulges and 4+0.9
-0.4
per cent in pseudo-bulges. We find that ellipticals, classical bulges and pseudo-bulges
follow different relations between their stellar masses and , and the most significant
