Abstract

The masses of supermassive black holes correlate almost perfectly with the velocity dispersions of their host bulges, M• / , where = 4.8±0.5. The relation is much tighter than the relation between M• and bulge luminosity, with a scatter no larger than expected on the basis of measurement error alone. Black hole masses estimated by Magorrian et al. (1998) lie systematically above the M• - relation defined by more accurate mass estimates, some by as much as two orders of magnitude. The tightness of the M• - relation implies a strong link between black hole formation and the properties of the stellar bulge (Refer to PDF file for exact formulas).
