2004ApJ...604L..89H On the Black Hole Mass - Bulge Mass Relation Nadine Haring and Hans-Walter Rix Abstract. We have reexamined the relation between the mass of the central black holes in nearby galaxies, M_bh_, and the stellar mass of the surrounding spheroid or bulge, M_bulge_. For a total of 30 galaxies bulge masses were derived through Jeans equation modeling or adopted from dynamical models in the literature. In stellar mass-to-light ratios, the spheroids and bulges span a range of a factor of 8. The bulge masses were related to well-determined black hole masses taken from the literature. With these improved values for M_bh_, compared to Magorrian et al., and our redetermination of M_bulge_, we find that the M_bh_-M_bulge_ relation becomes very tight. We find M_bh_~M^1.12+/-0.06^_bulge_ with an observed scatter of <~0.30 dex, a fraction of which can be attributed to measurement errors. The scatter in this relation is therefore comparable to the scatter in the relations of M_bh_ with {sigma} and the stellar concentration. These results confirm and refine the work of Marconi & Hunt. For M_bulge_~5x10^10^ M_sun_ the median black hole mass is 0.14%+/-0.04% of the bulge mass. Keywords: Galaxies: Bulges, Galaxies: Kinematics and Dynamics
