The mø-σ relation for supermassive black holes.

MERRITT D. and FERRARESE L.

Abstract (from CDS):

We investigate the differences in the Mø-σ relation derived recently by Ferrarese & Merritt and by Gebhardt and collaborators. The shallower slope found by the latter authors (3.75 vs. 4.8) is due partly to the use of a regression algorithm that ignores measurement errors and partly to the value of the velocity dispersion adopted for a single galaxy, the Milky Way. A steeper relation is shown to provide a better fit to black hole masses derived from reverberation mapping studies. Combining the stellar dynamical, gasdynamical, and reverberation mapping mass estimates, we derive a best-fit relation Mø=1.30(±0.36)x108 Mc/200 km.s–1)4.72(±0.36).
