2000ApJ...539L..13G A Relationship between Nuclear Black Hole Mass and Galaxy Velocity Dispersion Karl Gebhardt, Ralf Bender, Gary Bower, Alan Dressler, S. M. Faber, Alexei V. Filippenko, Richard Green, Carl Grillmair, Luis C. Ho, John Kormendy, Tod R. Lauer, John Magorrian, Jason Pinkney, Douglas Richstone, and Scott Tremaine Received 2000 June 2; accepted 2000 June 29; published 2000 August 3 ABSTRACT We describe a correlation between the mass M_bh_ of a galaxy's central black hole and the luminosity-weighted line-of-sight velocity dispersion {sigma}_e_ within the half-light radius. The result is based on a sample of 26 galaxies, including 13 galaxies with new determinations of black hole masses from Hubble Space Telescope measurements of stellar kinematics. The best-fit correlation is M_bh_ = 1.2(+/-0.2)x10^8^ M_sun_({sigma}_e_/200 km s^-1^)^3.75 (+/-0.3)^ over almost 3 orders of magnitude in M_bh_; the scatter in M_bh_ at fixed {sigma}_e_ is only 0.30 dex, and most of this is due to observational errors. The M_bh_-{sigma}_e_ relation is of interest not only for its strong predictive power but also because it implies that central black hole mass is constrained by and closely related to properties of the host galaxy's bulge.
