Masses of Black Holes in Active Galactic Nuclei
Abstract
Description
We present a progress report on a project whose goal is to improve both the precision and accuracy of everberation-based black-hole masses. Reverberation masses appear to be accurate to a factor of about three, and the black-hole mass/bulge velocity dispersion relationship appears to be the same in active and quiescent galaxies.
