Abstract

The masses of the central black holes have been measured for nearly 50 AGNs by using emissionline reverberation mapping. We briefly outline the process by which this is done and discuss the evidence about how reliable the derived masses might be. We outline how reverberation mapping underpins the mass estimates for all AGNs, including high-redshift quasars, and point out that the mass estimates are based on reasonable, yet unproven, assumptions. Finally, we briefly discuss results on reverberation velocity-delay maps that are revealing the kinematics of the broad-line region and yielding direct measurements of black hole masses.
