The Sloan Digital Sky Survey Reverberation Mapping Project Radius Luminosity Relation

Results from a few decades of reverberation mapping (RM) studies have revealed a correlation between the radius of the broad-line emitting region and the continuum luminosity of active galactic nuclei. This "radius-luminosity" relation allows us to estimate black-hole masses across cosmic time, using single-epoch spectroscopy rather than long-term RM monitoring. I will discuss results from the Sloan Digital Sky Survey Reverberation Mapping project that differ significantly from the previously established radius-luminosity relation, introducing new challenges for single-epoch black hole masses.
