Title: AR: Calibrating the Black-Hole Mass Scaling Relations using Reverberation-Mapped Active Galaxies with Velocity-Resolved Measurements
Cycle: 30

Abstract
Reverberation mapping (RM) determines the mass of black holes (MBH) in active galactic nuclei (AGNs) by resolving the BH gravitational sphere of influence "in time". The resulting relationship between broad-line region (BLR) radius and AGN luminosity (the "R-L relation") is the foundation of virtually all MBH measurements beyond the local universe. Recent RM campaigns with high-quality data (cadence and S/N) yielded velocity-resolved time lags and independent BH masses for a sample of 29 objects, spanning a wide range of AGN luminosities and BH masses (6.4
