Systematically smaller single-epoch quasar black hole masses using a radius-luminosity relationship corrected for spectral bias
Jaya Maithil, Michael S. Brotherton, Ohad Shemmer +6
Determining black hole masses and accretion rates with better accuracy and precision is crucial for understanding quasars as a population. These are fundamental physical properties…

Can X-ray Observations Improve Optical-UV-based Accretion-Rate Estimates for Quasars?
Andrea Marlar, Ohad Shemmer, Michael S. Brotherton +2
Current estimates of the normalized accretion rates of quasars (L/L_Edd), rely on measuring the velocity widths of broad optical-UV emission lines (e.g., H and Mg II $\lambda280…
