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…
