Black hole mass and Eddington ratio distributions of less-luminous quasars at $z\sim 4$ in the Subaru Hyper Suprime-Cam Wide field

Wanqiu He, Masayuki Akiyama, Motohiro Enoki +11

We investigate the black hole mass function (BHMF) and Eddington ratio distribution function (ERDF) of broad-line AGNs at z=4, based on a sample of 52 quasars with i<23.2 at 3.50 <…
