Black Hole Masses and Eddington Ratios at 0.3 &lt;<i>z</i>&lt; 4

Abstract

We study the distribution of Eddington luminosity ratios, L boj/L Edd, of active galactic nuclei (AGNs) discovered in the AGN and Galaxy Evolution Survey (AGES). We combine Hβ, Mg II, and C IV line widths with continuum luminosities to estimate black hol
