Panel A: eddington ratio distributions of red quasars and unobscured type 1 quasars at z ~ 0.7. The red solid and blue dashed histograms represent red quasars and unobscured type 1 quasars, respectively. The Eddington ratios of red quasars at z ~ 0.7 are adopted from Kim et al. (2015b). Panel B: eddington ratio distributions for high-luminous quasars (46.6 <log(L_bol∕erg s⁻¹) < 47.2). Panel C: eddington ratio distributions for low-luminous quasars (46.0 < log(L_bol∕erg s⁻¹) < 46.6).
