The Dust-to-gas Ratio and the Role of Radiation Pressure in Luminous, Obscured Quasars
Abstract The absence of high-Eddington-ratio, obscured active galactic nuclei (AGNs) in local ( z ≲ 0.1) samples of moderate-luminosity AGNs has generally been explained to result from radiation pressure on the dusty gas governing the level of nuclear (≲10 pc) obscuration. However, very high accretion rates are routinely reported among …
