Radiation pressure-driven outflows from dusty AGN

ABSTRACT Radiation pressure-driven outflows from luminous accreting supermassive black holes are an important part of active galactic nucleus (AGN) feedback. The effective Eddington limit, based on absorption radiation by dust, not electron scattering, is revealed in the plane AGN column density NH as a function fraction ?Edd = Lbol/LEdd, where lack objects seen region limit exceeded. Here, we conduct simulation using cloudy code to deduce radiative force applied dusty gas at and compare gravitational reveal outflow its boundary with long-lived clouds. We also investigate how condition affected various dust properties distribution. As expected, abundance has largest effect NH–?Edd diagram since higher abundance, more feedback, while impact inner radius shell, shell width, spectral shape relatively negligible. presence other central masses, such nuclear star cluster, can make feedback less effective. energy distribution depends mass hole spin. Though effects small, ionizing ultraviolet photons blackbody accretion disc than spin, influence efficiency pressure.
