Radiation hydrodynamics models of active galactic nuclei: beyond the central parsec

Radiation hydrodynamics models of active galactic nuclei: beyond the central parsec
Radiation hydrodynamics models of active galactic nuclei: beyond the central parsec
We produce radiation hydrodynamics models of an active galactic nucleus torus plus outflow on 1–100 pc scales. This large scale permits direct comparison with observations, provides justification for configurations used in radiation transfer models, and tests the sensitivity of results of smaller scale dynamical models. We find that anisotropic radiation from an active galactic nucleus accretion disk can cause an outflow to evolve to become more polar, agreeing with the ubiquity of polar extended mid-infrared emission, and the general geometry predicted by radiative transfer models. We also find that the velocity maps can reproduce many features of observations, including apparent counterrotation.

Abstract

We produce radiation hydrodynamics models of an active galactic nucleus torus plus outflow on 1–100 pc scales. This large scale permits direct comparison with observations, provides justification for configurations used in radiation transfer models, and tests the sensitivity of results of smaller scale dynamical models. We find that anisotropic radiation from an active galactic nucleus accretion disk can cause an outflow to evolve to become more polar, agreeing with the ubiquity of polar extended mid-infrared emission, and the general geometry predicted by radiative transfer models. We also find that the velocity maps can reproduce many features of observations, including apparent counterrotation.
