The role of infrared radiation pressure in shaping dusty winds in AGN
Marta Venanzi, Sebastian Hönig, David Williamson
The detection of dusty winds dominating the infrared emission of AGN on parsec scales has revealed the limitations of traditional radiative transfer models based on a toroidal dist…
Radiation hydrodynamics models of Active Galactic Nuclei: Beyond the central parsec
David Williamson, Sebastian Hönig, Marta Venanzi
We produce radiation hydrodynamics models of an AGN 'torus' plus outflow on 1-100 pc scales. This large scale permits direct comparison with observations, provides justification fo…
Parsec-scale Dusty Winds in Active Galactic Nuclei: Evidence for Radiation Pressure Driving
James H. Leftley, Sebastian F. Hönig, Daniel Asmus +5
Infrared interferometry of local AGN has revealed a warm (~300K-400K) polar dust structure that cannot be trivially explained by the putative dust torus of the unified model. This…
3D Radiation hydrodynamics of a dynamical torus
David Williamson, Marta Venanzi, Sebastian Hönig
We have developed a new dynamical model of the torus region in active galactic nucleus (AGN), using a three-dimensional radiation hydrodynamics algorithm. These new simulations hav…
Bianchi I cosmology in the presence of a causally regularized viscous fluid
Giovanni Montani, Marta Venanzi
We analyze the dynamics of a Bianchi I cosmology in the presence of a viscous fluid, causally regularized according to the Lichnerowicz approach. We show how the effect induced by…
