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…
Star Formation History in Barred Spiral Galaxies. AGN Feedback
Fidèle Robichaud, David Williamson, Hugo Martel +2
We present a numerical study of the impact of AGN accretion and feedback on the star formation history of barred disc galaxies. Our goal is to determine whether the effect of feedb…
Metal diffusion in smoothed particle hydrodynamics simulations of dwarf galaxies
David John Williamson, Hugo Martel, Daisuke Kawata
We perform a series of smoothed particle hydrodynamics simulations of isolated dwarf galaxies to compare different metal mixing models. In particular, we examine the role of diffus…
