Binary AGN simulations with radiation pressure reveal a new duty cycle, and a reduction of gravitational torque, through 'minitori' structures
David J. Williamson, Lars H. Bösch, Sebastian F. Hönig
We produce the first set of radiation hydrodynamics simulations of binary AGNs at parsec-scale separation in scale-model simulations. We use SPH for hydrodynamics, and raytracing t…
The Galaxy Activity, Torus and Outflow Survey (GATOS): II. Torus and polar dust emission in nearby Seyfert galaxies
A. Alonso-Herrero, S. García-Burillo, S. F. Hoenig +30
We compare mid-IR and ALMA far-IR images of 12 nearby Seyferts selected from GATOS. The mid-IR unresolved emission contributes more than 60% of the nuclear emission in most galaxie…
The Evolution of Magellanic-like Galaxy Pairs and The Production of Magellanic Stream Analogues in Simulations with Tides, Ram Pressure, and Stellar Feedback
David Williamson, Hugo Martel
We present a series of chemodynamical simulations of Magellanic-like systems consisting of two interacting, equal-mass dwarf galaxies orbiting a massive host galaxy, including feed…
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…
