Observational and theoretical arguments suggest that the momentum carried in mass outows from AGN can reach several times L=c, corresponding to outow rates of hundreds of solar masses per year. Radiation pressure on resonant absorption lines alone may not be sucient to provide this momentum deposition, and the transfer of reprocessed IR radiation in dusty nuclear gas has been postulated to provide the extra enhancement. The ecacy of this mechanism, however, will be sensitive to multidimensional… Expand
ACTIVE GALACTIC NUCLEUS OBSCURATION FROM WINDS: FROM DUSTY INFRARED-DRIVEN TO WARM AND X-RAY PHOTOIONIZED.
TLDR
Infrared radiation (IR) is incorporated in radiation-hydrodynamic simulations adopting the flux-limited diffusion approximation and it is found that in the range of X-ray luminosities L=0.05 - 0.6Ledd, the Compton-thick part of the flow has an opening angle of approximately 72° - 75° regardless of the luminosity.

Radiation driven outflow in active galactic nuclei: the feedback effects of scattered and reprocessed photons
We perform time-dependent, two-dimensional, hydrodynamical, numerical simulations to study the dynamics of a slowly rotating accretion flow from sub-pc to pc scales under the irradiation from theExpand
Radiation-driven outflows from and radiative support in dusty tori of active galactic nuclei

Revisiting the ‘forbidden’ region: AGN radiative feedback with radiation trapping
Active galactic nucleus (AGN) feedback, driven by radiation pressure on dust, is an important mechanism for efficiently coupling the accreting black hole to the surrounding environment. RecentExpand
Dynamics of dusty radiation-pressure-driven shells and clouds: fast outflows from galaxies, star clusters, massive stars, and AGN
It is typically assumed that radiation pressure driven winds are accelerated to an asymptotic velocity of V ~ v_esc, where v_esc is the escape velocity from the central source. We note that this isExpand
AGN feedback: galactic-scale outflows driven by radiation pressure on dust
Galaxy-scale outows, which are thought to provide the link connecting the central black hole to its host galaxy, are now starting to be observed. However, the physical origin of the mechanism drivingExpand
Constraining the dynamical importance of hot gas and radiation pressure in quasar outflows using emission line ratios
Quasar feedback models often predict an expanding hot gas bubble which drives a galaxy-scale outflow. In many circumstances this hot gas radiates inefficiently and is therefore difficult to observeExpand
Thick turbulent gas disks with magnetocentrifugal winds in active galactic nuclei
Infrared high-resolution imaging and interferometry show that the dust distribution is frequently elongated along the polar direction of an AGN. In addition, interferometric mm line observations haveExpand
