Research Abstract

We have theoretically investigated structures and dynamics of the ISM around supermassive black holes in galaxies. Using three-dimensional radiation-hydrodynamics simulations, we confirmed that non-steady and non-uniform outflows are generated due to the radiation pressure and heating. This outflow does not prevent from accreting materials toward the galactic center. We also found that a part of failed outflows naturally form an obscuring torus, which has been postulated to explain observed properties of AGNs. The radiation-driven outflows are ubiquitous over a large dynamic range, for example, we found that strong line-driven winds are formed from the accretion disk, and this consistently explains broad-absorption line quasars.
