Flux-Averaged Force Multipliers
Sergei Dyda, Randall C. Dannen, Shane W. Davis +2
We apply novel developments in photoionization modeling and multi-frequency radiation hydrodynamics to the study of line driven AGN disc winds. We use a flux-averaged force multipl…

Time-Dependent AGN Disc Winds II -- Effects of Photoionization
Sergei Dyda, Randall C. Dannen, Timothy R. Kallman +2
We use a combination of radiation hydrodynamics (rad-HD) and photoionization modeling to study line-driven disc winds for a range of black hole masses. We refined previous models b…

We study line driven stellar winds using multifrequency, time-dependent radiation hydrodynamics. We compute the radiation force due to lines, the so called force multiplier, using…
