Radiation GRMHD Models of Accretion onto Stellar-Mass Black Holes: III. Near-Eddington Accretion
Lizhong Zhang, James M. Stone, Shane W. Davis +3
We present a comprehensive analysis of four near-Eddington black hole accretion models from GRMHD simulations with full radiation transport. This study investigates the dynamical e…
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…
Radiation Magnetohydrodynamic Simulation of sub-Eddington Circumbinary Disk around an Equal-mass Massive Black Hole Binary
Vishal Tiwari, Chi-Ho Chan, Tamara BogdanoviÄ +3
We present the first three-dimensional radiation magnetohydrodynamic (RMHD) simulation of a sub-Eddington circumbinary disk (CBD) around an equal-mass massive black hole binary (MB…
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…
