Variability in Black Hole Accretion: Dependence on Rotational and Magnetic Energy Balance
Hyerin Cho, Ramesh Narayan
Most general relativistic magnetohydrodynamic simulations of black hole (BH) hot accretion flows are initialized with small rotating tori and produce stable jets with only small fl…
Radiative, two-temperature simulations of low luminosity black hole accretion flows in general relativity
A. Sadowski, M. Wielgus, R. Narayan +3
We present a numerical method which evolves a two-temperature, magnetized, radiative, accretion flow around a black hole, within the framework of general relativistic radiation mag…
Three-Dimensional General Relativistic Radiation Magnetohydrodynamical Simulation of Super-Eddington Accretion, using a new code HARMRAD with M1 Closure
Jonathan C. McKinney, Alexander Tchekhovskoy, Aleksander Sadowski +1
Black hole (BH) accretion flows and jets are dynamic hot relativistic magnetized plasma flows whose radiative opacity can significantly affect flow structure and behavior. We descr…
Energy, momentum and mass outflows and feedback from thick accretion discs around rotating black holes
A. Sadowski, R. Narayan, R. Penna +1
Using long-duration general relativistic magnetohydrodynamic simulations of radiatively inefficient accretion discs, the energy, momentum and mass outflow rates from such systems a…
Simulations of Ultrarelativistic Magnetodynamic Jets from Gamma-ray Burst Engines
Alexander Tchekhovskoy, Jonathan C. McKinney, Ramesh Narayan
Long-duration gamma-ray bursts (GRBs) require an engine capable of driving a jet of plasma to ultrarelativistic bulk Lorentz factors of up to several hundred and into narrow openin…
Three-dimensional MHD Simulations of Radiatively Inefficient Accretion Flows
Igor V. Igumenshchev, Ramesh Narayan, Marek A. Abramowicz
We present three-dimensional MHD simulations of rotating radiatively inefficient accretion flows onto black holes. In the simulations, we continuously inject magnetized matter into…
