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…
Transient jet formation and state transitions from large-scale magnetic reconnection in black hole accretion discs
Jason Dexter, Jonathan C. McKinney, Sera Markoff +1
Magnetically arrested accretion discs (MADs), where the magnetic pressure in the inner disc is dynamically important, provide an alternative mechanism for regulating accretion to w…
Numerical simulations of super-critical black hole accretion flows in general relativity
A. Sadowski, R. Narayan, J. C. McKinney +1
A new general relativistic radiation magnetohydrodynamical code KORAL, is described, which employs the M1 scheme to close the radiation moment equations. The code has been successf…
Submillimeter Quasi-Periodic Oscillations in Magnetically Choked Accretion Flows Models of Sgr A*
Roman V. Shcherbakov, Jonathan C. McKinney
High-frequency quasi-periodic oscillations (QPOs) appear in general-relativistic magnetohydrodynamic simulations of magnetically choked accretion flows around rapidly rotating blac…
