Three-dimensional Global Relativistic Radiation Magnetohydrodynamics of Magnetically Arrested Disk Accretion Flows in AGNs
Ramiz Aktar, Kuo-Chuan Pan, Toru Okuda
We perform three-dimensional radiation-relativistic magnetohydrodynamic (3D Rad-RMHD) simulations of accretion flows around spinning active galactic nuclei (AGNs). Our study focuse…

Global resistive MHD accretion flows around spinning AGNs: impact of resistivity on MAD state
Ramiz Aktar, Kuo-Chuan Pan, Toru Okuda
In this study, we investigate the effect of resistivity on the dynamics of global magnetohydrodynamic accretion flows (Res-MHD) around a spinning supermassive black hole. We perfor…

Numerical studies of (in)stabilities of shocks in perturbed advective flows around black holes
Junxing Zhou, Junxiang Huang, Xin Chang +2
Using two-dimensional hydrodynamic simulations, we investigate the stability of shocked accretion flows around black holes under non-axisymmetric perturbations. By systematically e…
