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…

Magnetohydrodynamic Simulations of Transonic Accretion Flows
Raj Kishor Joshi, Antonios Tsokaros, Sanjit Debnath +2
Theoretical studies of transonic accretion onto black holes reveal a wide range of possible solutions, broadly classified into smooth flows and flows featuring shocks. Accretion so…

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…
