On Stability and Evolution of Solutions in General Relativity
… characteristic problem of general relativistic magnetohydrodynamics (GRMHD). We compute the eigenvalues and eigenvectors of GRMHD and establish degeneracy conditions. Finally, we consider the initial value problem for axisymmetric GRMHD. We formulate the general Einstein and MHD equations under …

Black Hole Astrophysics : Magnetohydrodynamics on the Kerr Geometry
… physics in the regime of General Relativistic Magnetohydrodynamics (GRMHD). The behavior of non-radiative accretion flows and outflows on the Kerr space-time is analyzed. Basic equations of conservative GRMHD and aspects of numerical schemes are presented. Relativistic codes and astrophysical …

Dissipative heating and nonthermal distributions in black hole accretion flaring events
… to model these flares using general relativistic magnetohydrodynamics (GRMHD) and radiative transfer calculations with a nonthermal kappa distribution function (which effectively adds a power-law tail to the thermal distribution) for electrons accelerated by resistive heating in reconnecting …

General-relativistic magnetohydrodynamics simulations of black hole accretion disks: dynamics and radiative properties
… simulations, specifically general relativistic magnetohydrodynamics (GRMHD), to construct a realistic dynamical and radiation model of accretion disks. Our simulations are for black holes in low luminous regimes that probably possesses a hot and thick accretion disk. Flows in this regime are …

General relativistic radiation magnetohydrodynamics, with applications to black hole accretion disks
… of numerical methods for general relativistic magnetohydrodynamics (GRMHD). However, even the local details of MRI-driven turbulence simulations are still not completely understood. Along the way, this work considers a central issue with modeling the MRI: whether the resulting stress is …
