3D MHD Simulation of a Pulsationally-Driven MRI Decretion Disc
Sean M. Ressler
We explore the pulsationally driven orbital mass ejection mechanism for Be star disc formation using isothermal, 3D magnetohydrodynamic (MHD) and hydrodynamic simulations. Non-radi…
Iharm3D: Vectorized General Relativistic Magnetohydrodynamics
Cora Prather, George N. Wong, Vedant Dhruv +4
Iharm3D is an open-source C code for simulating black hole accretion systems in arbitrary stationary spacetimes using ideal general-relativistic magnetohydrodynamics (GRMHD). It is…
Relative depolarization of the black hole photon ring in GRMHD models of Sgr A* and M87*
A. Jiménez-Rosales, J. Dexter, S. M. Ressler +15
Using general relativistic magnetohydrodynamic simulations of accreting black holes, we show that a suitable subtraction of the linear polarization per pixel from total intensity i…
Magnetically Modified Spherical Accretion in GRMHD: Reconnection-Driven Convection and Jet Propagation
Sean M. Ressler, Eliot Quataert, Christopher J. White +1
We present 3D general relativistic magnetohydrodynamic(GRMHD) simulations of zero angular momentum accretion around a rapidly rotating black hole, modified by the presence of initi…
