Electromagnetic Observables of Weakly Collisional Black Hole Accretion
Vedant Dhruv, Ben Prather, Mani Chandra +2
The black holes in the Event Horizon Telescope sources Messier 87* and Sagittarius A* (SgrA*) are embedded in a hot, collisionless plasma that is fully described in kinetic theory…
How important is non-ideal physics in simulations of sub-Eddington accretion onto spinning black holes?
Francois Foucart, Mani Chandra, Charles F. Gammie +2
Black holes with accretion rates well below the Eddington rate are expected to be surrounded by low-density, hot, geometrically thick accretion disks. This includes the two black h…
Polarized Synchrotron Emissivities and Absorptivities for Relativistic Thermal, Power-Law, and Kappa Distribution Functions
Alex Pandya, Zhaowei Zhang, Mani Chandra +1
Synchrotron emission and absorption determine the observational appearance of many astronomical systems. In this paper, we describe a numerical scheme for calculating synchrotron e…
Evolution of Accretion Discs around a Kerr Black Hole using Extended Magnetohydrodynamics
Francois Foucart, Mani Chandra, Charles F. Gammie +1
Black holes accreting well below the Eddington rate are believed to have geometrically thick, optically thin, rotationally supported accretion discs in which the Coulomb mean free…
Electron Thermodynamics in GRMHD Simulations of Low-Luminosity Black Hole Accretion
Sean M. Ressler, Alexander Tchekhovskoy, Eliot Quataert +2
Simple assumptions made regarding electron thermodynamics often limit the extent to which general relativistic magnetohydrodynamic (GRMHD) simulations can be applied to observation…
An Extended Magnetohydrodynamics Model for Relativistic Weakly Collisional Plasmas
Mani Chandra, Charles F. Gammie, Francois Foucart +1
Black holes that accrete far below the Eddington limit are believed to accrete through a geometrically thick, optically thin, rotationally supported plasma that we will refer to as…
