Semi-implicit scheme for treating radiation under M1 closure in general relativistic conservative fluid dynamics codes
Aleksander Sadowski, Ramesh Narayan, Alexander Tchekhovskoy +1
A numerical scheme is described for including radiation in multi-dimensional general-relativistic conservative fluid dynamics codes. In this method, a covariant form of the M1 clos…
Alignment of Magnetized Accretion Disks and Relativistic Jets with Spinning Black Holes
Jonathan C. McKinney, Alexander Tchekhovskoy, Roger D. Blandford
Accreting black holes (BHs) produce intense radiation and powerful relativistic jets, which are affected by the BH's spin magnitude and direction. While thin disks might align with…
Three-Dimensional Simulations of Magnetized Thin Accretion Disks around Black Holes: Stress in the Plunging Region
Rebecca Shafee, Jonathan C. McKinney, Ramesh Narayan +3
We describe three-dimensional general relativistic magnetohydrodynamic simulations of a geometrically thin accretion disk around a non-spinning black hole. The disk has a thickness…
WHAM: A WENO-based general relativistic numerical scheme I: Hydrodynamics
Alexander Tchekhovskoy, Jonathan C. McKinney, Ramesh Narayan
Active galactic nuclei, x-ray binaries, pulsars, and gamma-ray bursts are all believed to be powered by compact objects surrounded by relativistic plasma flows driving phenomena su…
