Spin measurement of 4U 1543-47 with Insight-HXMT and NICER from its 2021 outburst: A test of accretion disk models at high luminosities
E. S. Yorgancioglu, Q. C. Bu, A. Santangelo +7
4U 1543--47 is one of a handful of known black hole candidates located in the Milky Way Galaxy, and has undergone a very bright outburst in 2021, reaching a total of 9 Crab,…
Spectral calculations of 3D RMHD simulations of super-Eddington accretion onto a stellar-mass black hole
Brianna S. Mills, Shane W. Davis, Yan-Fei Jiang +1
We use the Athena++ Monte Carlo (MC) radiation transfer module to post-process simulation snapshots from non-relativistic Athena++ radiation magnetohydrodynamic (RMHD) simulations.…
An Extension of the Athena++ Code Framework for Radiation-Magnetohydrodynamics in General Relativity Using a Finite-Solid-Angle Discretization
Christopher J. White, Patrick D. Mullen, Yan-Fei Jiang +4
We extend the general-relativistic magnetohydrodynamics (GRMHD) capabilities of Athena++ to incorporate radiation. The intensity field in each finite-volume cell is discretized in…
A Bright First Day for Tidal Disruption Event
Xiaoshan Huang, Shane W. Davis, Yan-fei Jiang
Stream-stream collision may be an important pre-peak energy dissipation mechanism in tidal disruption events (TDEs). We perform local three-dimensional radiation hydrodynamic simul…
Global Three-Dimensional Radiation Magnetohydrodynamic Simulations of Accretion onto a Stellar Mass Black Hole at Sub- and Near-critical Accretion Rates
Jiahui Huang, Yan-Fei Jiang, Hua Feng +3
We present global 3D radiation magnetohydrodynamical simulations of accretion onto a 6.62 solar mass black hole with quasi-steady state accretion rates reaching 0.016 to 0.9 times…
Magnetohydrodynamic Simulations of Active Galactic Nucleus Disks and Jets
Shane W. Davis, Alexander Tchekhovskoy
There is a broad consensus that accretion onto supermassive black holes and consequent jet formation power the observed emission from active galactic nuclei (AGNs). However, there…
