Damping of MHD Turbulence in A Partially Ionized Medium
Yue Hu, Siyao Xu, Lev Arzamasskiy +2
The coupling state between ions and neutrals in the interstellar medium plays a key role in the dynamics of magnetohydrodynamic (MHD) turbulence, but is challenging to study numeri…
Implementation of chemistry in the Athena++ code
Munan Gong, Ka-Wai Ho, James M. Stone +6
Chemistry plays a key role in many aspects of astrophysical fluids. Atoms and molecules are agents for heating and cooling, determine the ionization fraction, serve as observationa…
Mahakala: a Python-based Modular Ray-tracing and Radiative Transfer Algorithm for Curved Space-times
Aniket Sharma, Lia Medeiros, Chi-kwan Chan +4
We introduce Mahakala, a Python-based, modular, radiative ray-tracing code for curved space-times. We employ Google's JAX framework for accelerated automatic differentiation, which…
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…
The Athena++ Adaptive Mesh Refinement Framework: Multigrid Solvers for Self-Gravity
Kengo Tomida, James M. Stone
We describe the implementation of multigrid solvers in the Athena++ adaptive mesh refinement (AMR) framework and their application to the solution of the Poisson equation for self-…
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…
