 Title: Development and Application of Numerical Techniques for General-Relativistic Magnetohydrodynamics Simulations of Black Hole Accretion Authors: White, Christopher Advisors: Stone, James M. Contributors: Astrophysical Sciences Department Keywords: accretionblack holegeneral relativitymagnetohydrodynamicssimulation Subjects: Astrophysics Issue Date: 2016 Publisher: Princeton, NJ : Princeton University Abstract: We describe the implementation of sophisticated numerical techniques for general-relativistic magnetohydrodynamics simulations in the Athena++ code framework. Improvements over many existing codes include the use of advanced Riemann solvers and of staggered-mesh constrained transport. Combined with considerations for computational performance and parallel scalability, these allow us to investigate black hole accretion flows with unprecedented accuracy. The capability of the code is demonstrated by exploring magnetically arrested disks.
