Magnetohydrodynamic Simulations of Galaxies for Next Generation Supercomputers

Usage Details

While magnetic fields are present in all galaxies, the full nature of their coupling is still debated. The coevolution of galaxies and their magnetic fields can be studied through Magnetohydrodynamic (MHD) models. Higher order and higher resolution MHD methods are needed to provide more physically realistic simulations, but these require efficient usage of large scale computational resources. To explore next generation MHD simulations of galaxies, I will use K-Athena, a CPU and GPU performant version of the MHD code Athena++, to simulate magnetic turbulence in the Taylor-Green vortex. I will use work with K-Athena to inform high resolution galaxy simulations using Enzo-E, a cosmology code built for exascale, with higher order MHD methods.
