FUGUE: A New GPU-accelerated General Relativistic Magnetohydrodynamics Code with Weak-Field Multipole Self-Gravity and Quasi-Stationary Kerr Black Hole Evolution

We present FUGUE, a new GPU-accelerated code for general relativistic magnetohydrodynamics (GRMHD). The code supports an optional quasi-stationary update of the Kerr black hole mass and spin, as well as weak-field multipole self-gravity computed with a spherical harmonic Poisson solver. The calculat
