Disks, jets, and other black hole-powered transients

Black holes are responsible for a wide variety of astrophysical phenomena. They devour stars, eject relativistic jets, affect star formation and galaxy evolution, and enrich the Universe with heavy elements. I will discuss how global general relativistic magnetized fluid dynamics numerical simulations allow us to use this activity to quantitatively probe strong-field gravity and constrain black hole physics in various astrophysical contexts. In particular, I will show how the use of graphics processing units (GPUs) has advanced such simulations and how it can turn your desktop into an equivalent of a thousand-core supercomputer.
