Astrophysics Lectures - Simulating Black Holes - Maria Okounkova - 08/17/2018

Find out how astrophysicists harness supercomputers to simulate many physical scenarios including the merger of two black holes. Lecture: 03:53; Lecture Q&A: 35:30; Panel Q&A: 35:30 Date: August 17, 2018 Lecturer: Maria Okounkova Title: Simulating Black Holes Abstract: Computational physics takes us where pencil and paper calculations often cannot -- to the most dynamical, complicated astrophysical scenarios. This includes the merger of black hole binaries, where the final stages of two black holes joining together to become one highly distorts spacetime. Being able to model such a system is important for gravitational wave detection from such binary black hole mergers, but is only possible via simulation -- using powerful computers to perform calculations to see what such a system looks like. I will talk about computational physics: what it is, what its capabilities are, and how it's used in studying black holes today. We will go through some simple examples to see what performing a physical simulation actually means. I will also describe the differences and similarities between computational physics simulations and the sort of simulations performed in CGI animation.
