Gravitational Waves and Computational General Relativity
Title: Gravitational Waves and Computational General Relativity
Abstract: In September of 2015, the Laser Interferometer Gravitational-wave Observatory made the first ever direct detection of gravitational waves from colliding black holes. The significance of this discovery is profound. It confirms the last of the original predictions by which Einstein distinguished his general theory of relativity from Newtonian gravity. It marks the opening of an entirely new spectrum for astronomical observation. And it allows us to study, empirically, the violent, nonlinear dynamics of nothingness – that is, the structure of spacetime itself. In this talk, we will explore the techniques that make such difficult and profound measurements possible, including my own field of study: the computational simulation of spacetime dynamics, a tool by which we hope to infer the structure of gravitational-wave sources from measured waveforms.
The seminar will take place in Olin 114, beginning at 3:30pm. Refreshments will be served, as well.
