Simulating binary black hole mergers using discontinuous Galerkin methods

Understand

Binary black holes are the most abundant source of gravitational-wave observations.

• Gravitational-wave observatories in the next decade will require tremendous increases in the accuracy of numerical waveforms modeling binary black holes, compared to today's state of the art.
• One approach to achieving the required accuracy is using spectral-type methods that scale to many processors.
• Using the SpECTRE numerical-relativity code, we present the first simulations of a binary black hole inspiral, merger, and ringdown using discontinuous Galerkin methods.
