Simulating Binary Black Holes with SpECTRE

In the next decade, a new generation of observatories on Earth and in space will observe gravitational waves from binary black holes with unprecedented sensitivity. Interpreting these observations will require models of the gravitational waveforms much more accurate than today's state of the art. Because these models require numerical relativity near the time of merger, numerical-relativity simulations of binary black holes will also need to be significantly more accurate. SpECTRE is a next-generation, open-source numerical-relativity code that aims to achieve the accuracy future observatories will need by combining a discontinuous Galerkin method with task-based parallelism. In this talk, I will discuss SpECTRE's first complete simulations of binary black holes through inspiral, merger, and ringdown, including the accuracy of the simulated gravitational waveforms.
