Using SpECTRE to simulate binary-black-hole inspirals

Future gravitational-wave observatories, such as the Einstein Telescope, Cosmic Explorer, and LISA will measure gravitational waves with signal-to-noise ratios in the thousands. Interpreting these observations without bias will require gravitational waves with much higher accuracy. SpECTRE is a next-generation numerical-relativity code that aims to achieve this accuracy by combining Discontinuous Galerkin methods with task-based parallelism to enable scaling to many more processors than its predecessor, SpEC. In this talk, I will discuss the current status of binary-black-hole simulations with SpECTRE, including comparisons with analogous simulations using SpEC.
