Numerical Relativity Simulations Beyond General Relativity

Black holes are among the most exciting predictions of Einstein's theory of general relativity, composed of the fabric of spacetime itself. Observations of black holes offer unique access to extreme gravity, and they enable us to investigate long-standing puzzles in fundamental physics ranging from dark matter to the very nature of gravity itself.

In my presentation, I will give a brief overview of recent black hole observations, including gravitational wave detections, and discuss how we produce theoretical models of black hole mergers and gravitational waves using numerical relativity.

I will share with you recent advances in modelling compact binaries in modified theories of gravity with particular focus on numerical relativity beyond general relativity, and I will highlight new dynamical phenomena that are absent in general relativity.
