Studying the equations of General Relativity and beyond, both analytically and with state-of-the-art simulations.
Novel numerical and mathematical approaches can shed light on the structure and stability of spacetimes in general relativity and gravitational theories beyond it. This understanding can help us to answer questions about why the Universe has the features it does, and how generic these are in similar types of gravitational theories, spacetimes with different asymptotic behaviours or higher dimensional spacetimes.
For instance, mathematical studies of the well posedness of gravitational theories and associated numerical techniques have recently been applied in testing fundamental physics using gravitational waveforms from binary black holes. Researchers from the GWI have contributed significantly to these advances, building on their role as key developers of the numerical relativity code GRChombo.
