Strong Gravity News & Events

Numerical Relativity is a key tool for the study of strong-field gravity. I will present a new evolution code, based on the Kadath library. It relies on multidomain spectral methods for the space discretization, and explicit time integration schemes.

The Einstein-Hilbert action is the simplest possible generally covariant action for gravity. While Einstein's equations conform with all observational data, theoretical considerations suggest the possibility to add higher curvature correction terms to Einstein's theory.

The prospect of a stochastic gravitational wave (GW) background from the primordial universe offers a promising new window for cosmology and fundamental physics.
