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.

C. Herdeiro was one of the plenary invited speakers of the International Conference on Gravitation and Cosmology (ICGC 24) and the International Conference on Relativistic Astrophysics and Cosmology (ICRAC 24) that took place in Lahore, Pakistan on 29-31 Jan and 1-2 Feb 2024. Wonderful hospitality and great interactions. Science brings people together.
The prospect of a stochastic gravitational wave (GW) background from the primordial universe offers a promising new window for cosmology and fundamental physics.
