Numerical evolutions with the Kadath library: Application to the Schwarzschild black hole and Teukolsky gravitational waves
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.
Beyond Einstein: An assessment of higher curvature gravity,
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.
