GRChombo: An adaptable numerical relativity code for fundamental physics
Tomas Andrade, Llibert Areste Salo, Josu C. Aurrekoetxea +29
GRChombo is an open-source code for performing Numerical Relativity time evolutions, built on top of the publicly available Chombo software for the solution of PDEs. Whilst GRChomb…
A symmetric hyperbolic formulation of the vacuum Einstein equations in affine-null coordinates
Justin L. Ripley
We present a symmetric hyperbolic formulation of the Einstein equations in affine-null coordinates. Giannakopoulos et. al. (arXiv:2007.06419) recently showed that the most commonly…
Dynamics of spontaneous black hole scalarization and mergers in Einstein-scalar-Gauss-Bonnet gravity
William E. East, Justin L. Ripley
We study the dynamics of black holes in Einstein-scalar-Gauss-Bonnet theories that exhibit spontaneous black hole scalarization using recently introduced methods for solving the fu…
Evolution of Einstein-scalar-Gauss-Bonnet gravity using a modified harmonic formulation
William E. East, Justin L. Ripley
We present numerical solutions of several spacetimes of physical interest, including binary black hole mergers, in shift-symmetric Einstein-scalar-Gauss-Bonnet (ESGB) gravity, and…
Dynamics of a Z2 symmetric EdGB gravity in spherical symmetry
Justin L. Ripley, Frans Pretorius
We report on a numerical investigation of black hole evolution in an Einstein dilaton Gauss-Bonnet (EdGB) gravity theory where the Gauss-Bonnet coupling and scalar (dilaton) field…
Scalarized Black Hole dynamics in Einstein dilaton Gauss-Bonnet Gravity
Justin L. Ripley, Frans Pretorius
We report on a numerical investigation of the stability of scalarized black holes in Einstein dilaton Gauss-Bonnet (EdGB) gravity in the full dynamical theory, though restricted to…
