MSc Defense: Jorge Expósito Patiño

On Friday June 9 2023 at 10.00 in auditorium B at Blegdamsvej, Jorge Expósito Patiño will defend his master thesis supervised by Thomas Baumgarte (Bowdoin College), Vitor Cardoso and Troels Haugbølle. Censor will be Steen Hannestad (AU). The thesis defense will be in English.

Title: Numerical Relativity in Axisymmetry

Abstract: Numerical relativity, the branch of general relativity that uses simulations to solve the Einstein equations, has proven an invaluable tool in studying gravity, from gravitational wave astronomy to foundational questions such as cosmic censorship and space-time stability studies. Most current numerical relativity codes use Cartesian or spherical coordinates, which are not ideally suited to many systems that present structure around an axis, examples of which are black hole head-on collisions and critical collapse around an axis. In this thesis, I present the new code I have created to do numerical relativity simulations with a free choice of spatial coordinates, and present results and simulations in both cylindrical and spherical coordinates.
