Critical and extremal gravitational collapse of a spherical charged scalar field in 4+1 spacetime dimensions

Satwik Mittal, Carsten Gundlach, Laetitia Martel

We numerically investigate the gravitational collapse of a charged scalar field coupled to the Einstein and Maxwell equations in spherical symmetry, in 4+1 spacetime dimensions. At…

Simulations of gravitational collapse in null coordinates IV: evolving through the event horizon, with an application to the spherical charged scalar field

Carsten Gundlach, Laetitia Martel

We consider line elements of the form $- 2 G d u (d x + B d u) + R^{2} (...)$ , where $(...)$ does not contain $d x$ . Surfaces of constant $u$ are then null surfaces, and their affinely par…
