Formation of extremal Reissner-Nordström black holes: insights from numerics
Maxime Gadioux, Harvey S. Reall, Jorge E. Santos
An extremal Reissner-Nordström black hole can form in finite time in the gravitational collapse of a massless charged scalar field. The proof of this is based on the method of cha…

Violation of the third law of black hole mechanics in vacuum gravity
John R. V. Crump, Maxime Gadioux, Harvey S. Reall +1
We demonstrate numerically the existence of solutions of five-dimensional vacuum gravity describing the formation, in finite time, of an extremal rotating black hole from a pre-exi…

The merger of a black hole with a cosmological horizon
Maxime Gadioux, Hangzhi Wang
In recent years there have been many studies on exactly solvable black hole mergers, based on a model by Emparan and Martinez where the mass of one black hole is blown up to infini…
