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…
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 char…
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…
Evolution of creases on the event horizon of a black hole merger
Maxime Gadioux, Robie A. Hennigar, Harvey S. Reall
A generic black hole merger occurs through a restructuring of creases (sharp edges) on the event horizon. This process is studied for a black hole merger in the limit of infinite m…
Creases, corners and caustics: properties of non-smooth structures on black hole horizons
Maxime Gadioux, Harvey S. Reall
The event horizon of a dynamical black hole is generically a non-smooth hypersurface. We classify the types of non-smooth structure that can arise on a horizon that is smooth at la…
