Simulations of black holes in compactified spacetimes
Zilhão, Miguel; Cardoso, Vitor; Gualtieri, Leonardo; Herdeiro, Carlos; Nerozzi, Andrea; Sperhake, Ulrich; Witek, HelviFrom the gauge/gravity duality to braneworld scenarios, black holes in compactified spacetimes play an important role in fundamental physics. Our current understanding of black hole solutions and their dynamics in such spacetimes is rather poor because analytical tools are capable of handling a limited class of idealized scenarios, only. Breakthroughs in numerical relativity in recent years, however, have opene...
Black holes in a box: Toward the numerical evolution of black holes in AdS spac...
Witek, Helvi; Cardoso, Vitor; Herdeiro, Carlos; Nerozzi, Andrea; Sperhake, Ulrich; Zilhão, MiguelThe evolution of black holes in "confining boxes" is interesting for a number of reasons, particularly because it mimics the global structure of anti-de Sitter geometries. These are nonglobally hyperbolic space-times and the Cauchy problem may only be well defined if the initial data are supplemented by boundary conditions at the timelike conformal boundary. Here, we explore the active role that boundary condit...
Numerical relativity for D dimensional space-times: Head-on collisions of black...
Witek, Helvi; Zilhão, Miguel; Gualtieri, Leonardo; Cardoso, Vitor; Herdeiro, Carlos; Nerozzi, Andrea; Sperhake, UlrichHigher dimensional black holes play an exciting role in fundamental physics, such as high energy physics. In this paper, we use the formalism and numerical code reported in [1] to study the head-on collision of two black holes. For this purpose we provide a detailed treatment of gravitational wave extraction in generic D dimensional space-times, which uses the Kodama-Ishibashi formalism. For the first time, we ...
