Excised black hole spacetimes: quasi-local horizon formalism applied to the Kerr example
Nicolas Vasset, Jérôme Novak, José Luis Jaramillo
We present a numerical work aiming at the computation of excised initial data for black hole spacetimes in full general relativity, using Dirac gauge in the context of a constraine…
Isolated Horizon structures in quasiequilibrium black hole initial data
José Luis Jaramillo
Isolated horizon conditions enforce the time invariance of both the intrinsic and the extrinsic geometry of a (quasilocal) black hole horizon. Nonexpanding horizons, only requiring…
Improved constrained scheme for the Einstein equations: An approach to the uniqueness issue
Isabel Cordero-Carrión, Pablo Cerdá-Durán, Harald Dimmelmeier +3
Uniqueness problems in the elliptic sector of constrained formulations of Einstein equations have a dramatic effect on the physical validity of some numerical solutions, for instan…
New theoretical approaches to black holes
Eric Gourgoulhon, Jose Luis Jaramillo
Quite recently, some new mathematical approaches to black holes have appeared in the literature. They do not rely on the classical concept of event horizon -- which is very global,…
Numerical implementation of isolated horizon boundary conditions
J. L. Jaramillo, M. Ansorg, F. Limousin
We study the numerical implementation of a set of boundary conditions derived from the isolated horizon formalism, and which characterize a black hole whose horizon is in quasi-equ…
