BH Punctures as Initial Data for General Relativity
S. R. Brandt, B. Bruegmann
Abstract
We construct initial data for several black holes with arbitrary momenta and spins by a new method that is based on a compactification of Brill-Lindquist wormholes. When treated numerically, the method leads to a significant simplification over the conventional approach which is based on throats and an isometry condition.
