Black hole initial data from a non-conformal decomposition
Nigel T. Bishop, Florian Beyer, Michael Koppitz
We present an alternative approach to setting initial data in general relativity. We do not use a conformal decomposition, but instead express the 3-metric in terms of a given unit…
New approach to calculating the News
Nigel T. Bishop, Shrirang S. Deshingkar
We consider the problem of finding the gravitational radiation output, or news, within the context of a numerical simulation of a spacetime by means of the null-cone, or characteri…
A numerical relativistic model of a massive particle in orbit near a Schwarzschild black hole
Nigel T. Bishop, Roberto Gomez, Sascha Husa +2
We present a method for computing the evolution of a spacetime containing a massive particle and a black hole. The essential idea is that the gravitational field is evolved using f…
