On characteristic initial data for a star orbiting a black hole
Nigel T. Bishop, Roberto Gomez, Luis Lehner +2
We take further steps in the development of the characteristic approach to enable handling the physical problem of a compact self-gravitating object, such as a neutron star, in clo…
The incorporation of matter into characteristic numerical relativity
N. T. Bishop, R. Gomez, L. Lehner +2
A code that implements Einstein equations in the characteristic formulation in 3D has been developed and thoroughly tested for the vacuum case. Here, we describe how to incorporate…
Black Hole Data via a Kerr-Schild Approach
Nigel T. Bishop, Richard Isaacson, Manoj Maharaj +1
We present a new approach for setting initial Cauchy data for multiple black hole spacetimes. The method is based upon adopting an initially Kerr-Schild form of the metric. In the…
High-powered Gravitational News
Nigel T. Bishop, Roberto Gómez, Luis Lehner +2
We describe the computation of the Bondi news for gravitational radiation. We have implemented a computer code for this problem. We discuss the theory behind it as well as the resu…
