Quasi-Normal Modes of a Schwarzschild White Hole
Nigel T. Bishop, Amos S. Kubeka
We investigate perturbations of the Schwarzschild geometry using a linearization of the Einstein vacuum equations within a Bondi-Sachs, or null cone, formalism. We develop a numeri…
Strategies for the Characteristic Extraction of Gravitational Waveforms
M. C. Babiuc, N. T. Bishop, B. Szilagyi +1
We develop, test and compare new numerical and geometrical methods for improving the accuracy of extracting waveforms using characteristic evolution. The new numerical method invol…
Numerical relativity with characteristic evolution, using six angular patches
Christian Reisswig, Nigel T. Bishop, Chi Wai Lai +2
The characteristic approach to numerical relativity is a useful tool in evolving gravitational systems. In the past this has been implemented using two patches of stereographic ang…
