Gravitational Wave Heating

Vishnu Kakkat, Nigel T. Bishop, Amos S. Kubeka

It was shown in previous work that when a gravitational wave (GW) passes through a viscous shell of matter the magnitude of the GW will be damped and there are astrohysical circums…

Numerical convergence of model Cauchy-characteristic extraction and matching

Thanasis Giannakopoulos, Nigel T. Bishop, David Hilditch +2

Gravitational waves provide a powerful enhancement to our understanding of fundamental physics. To make the most of their detection we need to accurately model the entire process o…

Effect of a viscous fluid shell on the propagation of gravitational waves

Nigel T. Bishop, Petrus J. van der Walt, Monos Naidoo

In this paper we show that there are circumstances in which the damping of gravitational waves (GWs) propagating through a viscous fluid can be highly significant; in particular, t…

Gauge structure of the Einstein field equations in Bondi-like coordinates

Thanasis Giannakopoulos, Nigel T. Bishop, David Hilditch +2

The characteristic initial (boundary) value problem has numerous applications in general relativity (GR) involving numerical studies, and is often formulated using Bondi-like coord…

Modifications to the signal from a gravitational wave event due to a surrounding shell of matter

Monos Naidoo, Nigel T Bishop, Petrus J van der Walt

In previous work, we established theoretical results concerning the effect of matter shells surrounding a gravitational wave (GW) source, and we now apply these results to astrophy…
