Asymptotically null slices in numerical relativity: mathematical analysis and spherical wave equation tests
Gioel Calabrese, Carsten Gundlach, David Hilditch
We investigate the use of asymptotically null slices combined with stretching or compactification of the radial coordinate for the numerical simulation of asymptotically flat space…

Numerical stability for finite difference approximations of Einstein's equations
Gioel Calabrese, Ian Hinder, Sascha Husa
We extend the notion of numerical stability of finite difference approximations to include hyperbolic systems that are first order in time and second order in space, such as those…

Excising a boosted rotating black hole with overlapping grids
Gioel Calabrese, David Neilsen
We use the overlapping grids method to construct a fourth order accurate discretization of a first order reduction of the Klein-Gordon scalar field equation on a boosted spinning b…
