Fully global numerical evolutions of the linearised spin-2 equation
Merlyn Barrer, Jörg Frauendiener, Jörg Hennig +3
We study the linearised spin-2 field on conformally compactified Minkowski spacetime. Initial data are prescribed on past null infinity , and the system is evolved t…
Wellposedness of the initial boundary value problem for the conformal field equations
Chris Stevens, Juan A. Valiente Kroon
We provide a formulation of the initial boundary value problem for Friedrich's extended conformal Einstein field equations in which boundary data is prescribed on a timelike hypers…
Fully non-linear gravitational wave simulations from past to future null-infinity
Jörg Frauendiener, Chris Stevens, Sebenele Thwala
We present the first numerical simulations of asymptotically flat space-times whose computational domain includes past and future null-infinity. As an application, we explore the s…
A numerical framework for studying asymptotic quantities
Breanna Camden, Jörg Frauendiener, Joseph Galinski +3
In this contribution we present an overview of our work on the numerical simulation of the perturbation of a black hole space-time by incoming gravitational waves. The formulation…
Non-linear scattering of plane gravitational and electromagnetic waves
Breanna Camden, Chris Stevens, John Forbes
Fully non-linear, plane-symmetric exact solutions of the Einstein equations describing the scattering of gravitational and electromagnetic waves have existed for many years. For th…
The non-linear perturbation of a black hole by gravitational waves. III. Newman-Penrose constants
Jörg Frauendiener, Alex Goodenbour, Chris Stevens
In this paper we continue our study of the non-linear response of a Schwarzschild black hole to an ingoing gravitational wave by computing the Newman-Penrose (NP) constants. The NP…
