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…
The balance problem for aligned black holes
Jörg Hennig
An intriguing open problem in general relativity is whether a stationary equilibrium configuration of multiple, physically relevant black holes can exist. In such a hypothetical se…
Soliton methods and the black hole balance problem
Jörg Hennig
This article is an extended version of a presentation given at KOZWaves 2024: The 6th Australasian Conference on Wave Science, held in Dunedin, New Zealand. Soliton methods were in…
Smooth Gowdy-symmetric generalised Taub-NUT solutions with polynomial initial data
Jörg Hennig
We consider smooth Gowdy-symmetric generalised Taub-NUT solutions, a class of inhomogeneous cosmological models with spatial three-sphere topology. They are characterised by existe…
