Non-linear evolution of five-dimensional black strings in effective field theory
Pau Figueras, Áron D. Kovács, Shunhui Yao
We use numerical relativity to study the non-linear instability of five-dimensional black strings in Einstein-Gauss-Bonnet gravity. Black strings evolve into a series of black hole…

Stable non-linear evolution in regularised higher derivative effective field theories
Pau Figueras, Áron D. Kovács, Shunhui Yao
We study properties of a recently proposed regularisation scheme to formulate the initial value problem for general (relativistic) effective field theories (EFTs) with arbitrary hi…

GRFolres: A code for modified gravity simulations in strong gravity
Llibert Aresté Saló, Sam E. Brady, Katy Clough +6
GRFolres is an open-source code for performing simulations in modified theories of gravity, based on the publicly available 3+1D numerical relativity code GRChombo. Note: Submitted…
