Preheating and oscillon formation in Einstein-scalar-Gauss-Bonnet gravity
Areef Waeming, Josu C. Aurrekoetxea, Katy Clough +2
Non-perturbative processes in the early universe may create overdense structures in scalar fields like the inflaton, called oscillons. In this work, we explore whether the leading…
The initial data of effective field theories of relativistic viscous fluids and gravity
Lorenzo Gavassino, Ãron D. Kovács, Harvey S. Reall
There has been recent progress in developing well-posed theories of relativistic viscous hydrodynamics and of gravitational effective field theories. These have in common the featu…
Non-linear evolution of five-dimensional black strings in effective field theory
Pau Figueras, Ãron 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…
You've got a Freund--Rubin in Me: The Aretakis Instability of Extremal Black Branes
Calvin Y. -R. Chen, Ãron D. Kovács
We investigate how the Aretakis instability affects non-dilatonic extremal black -branes by focusing on their near-horizon geometry. Crucially, the strength of the instability,…
