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…

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…

Challenges in the nonlinear evolution of unequal mass binaries in sGB gravity
Llibert Aresté Saló, Daniela D. Doneva, Katy Clough +2
It has only recently become possible to simulate the full nonlinear dynamics of binary black holes in scalar-Gauss-Bonnet theories of gravity. The simulations remain technically ch…
