Ultra slow-roll with a black hole
Lewis Croney, Ruth Gregory, Sam Patrick
We investigate ultra slow-roll inflation with a seed black hole in a de Sitter background. By numerically tracking transitions from slow-roll to ultra slow-roll inflation, we find…

On the origin of quasinormal modes in semi-open systems
Leonardo Solidoro, Sam Patrick, Ruth Gregory +1
Astrophysical black holes are open systems which, when perturbed, radiate quasi-normal modes (QNMs) to infinity. By contrast, laboratory analogues are necessarily finite-sized, pre…

Testing Higher Derivative Gravity Through Tunnelling
Ruth Gregory, Shi-Qian Hu
Higher derivative terms in the gravitational action are natural from the perspective of quantum gravity, but are perceived as leading to a lack of well-posedness. The Gauss Bonnet…
