Holographic thermodynamics of accelerating black holes (2018)
Journal Article
Anabalón, A., Appels, M., Gregory, R., Kubizňák, D., Mann, R. B., & Övgün, A. (2018). Holographic thermodynamics of accelerating black holes. Physical Review D, 98(10), Article 104038. https://doi.org/10.1103/physrevd.98.104038

We present a careful study of accelerating black holes in anti-de Sitter spacetime, formulating the thermodynamics and resolving discrepancies that have appeared in previous investigations of the topic. We compute the dual stress-energy tensor for th... Read More about Holographic thermodynamics of accelerating black holes.

Negative modes of Coleman–De Luccia and black hole bubbles (2018)
Journal Article
Gregory, R., Marshall, K. M., Florent, M., & Moss, I. G. (2018). Negative modes of Coleman–De Luccia and black hole bubbles. Physical Review D, 98(8), Article 085017. https://doi.org/10.1103/physrevd.98.085017

We study the negative modes of gravitational instantons representing vacuum decay in asymptotically flat space-time. We consider two different vacuum decay scenarios: the Coleman-de Luccia O(4)- symmetric bubble, and Oð3Þ × R instantons with a static...

Evolving black holes in inflation (2018)
Journal Article
Gregory, R., Kastor, D., & Traschen, J. (2018). Evolving black holes in inflation. Classical and Quantum Gravity, 35(15), Article 155008. https://doi.org/10.1088/1361-6382/aacec2

We present an analytic, perturbative solution to the Einstein equations with a scalar field that describes dynamical black holes in a slow-roll inflationary cosmology. We show that the metric evolves quasi-statically through a sequence of Schwarzschi... Read More about Evolving black holes in inflation.
