Thin shells in Lovelock and Quasi-topological gravities
Pablo Bueno, Pablo A. Cano, Robie A. Hennigar +2
We derive the junction conditions for spherically symmetric thin shells in Lovelock and Quasi-topological gravities along two independent routes: from the distributional form of th…
Quasinormal modes and quantum black hole interiors
Chiara Coviello, Ansh Gupta, Robie A. Hennigar +2
Quasinormal modes (QNMs) of black hole perturbations in the large overtone limit, namely, asymptotic QNMs, are highly sensitive to a black hole's interior geometry. We probe the si…
Looking inside a quantum black hole
Chiara Coviello, Ansh Gupta, Robie A. Hennigar +2
Quantum effects are expected to modify a black hole's interior structure, particularly near the singularity. We show how to extract the scaling exponent of the singularity from the…
Logarithmic correction to the entropy of near-extremal higher-curvature black holes
Pablo Bueno, Pablo A. Cano, Robie A. Hennigar +3
The spherically symmetric sector of broad classes of -dimensional gravitational theories can be effectively described by general two-dimensional Horndeski theories. Exploiting t…

Pablo Bueno, Pablo A. Cano, Robie A. Hennigar +1
We present infinite-derivative completions of Quasitopological gravities that are ghost-free, avoid strong coupling instabilities and admit exact, spherically symmetric vacuum regu…

We construct geometries describing the quantum backreaction of thermal fields in AdS. The solutions are obtained from branes in a four-dimensional AdS C-metric. They can be vie…
Regular Geometries from Singular Matter in Quasi-Topological Gravity
Pablo Bueno, Robie A. Hennigar, Ángel J. Murcia +1
Vacuum quasi-topological gravity with infinitely many terms in the action satisfies Markov's limiting curvature hypothesis: the spherically symmetric solutions are regular and all…

Pablo Bueno, Robie A. Hennigar, Ángel J. Murcia +1
We study generalizations of Buchdahl's compactness limits for perfect-fluid star solutions of -dimensional Einstein gravity coupled to higher-curvature corrections. We focus on…
Birkhoff implies Quasi-topological
Pablo Bueno, Robie A. Hennigar, Ángel J. Murcia
Quasi-topological gravities (QTGs) are higher-curvature extensions of Einstein gravity in spacetime dimensions. Throughout the years, different notions of QTGs constructe…

Pablo Bueno, Pablo A. Cano, Robie A. Hennigar +1
We construct four-dimensional gravity theories that resolve the Schwarzschild singularity and enable dynamical studies of nonsingular gravitational collapse. The construction emplo…

We construct exact solutions that describe the near horizon region of extremal rotating black holes in Einstein-Born-Infeld theory. Using generalized Komar integrals, we extract th…

We investigate the thermodynamic and holographic properties of charged and rotating quantum black holes in a doubly holographic braneworld setup. These quantum black holes are deri…

Tomáš Hale, Robie A. Hennigar, David Kubiznak
Charged and/or rotating black holes in General Relativity feature Cauchy horizons, which indicate a breakdown of predictability in the theory. Focusing on spherically symmetric cha…

Kasner eons in Lovelock black holes
Pablo Bueno, Pablo A. Cano, Robie A. Hennigar +1
In the vicinity of space-like singularities, general relativity predicts that the metric behaves, at each point, as a Kasner space which undergoes a series of "Kasner epochs" and "…
Evolution of creases on the event horizon of a black hole merger
Maxime Gadioux, Robie A. Hennigar, Harvey S. Reall
A generic black hole merger occurs through a restructuring of creases (sharp edges) on the event horizon. This process is studied for a black hole merger in the limit of infinite m…
