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…
Buchdahl limits in theories with regular black holes
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…
Regular black hole formation in four-dimensional non-polynomial gravities
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…
Regular black holes from Oppenheimer-Snyder collapse
Pablo Bueno, Pablo A. Cano, Robie A. Hennigar +2
It has been recently shown that regular black holes arise as the unique spherically symmetric solutions of broad families of generalizations of Einstein gravity involving infinite…
On regular charged black holes in three dimensions
Pablo Bueno, Oscar Lasso Andino, Javier Moreno +1
As argued in arXiv:2104.10172, introducing a non-minimally coupled scalar field, three-dimensional Einstein gravity can be extended by infinite families of theories which admit sim…
