Revisiting near-extremal and near-BPS black holes in AdS3 supergravity
Adam Bac, Alejandra Castro, Diksha Jain
Despite the archetypal status of the BTZ background in quantifying quantum aspects of black holes, several features at low temperatures remain imprecise and incomplete. Here, we sy…
Near-extremal dynamics away from the horizon
Alejandra Castro, Robinson Mancilla, Ioannis Papadimitriou
Near-extremal black holes are usually studied by zooming into the throat that describes their near-horizon geometry. Within this throat, one can argue that two-dimensional JT gravi…
Quantum corrections to the path integral of near extremal de Sitter black holes
Matthew J. Blacker, Alejandra Castro, Watse Sybesma +1
We study quantum corrections to the Euclidean path integral of charged and static four-dimensional de Sitter (dS) black holes near extremality. These black holes admit three di…
Near-AdS Spectroscopy: classifying the spectrum of operators and interactions in 4D supergravity
Alejandra Castro, Evita Verheijden
We describe holographic properties of near-AdS spacetimes that arise within spherically symmetric configurations of 4D supergravity, for both gauged and u…
Rotating 5D Black Holes: Interactions and deformations near extremality
Alejandra Castro, Juan F. Pedraza, Chiara Toldo +1
We study a two-dimensional theory of gravity coupled to matter that is relevant to describe holographic properties of black holes with a single rotational parameter in five dimensi…
