Phase Transitions and Black Hole Stability in Gauged N = 8 Supergravity
Andres Anabalon, Dumitru Astefanesei, Julio Oliva +2
It is well known that there is a region of parameter space where all purely electric, static, dilatonic black holes are unstable within the STU models of maximal supergravity. We s…
Thermal superpotential and thermodynamics of neutral hairy black holes in extended SUGRA
Andrès Anabalòn, Dumitru Astefanesei, David Choque +1
We present a family of exact neutral hairy black-hole solutions with spherical horizon topology in extended supergravity with Fayet--Iliopoulos terms. We consider a consistent dila…
Virtual work, thermodynamic structure of the spacetime, and black hole criticality
Dumitru Astefanesei, Gonzalo Casanova, Raul Rojas
We propose a new way to relate the black hole thermodynamics and geometry by generalizing the Euclidean formalism to include "virtual geometries", which do not necessarily satisfy…
(Quasi-)normal modes of rotating black holes and new solitons in Einstein-Gauss-Bonnet
Lilianne Tapia, Monserrat Aguayo, Andrés Anabalón +5
In this paper, we analyze the scalar field (quasi-)normal modes of recently derived rotating black holes within the framework of Einstein-Gauss-Bonnet theory at the Chern-Simons po…
On the existence of thermodynamically stable asymptotically flat black holes
Dumitru Astefanesei, Romina Ballesteros, Paulina Cabrera +2
We use the quasilocal formalism of Brown and York, supplemented with counterterms, to investigate the thermodynamics of asymptotically flat black holes. We consider two families of…
Rotating and accelerating AdS black holes in Einstein-Gauss-Bonnet Gravity
Andres Anabalon, Dumitru Astefanesei, Adolfo Cisterna +4
We present new, exact, rotating and accelerating solutions within the framework of five-dimensional Einstein-Gauss-Bonnet theory at the Chern-Simons point. The rotating solutions d…
