Charged black holes in Einsteinian cubic gravity and nonuniqueness
Antonia Micol Frassino, Jorge V. Rocha
Black holes are the simplest objects in the universe. They correspond to extreme deformations of spacetime geometry, and can exist even devoid of matter. In general relativity, (el…
Self-similar solutions and critical behavior in Einstein-Maxwell-dilaton theory sourced by charged null fluids
Pedro Aniceto, Jorge V. Rocha
We investigate continuously self-similar solutions of four-dimensional Einstein-Maxwell-dilaton theory supported by charged null fluids. We work under the assumption of spherical s…
Dynamical black holes in low-energy string theory
Pedro Aniceto, Jorge V. Rocha
We investigate time-dependent spherically symmetric solutions of the four-dimensional Einstein-Maxwell-axion-dilaton system, with the dilaton coupling that occurs in low-energy eff…
Smooth non-extremal D1-D5-P solutions as charged gravitational instantons
Bidisha Chakrabarty, Jorge V. Rocha, Amitabh Virmani
We present an alternative and more direct construction of the non-supersymmetric D1-D5-P supergravity solutions found by Jejjala, Madden, Ross and Titchener. We show that these sol…
Two worlds collide: Interacting shells in AdS spacetime and chaos
Richard Brito, Vitor Cardoso, Jorge V. Rocha
We study the simplest two-body problem in asymptotically anti-de Sitter spacetime: two, infinitely thin, concentric spherical shells of matter. We include only gravitational intera…
Radiating black holes in Einstein-Maxwell-dilaton theory and cosmic censorship violation
Pedro Aniceto, Paolo Pani, Jorge V. Rocha
We construct exact, time-dependent, black hole solutions of Einstein-Maxwell-dilaton theory with arbitrary dilaton coupling, . For this theory arises as the four-dimension…
