Black hole-wormhole collisions and the emergence of islands
João M. Dias, Antonia M. Frassino, Valentin D. Paccoia +1
We use ray-tracing techniques to determine the evolution of the event horizon of a large black hole that ``gobbles'' a tiny, traversable wormhole. This calculation has physical mea…
Self-similarity in Einstein-Maxwell-dilaton theories and critical collapse
Jorge V. Rocha, Marija Tomašević
We study continuously self-similar solutions of four-dimensional Einstein-Maxwell-dilaton theory, with an arbitrary dilaton coupling. Self-similarity is an emergent symmetry of gra…
Scanning the parameter space of collapsing rotating thin shells
Jorge V. Rocha, Raphael Santarelli
We present results of a comprehensive study of collapsing and bouncing thin shells with rotation, framing it in the context of the weak cosmic censorship conjecture. The analysis i…
Collapsing shells, critical phenomena and black hole formation
Vitor Cardoso, Jorge V. Rocha
We study the gravitational collapse of two thin shells of matter, in asymptotically flat spacetime or constrained to move within a spherical box. We show that this simple two-body…
Geodesic motion in equal angular momenta Myers-Perry-AdS spacetimes
Térence Delsate, Jorge V. Rocha, Raphael Santarelli
We study the geodesic motion of massive and massless test particles in the background of equally spinning Myers-Perry-anti-de Sitter (AdS) black holes in five dimensions. By adopti…
Greybody factors for rotating black holes in higher dimensions
Rogério Jorge, Ednilton S. de Oliveira, Jorge V. Rocha
We perform a thorough study of greybody factors for minimally-coupled scalar fields propagating on the background of rotating black holes in higher (odd) dimensions with all angula…
