Tides and energy conditions in Einstein-Gauss-Bonnet thin-shell wormholes
Ernesto F. Eiroa, Emilio Rubín de Celis, Claudio Simeone
In this article we study spherical thin-shell wormholes in five-dimensional Einstein-Gauss-Bonnet gravity. We show that configurations supported by non-exotic matter, that is matte…
Tides and traversability in gravastars and other related geometries
Cecilia Tomasini, Claudio Simeone, Emilio Rubín de Celis
Tidal effects related to the traversability across thin shells are examined in spherically symmetric geometries. We focus mainly on shells separating inner from outer regions of gr…
Sub-annular structure in black hole image from gravitational refraction
Gaston Giribet, Emilio Rubin de Celis, Pedro Schmied
The images of supermassive black holes captured by the Event Horizon Telescope (EHT) collaboration have allowed us to have access to the physical processes that occur in the vicini…
Thin shells joining local cosmic string geometries
Ernesto F. Eiroa, Emilio Rubin de Celis, Claudio Simeone
In this article we present a theoretical construction of spacetimes with a thin shell that joins two different local cosmic string geometries. We study two types of global manifold…
