Thin-Shell Black Bounce
Leandro A. Lessa, Renan B. Magalhães, Gonzalo J. Olmo
A recently proposed class of black-bounce solutions sourced by anisotropic fluids, whose exterior reproduces the Reissner-Nordström geometry all the way down to a minimal-area boun…
Periodic equatorial orbits in a black bounce scenario
Anderson Bragado, Gonzalo J. Olmo
We study equatorial closed orbits in a popular black bounce model to see if the internal structure of these objects could lead to peculiar observable features. Paralleling the anal…
Singular space-times with bounded algebraic curvature scalars
Renan B. Magalhães, Gabriel P. Ribeiro, Haroldo C. D. Lima Junior +2
We show that the absence of unbounded algebraic curvature invariants constructed from polynomials of the Riemann tensor cannot guarantee the absence of strong singularities. As a c…
Echoes from bounded universes
Renan B. Magalhães, Andreu Masó-Ferrando, Flavio Bombacigno +2
We construct a general class of modified Ellis wormholes, where one asymptotic Minkowski region is replaced by a bounded 2-sphere core, characterized by asymptotic finite areal rad…
Numerical evolutions of boson stars in Palatini gravity
Andreu Masó-Ferrando, Nicolas Sanchis-Gual, José A. Font +1
We investigate the time evolution of spherically symmetric boson stars in Palatini gravity through Numerical Relativity computations. Employing a novel approach th…
