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…
Parametrized black holes: Scattering investigation
Renan B. Magalhães, Luiz C. S. Leite, Luís C. B. Crispino
We study the scattering of light-like geodesics and massless scalar waves by a static Konoplya-Zhidenko black hole, considering the case that the parametrized black hole solution c…
Asymmetric wormholes in Palatini gravity: Energy conditions, absorption and quasibound states
Renan B. Magalhães, Andreu Masó-Ferrando, Gonzalo J. Olmo +1
We investigate the absorption properties of reflection-asymmetric wormholes constructed via the thin-shell formalism in Palatini gravity. Such wormholes come from the…
