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…

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…
