Spherical thin shells with charge in unimodular gravity
Gabriel R. Bengochea, Ernesto F. Eiroa, Griselda Figueroa-Aguirre
We construct spherically symmetric thin shells in unimodular gravity (UG) and analyze their dynamical stability under radial, symmetry-preserving perturbations. We use the UG junct…
Entropy and stability of an extremally charged Einstein-Born-Infeld thin shell
Ernesto Eiroa, Griselda Figueroa-Aguirre, Miguel Peñafiel
Spacetimes with a thin shell offer a framework where both the dynamical and the thermodynamical stability of the matter comprising the shell can be consistently studied. In the pre…
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…
Stability of spherical thin-shell wormholes in scalar-tensor theories
Ernesto F. Eiroa, Griselda Figueroa-Aguirre, Vasiliki Karanasou
In this article, we construct a family of spherically symmetric thin-shell wormholes within scalar-tensor theories of gravity. In the case of wormholes symmetric across the throat,…
Shadows cast by a class of rotating black bounces with an anisotropic fluid
Ernesto F. Eiroa, Juan M. Paez
In this work, we introduce a family of rotating black bounces with an anisotropic fluid obtained by using a modified Newman-Janis algorithm. We analyze the main features of these s…
Charged thin shells in unimodular gravity
Gabriel R. Bengochea, Ernesto F. Eiroa, Griselda Figueroa-Aguirre
In this article, we construct a broad family of spacetimes with spherically symmetric thin shells in unimodular gravity. We present the framework for the analysis of the dynamical…
