Thin shells in (2+1)-dimensional F(R) gravity
Ernesto F. Eiroa, Griselda Figueroa-Aguirre
We study thin shells of matter in (2+1)-dimensional F(R) theories of gravity with constant scalar curvature R. We consider a wide class of spacetimes with circular symmetry, in whi…

Thin shells in F(R) gravity with non-constant scalar curvature
Ernesto F. Eiroa, Griselda Figueroa-Aguirre
We introduce two classes of spherically symmetric spacetimes having a thin shell of matter, in non-quadratic F(R) theories of gravity with non-constant scalar curvature R. In the f…

Influence of an anisotropic matter field on the shadow of a rotating black hole
Javier Badía, Ernesto F. Eiroa
In this paper, we study the shadow produced by rotating black holes with charge in the presence of an anisotropic matter field. We obtain the apparent shape and the corresponding o…
