Isotropization and change of complexity by gravitational decoupling
R. Casadio, E. Contreras, J. Ovalle +2
We employ the gravitational decoupling approach for static and spherically symmetric systems to develop a simple and powerful method in order to a) continuously isotropize any anis…
Minimal Geometric Deformation in a Reissner-Nordström background
Angel Rincon, Luciano Gabbanelli, Ernesto Contreras +1
This article is devoted to the study of new exact analytical solutions in the background of Reissner-Nordström space-time by using gravitational decoupling via minimal geometric de…
Gravitational Decoupling in Cosmology
Francisco X. Linares Cedeño, Ernesto Contreras
Whereas the nature of dark components in the Universe remains unknown, alternative models of gravity have been developed to offer a geometric explanation to the origin of such comp…
Black hole shadow of a rotating scale--dependent black hole
Ernesto Contreras, Ángel Rincón, Grigoris Panotopoulos +2
In this work, starting from a spherically symmetric scale--dependent black hole, a rotating solution is obtained by following the Newman--Janis algorithm without complexification.…
Black hole shadow of a rotating polytropic black hole by the Newman--Janis algorithm without complexification
E. Contreras, J. M. Ramirez-Velasquez, Á. Rincón +2
In this work, starting from a spherically symmetric polytropic black hole, a rotating solution is obtained by following the Newman--Janis algorithm without complexification. Beside…
All static spherically symmetric anisotropic solutions for general relativistic polytropes
G. Abellán, P. Bargueño, E. Contreras +1
An algorithm presented by K. Lake to obtain all static spherically symmetric perfect fluid solutions was recently extended by L. Herrera to the interesting case of locally anisotro…
