Regular Schwarzschild black holes and cosmological models
Roberto Casadio, Alexander Kamenshchik, Jorge Ovalle
We study regular Schwarzschild black holes in General Relativity as an alternative to the singular counterpart. We analyze two types of solutions which are completely parameterised…

Analytic models for gravitational collapse
Sinya Aoki, Jorge Ovalle
We present two analytical models of gravitational collapse toward the Schwarzschild black hole, starting from the interior of the revisited Schwarzschild solution recently reported…

Decoupling gravitational sources in general relativity: the extended case
J Ovalle
We show how to decoupling two spherically symmetric and static gravitational sources through the most general possible extension of the so-called Minimal Geometric Deformation-deco…
