Based on a previously found general class of quantum improved exact solutions composed of non-interacting (dust) particles, we model the gravitational collapse of stars. As the modeled star collapses a closed apparent 3-horizon is generated due to th

Els estudis d'Arquitectura tenen com a espina dorsal la metodologia activa de l'aprenentatge basat en projectes (ABP). "Aprendre fent projectes" entronca amb la metodologia que s'està implementant als entorns d'aprenentatge dels cicles d'educació i

We analyse the physical implications of the energy and matching conditions that take part in the construction of spherically symmetric models for stars and voids. We find an important condition on the radial pressures that can be of relevance, for in

We study the matching of a general spherically symmetric spacetime with a Vaidya-Reissner-Nordstrom solution. To that end, we study the properties of spherically symmetric electromagnetic fields and develop the proper gravitational and electromagneti

We model the gravitational collapse of heavy massive shells including its main quantum corrections. Among these corrections, quantum improvements coming from Quantum Einstein Gravity are taken into account, which provides us with an effective quantum

In this paper we study the electromagnetic fields generated by a Killing vector field in vacuum space-times (Papapetrou fields). The motivation of this work is to provide new tools for the resolution of Maxwell's equations as well as for the search,

In this paper we show some very general results concerning the general matching of any two spherically symmetric spacetimes through a timelike hypersurface. We present a set of necessary conditions for this case which are very simple to use. As an im

A revision of Israel's extension of Vaidya's spacetime is proposed in order to apply the procedure to more general spacetimes. Israel's procedure is reformulated to obtain the extension even if the only available function is the mass in the non-exten
