Many models in which the object under study loses all its mass have appeared in the literature. No doubt, the most eminent examples are the models for evaporating black holes and for evaporating stars. Here we describe ...

En aquest llibre s’ofereix una introducció moderna al càlcul estructural. Es pretén que les noves generacions d’arquitectes coneguin des dels primers cursos, d’una banda, els fonaments de la ciència que són aplicables a ...

It is argued that primordial black holes with initial masses satisfying M<1015 g, instead of having explode, might currently be in a quasistable phase contributing to a tiny fraction of the measured dark matter. This ...

Quantum gravitational effects in black hole spacetimes with a cosmological constant ¿ are considered. The effective quantum spacetimes for the black holes are constructed by taking into account the renormalization group ...

We claim that imposing energy conservation to the emission of Hawking radiation and to the modeling of black hole (BH) evaporation might prevent BH explosions as well as violations of the third law of BH thermodynamics. ...

The causal character of singularities is often studied in relation to the existence of naked singularities and the subsequent possible violation of the cosmic censorship conjecture. Generally, one constructs a model in the ...

We provide a general formalism that allows to analyze the phenomenon of tunneling in arbitrary spacetimes. We show that a flux of particles produced by tunneling through general marginally trapped surfaces may be perceived ...

A general class of quantum improved stellar models with interiors composed of non-interacting (dust) particles is obtained and analyzed in a framework compatible with asymptotic safety. First, the effective exterior, based ...
