Regular (nonsingular) space-times are given that describe the formation of a (locally defined) black hole from an initial vacuum region, its quiescence as a static region, and its subsequent evaporation to a vacuum region. The static region is Bardeen-like, supported by finite density and pressures, vanishing rapidly at large radius and behaving as a cosmological constant at small radius. The dynamic regions are Vaidya-like, with ingoing radiation of positive-energy flux during collapse and negative-energy flux during evaporation, the latter balanced by outgoing radiation of positive-energy flux and a surface pressure at a pair creation surface. The black hole consists of a compact space-time region of trapped surfaces, with inner and outer boundaries that join circularly as a single smooth trapping horizon.read more

On Continued Gravitational Contraction
TL;DR: In this paper, the authors study the solutions of the gravitational field equations which describe the contraction of a heavy star, and give general and qualitative arguments on the behavior of the metrical tensor as the contraction progresses.

Rotating regular black holes
Cosimo Bambi,Leonardo Modesto +1 more
TL;DR: In this paper, the Newman-Janis algorithm was applied to the Hayward and the Bardeen metrics to obtain a family of rotating solutions with a minimal violation of the weak energy condition and without the questionable property of the curvature invariants at the origin.

Black Hole Remnants and the Information Loss Paradox
TL;DR: In this paper, the authors provide a review of various types of black hole remnants, and provide some new thoughts regarding the challenges that black hole survivors face in the context of the information loss paradox and its latest incarnation, namely the firewall controversy.

Planck stars
Carlo Rovelli,Francesca Vidotto +1 more
TL;DR: The existence of these objects alleviates the black-hole information paradox as discussed by the authors, and these objects could have astrophysical and cosmological interest: they produce a detectable signal, of quantum gravitational origin, around the $10^{-14} cm$ wavelength.

Spacetime structure of an evaporating black hole in quantum gravity
Alfio Bonanno,Martin Reuter +1 more
TL;DR: In this paper, the impact of the leading quantum gravity effects on the dynamics of the Hawking evaporation process of a black hole is investigated, and its spacetime structure is described by a renormalization group improved Vaidya metric.

Particle Creation by Black Holes
TL;DR: In this article, it is shown that quantum mechanical effects cause black holes to create and emit particles as if they were hot bodies with temperature, which leads to a slow decrease in the mass of the black hole and to its eventual disappearance.

Singular hypersurfaces and thin shells in general relativity
TL;DR: In this article, an approach to study the dynamics of thin shells of dust in general relativity is presented. But no mention of admissible or even any space-time co-ordinates is needed.

Breakdown of Predictability in Gravitational Collapse
TL;DR: In this paper, it is shown that the ignorance principle holds for the quantum-mechanical evaporation of black holes, where the black hole creates particles in pairs, with one particle always falling into the hole and the other possibly escaping to infinity.

The Singularities of gravitational collapse and cosmology
Stephen W. Hawking,Roger Penrose +1 more
TL;DR: In this article, a new theorem on space-time singularities is presented which largely incorporates and generalizes the previously known results and applies if the universe is spatially closed or there is an object undergoing relativistic gravitational collapse (existence of a trapped surface).
