Very compact objects probe extreme gravitational fields and may be the key to understand
outstanding puzzles in fundamental physics. These include the nature of dark matter, the …

An outstanding open issue in our quest for physics beyond Einstein is the unification of
general relativity (GR) and quantum physics. Loop quantum gravity (LQG) is a leading …

Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

We present a new effective description of macroscopic Kruskal black holes that incorporates
corrections due to quantum geometry effects of loop quantum gravity. It encompasses both …

A bstract We reformulate recent insights into black hole information in a manner
emphasizing operationally-defined notions of entropy, Lorentz-signature descriptions, and …

While singularities are inevitable in the classical theory of general relativity, it is commonly
believed that they will not be present when quantum gravity effects are taken into account in …

A new description of macroscopic Kruskal black holes that incorporates the quantum
geometry corrections of loop quantum gravity is presented. It encompasses both the …

The 1965 Penrose singularity theorem demonstrates the utterly inevitable and unavoidable
formation of spacetime singularities under physically reasonable assumptions, and it …

We study the quantum dynamics of the Lemaître-Tolman-Bondi space-times using a polymer
quantization prescription based on loop quantum cosmology that incorporates fundamental …

We write explicitly the complete Lorentzian metric of a singularity-free spacetime where a
black hole transitions into a white hole located in its same asymptotic region. In particular …
