We derive effective equations with loop quantum gravity corrections for the Lemaître–
Tolman–Bondi family of space-times, and use these to study quantum gravity effects in the …

We investigate the fate of the classical singularity in a collapsing dust cloud. For this
purpose, we quantize the marginally bound Lemaître-Tolman-Bondi model for spherically …

We consider Lemaitre-Tolman-Bondi spacetimes from the point of view of a tilted observer,
ie one with respect to which the fluid is radially moving. The imperfect fluid and the …

We obtain covariant expressions that generalize the growing and decaying density modes of
linear perturbation theory of dust sources by means of the exact density perturbation from …

Marginal Lemaitre-Tolman-Bondi (LTB) models with corrections from loop quantum gravity
have recently been studied with an emphasis on potential singularity resolution. This paper …

We study fluid distributions endowed with hyperbolic symmetry, which share many common
features with Lemaitre–Tolman–Bondi (LTB) solutions (eg, they are geodesic, shearing, and …

We consider extensions of Lemaitre-Tolman-Bondi (LTB) spacetimes to the dissipative case.
We have previously carried out a systematic study on LTB. This study is based on two …

Lemaitre-Tolman-Bondi models as specific spherically symmetric solutions of general
relativity simplify in their reduced form some of the mathematical ingredients of black hole or …

We present a consistent canonical formulation of the flat Oppenheimer-Snyder model,
including the Schwarzschild exterior. The switching between comoving and stationary …

We review the spherically symmetric sector of General Relativity and its midisuperspace
quantization using Loop Quantum Gravity techniques. We exhibit anomaly-free deformations …
