Asymmetric Quantum Oppenheimer-Snyder Collapse
Michał Bobula, Tomasz Pawłowski
We study black hole formation resulting from the collapse of a homogeneous and isotropic dust ball within a framework built upon loop quantum cosmology. Using loop dynamics formula…
Quantum gravitational stellar evolution beyond shell-crossing singularities
Michał Bobula, Francesco Fazzini
Models of effective stellar collapse inspired by loop quantum gravity predict a bounce when the stellar energy density reaches the Planck scale, typically followed by the formation…
Causal structure of nonhomogeneous dust collapse in effective loop quantum gravity
Michał Bobula, Tomasz Pawłowski
We study the causal structure for spherically symmetric dust collapse within a model of effective loop quantum gravity in midisuperspace framework. We develop a general strategy (w…
Quantum dust collapse with cosmological constant and methods for constructing conformal diagrams
Michał Bobula, Tomasz Pawłowski
The loop quantum gravitational collapse of the dust ball in presence of positive cosmological constant is investigated within the Oppenheimer-Snyder collapse scenario. The dust bal…
Cosmic inflation prevents singularity formation in collapse into a Hayward black hole
Michał Bobula
We construct a (quantum mechanically) modified model for the Oppenheimer-Snyder collapse scenario where the exterior of the collapsing dust ball is a Hayward black hole spacetime a…
Rainbow Oppenheimer-Snyder collapse and the entanglement entropy production
Michał Bobula, Tomasz Pawłowski
The dust ball collapse is studied in the context of the "rainbow metric" approach (where the matter content is supplemented with a scalar field perturbation) to the Oppenheimer-Sny…
