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…

Causal structure of nonhomogeneous dust collapse in effective loop quantum gravity
MichaÅ Bobula, Tomasz PawÅowski
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
MichaÅ Bobula, Tomasz PawÅowski
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…
