Description

I will explore the semiclassical scenario of fluid collapse with pressure in a framework of Loop Quantum Gravity.
It is shown, consistently with already existent models, that the singularity is replaced by a bounce occurring in the Planckian regime. However, it is seen that the presence of pressure does not prevent the formation of shell crossing singularities which feature the non-homogeneous dust collapse.
The model is studied both semi-analytically, in a simplified case, and numerically in a more general and realistic scenario.
