Singularity free gravitational collapse in an effective dynamical quantum spacetime

Understand

We model the gravitational collapse of heavy massive shells including its main quantum corrections.

• Among these corrections, quantum improvements coming from Quantum Einstein Gravity are taken into account, which provides us with an effective quantum spacetime.
• Likewise, we consider dynamical Hawking radiation by modeling its back-reaction once the horizons have been generated.
• Our results point towards a picture of gravitational collapse in which the collapsing shell reaches a minimum non-zero radius (whose value depends on the shell initial conditions) with its mass only slightly reduced.
