Dynamical Singularity Resolution in Spherically Symmetric Black Hole Formation

TL;DR

This paper investigates how loop quantum gravity corrections influence scalar field collapse, revealing a mass gap, modified scaling, and singularity resolution with a remnant, advancing understanding of black hole formation.

Contribution

It introduces a quantum-corrected model of black hole formation that resolves singularities and predicts a remnant, extending classical collapse theories with quantum effects.

Findings

Presence of a mass gap in collapse outcomes

Modified Choptuik scaling with quantum dependence

Resolution of singularity with a remnant left behind

Abstract

We study numerically the effects of loop quantum gravity motivated corrections on massless scalar field collapse in Painlev\'e-Gullstrand coordinates. Near criticality, the system exhibits Choptuik scaling with the added features of a mass gap and a new scaling relationship dependant upon the quantum length scale. The quantum corrected collapse exhibits a radiation-like phase which resolves the singularity: the black hole consists of a compact region of space-time bounded by a single, smooth trapping horizon. The "evaporation" is not complete but leaves behind an outward moving remnant.
