Black Holes Without Singularities

TL;DR

This paper introduces a singularity-free black hole model in two-dimensional dilaton gravity, achieved through a completely integrable deformation of the CGHS model, which behaves like the original at large distances.

Contribution

It presents a novel integrable deformation of the CGHS model resulting in a black hole solution without singularities, extending the understanding of black hole models in lower dimensions.

Findings

The deformed model describes a singularity-free black hole.

At large distances, the solution asymptotically matches the CGHS black hole.

The model maintains integrability and physical consistency.

Abstract

We study the properties of a completely integrable deformation of the CGHS dilaton gravity model in two dimensions. The solution is shown to represent a singularity free black hole that at large distances asymptoticaly joins to the CGHS solution.
