Internal structure of a Maxwell-Gauss-Bonnet black hole

TL;DR

This paper investigates how the Maxwell field affects the internal structure of a Gauss-Bonnet black hole, revealing that high charge levels can change the nature of inner singularities.

Contribution

It provides numerical evidence that increasing charge in a Maxwell-Gauss-Bonnet black hole alters its internal singularity structure, introducing a singular horizon.

Findings

Inner determinant singularity replaced by a singular horizon at high charge

Numerical simulations demonstrate the impact of charge on black hole interior

The structure transition depends on the charge exceeding a critical value

Abstract

The influence of the Maxwell field on a static, asymptotically flat and spherically-symmetric Gauss-Bonnet black hole is considered. Numerical computations suggest that if the charge increases beyond a critical value, the inner determinant singularity is replaced by an inner singular horizon.
