Phenomenology of bouncing black holes in quantum gravity: a closer look

TL;DR

This paper explores the astrophysical signals of bouncing black holes, particularly primordial ones, in quantum gravity, analyzing how different bounce times affect the diffuse emission observed.

Contribution

It provides a detailed analysis of the potential observable signatures of bouncing black holes in quantum gravity, focusing on primordial black holes and varying bounce times.

Findings

Different bounce times influence the diffuse emission spectrum.

Primordial bouncing black holes could produce detectable astrophysical signals.

The study offers predictions for future observational tests.

Abstract

It was recently shown that black holes could be bouncing stars as a consequence of quantum gravity. We investigate the astrophysical signals implied by this hypothesis, focusing on primordial black holes. We consider different possible bounce times and study the integrated diffuse emission.
