Diffuse emission from black hole remnants

General Relativity and Quantum Cosmology 2023-05-05 v2 High Energy Physics - Theory

Abstract

We point out that conservation of information implies that remnants produced at the end of black hole evaporation should radiate in the low-frequency spectrum. We model this emission and derive properties of the diffuse radiation emitted by an otherwise dark population of such objects. We show that for early universe black holes the frequency and energy density of this radiation, which are in principle measurable, suffice to estimate the remnant density.
