Mini Black Holes and the Relic Gravitational Waves Spectrum

TL;DR

This paper investigates how an early universe era dominated by mini black holes and radiation could significantly suppress the relic gravitational wave spectrum, affecting its detectability.

Contribution

It introduces a novel scenario of an early black hole-dominated era and analyzes its impact on the relic gravitational wave spectrum.

Findings

The era can reduce the gravitational wave spectrum by several orders of magnitude.

Mini black holes significantly influence the relic gravitational wave background.

The results suggest potential challenges for gravitational wave detection.

Abstract

In this paper we explore the impact of an era -right after reheating- dominated by mini black holes and radiation on the spectrum of the relic gravitational waves. This era may lower the spectrum several orders of magnitude.
