Black Hole Remnants in the Early Universe

TL;DR

This paper explores how primordial micro black hole remnants could have influenced the early universe, potentially explaining anomalies in the CMB power spectrum through a matter-dominated epoch before inflation.

Contribution

It introduces a model where micro black hole remnants induce a matter-dominated era, affecting the CMB, and compares predictions with observational data to explain the quadrupole anomaly.

Findings

Model explains the CMB quadrupole anomaly

Primordial micro black holes induce early matter domination

Analytical and numerical analysis supports the model

Abstract

We consider the production of primordial micro black holes (MBH) remnants in the early universe. These objects induce the universe to be in a matter-dominated era before the onset of inflation. Effects of such an epoch on the CMB power spectrum are discussed and computed both analytically and numerically. By comparison with the latest observational data from the WMAP collaboration, we find that our model is able to explain the quadrupole anomaly of the CMB power spectrum.
