# High-redshift Mini-haloes from Modulated Preheating

## TL;DR

This paper explores how primordial non-Gaussian fluctuations from modulated preheating can lead to an excess of mini-haloes at high redshift, potentially influencing early supermassive black hole formation.

## Contribution

It introduces a novel mechanism linking modulated preheating-induced non-Gaussianity to mini-halo overabundance at high redshift.

## Key findings

- Overproduction of mini-haloes with masses around 10^8 solar masses at z > 20.
- Potential implications for the formation of high-redshift supermassive black holes.
- Highlights a new connection between early universe fluctuations and structure formation.

## Abstract

Intermittent type of primordial non-Gaussian fluctuations from modulated preheating can produce an overabundance of $\sim 10^8M_\odot$ mini-haloes at high redshift $z\gtrsim 20$. This may have a significant impact on the formation of high-redshift supermassive black holes.
