# About Synchronized Globular Cluster Formation over Supra-galactic Scales

## TL;DR

This paper presents evidence that globular clusters formed in a synchronized manner across large cosmic scales, likely influenced by energetic events such as AGN activity and intense star formation in the early universe.

## Contribution

It introduces a novel pattern recognition approach revealing synchronized globular cluster formation over supra-galactic scales, challenging the view of purely stochastic cluster formation.

## Key findings

- Detection of color modulations in globular clusters across galaxy clusters
- Indication of non-stochastic, synchronized formation processes
- Evidence linking globular cluster formation to energetic cosmic events

## Abstract

Observational and theoretical arguments support the idea that violent events connected with $AGN$ activity and/or intense star forming episodes have played a significant role in the early phases of galaxy formation at high red shifts. Being old stellar systems, globular clusters seem adequate candidates to search for the eventual signatures that might have been left by those energetic phenomena. The analysis of the colour distributions of several thousands of globular clusters in the Virgo and Fornax galaxy clusters reveals the existence of some interesting and previously undetected features. A simple pattern recognition technique, indicates the presence of "colour modulations", distinctive for each galaxy cluster. The results suggest that the globular cluster formation process has not been completely stochastic but, rather, included a significant fraction of globulars that formed in a synchronized way and over supra-galactic spatial scales.
