The realm of the galaxy protoclusters
R. A. Overzier

TL;DR
This review summarizes the current understanding of galaxy protoclusters, their properties, formation processes, and significance in cosmic evolution, highlighting recent findings, observational techniques, and future research directions.
Contribution
It provides a comprehensive overview of galaxy protoclusters, emphasizing their role in galaxy formation, early universe structure, and testing cosmological models, with insights from observations and simulations.
Findings
Protoclusters will evolve into present-day galaxy clusters.
Galaxies in protoclusters are among the first to transition to red sequence.
Protoclusters played a key role during the epoch of reionization.
Abstract
The study of galaxy protoclusters is beginning to fill in unknown details of the important phase of the assembly of clusters and cluster galaxies. This review describes the current status of this field and highlights promising recent findings related to galaxy formation in the densest regions of the early universe. We discuss the main search techniques and the characteristic properties of protoclusters in observations and simulations, and show that protoclusters will have present-day masses similar to galaxy clusters when fully collapsed. We discuss the physical properties of galaxies in protoclusters, including (proto-)brightest cluster galaxies, and the forming red sequence. We highlight the fact that the most massive halos at high redshift are found in protoclusters, making these objects uniquely suited for testing important recent models of galaxy formation. We show that galaxies in…
