Abstract

The distant ancestors of local galaxy clusters, known as 'proto-clusters', are powerful laboratories for tracing the emergence of large-scale structure and studying the formation of galaxies in dense environments. However proto-clusters are rare and diffuse, so locating them poses a significant observational challenge. I will present recent advances in detecting proto-clusters that have allowed us to increase the number of known structures by an order of magnitude in just a few years. In this seminar, I will show how these proto-clusters shed light on the formation of massive galaxies early in the Universe, and highlight the importance of environment in driving galaxy evolution.
