Extending the frontier of galaxy studies in the epoch of reionization

该项目将研究宇宙大爆炸后最初3 -6亿年内最远的原星系团中的恒星形成，并将哈勃太空望远镜的观测结果与计算机模拟和理论建模相结合。该项目将描述关于第一个星系的起源和演化的基本开放问题，并探测宇宙再电离及其拓扑结构。它将为射电望远镜（包括研究星系间介质的平方公里阵列）提供一套补充观测，并为观测将在今天的宇宙中演变成大质量星系团的系统铺平道路。

This project will study star formation in the farthest protoclusters of galaxies, within the first 300-600 million years after the Big Bang, combining ongoing Hubble Space Telescope observations with computer simulations and theoretical modelling. This project will characterise fundamental open questions on the origin and evolution of the first galaxies and probe cosmic reionization and its topology. It will provide a set of observations complementary to those with radio telescopes, including the Square Kilometre Array that studies the intergalactic medium, and pave the way for observations of systems that will evolve into massive galaxy clusters in today's Universe.
