再离子化镓（BoRG）简介
The Brightest of Reionizing Galaxies (BoRG) survey
摘要：
到目前为止，研究星系形成的早期阶段主要是理论建模和计算机模拟的领域，这需要许多物理成分，并且具有挑战性的观测测试。然而，哈勃太空望远镜在近红外线的最新观测正在为大爆炸后最初10亿年内的星系特性提供新的线索，包括我们最近发现的最遥远的原星系团，红移z~8。在这里，我比较原始和金属富集的恒星形成模型的预测在黑暗时代与最新的哈勃观测星系在再电离的时代。我特别关注的光度函数和星系团，从我们的哈勃太空望远镜Brilliance的Reionizing Galeries（BoRG）调查测量。BoRG拥有最大的区域覆盖范围，可以找到明亮和罕见的z~8源，这些源是宇宙中最早形成的星系之一。
英文摘要：
Until now, investigating the early stages of galaxy formation has been primarily the realm of theoretical modeling and computer simulations, which require many physical ingredients and are challenging to test observationally. However, the latest Hubble Space Telescope observations in the near infrared are shedding new light on the properties of galaxies within the first billion years after the Big Bang, including our recent discovery of the most distant proto-cluster of galaxies at redshift z~8. Here, I compare predictions from models of primordial and metal-enriched star formation during the dark ages with the latest Hubble observations of galaxies during the epoch of reionization. I focus in particular on the luminosity function and on galaxy clustering as measured from our Hubble Space Telescope Brightest of Reionizing Galaxies (BoRG) survey. BoRG has the largest area coverage to find luminous and rare z~8 sources that are among the first galaxies to have formed in the Universe.
