The most distant galaxies: probing the early universe

从银河系发出的强大射电辐射表明 中心超大质量黑洞，是最有效的 在宇宙边缘发现星系。通过使用数据挖掘 关于我们现有的南方低频无线电图像的技术 天空，我们将确定80-100个最年轻和最遥远的大质量 星系，这是迄今为止组装的最大的此类样本。会是 用于测量超大质量黑洞随时间的增长，以及 来检验关于大质量星系如何在早期形成的相互竞争的理论 宇宙。

Powerful radio emission from a galaxy points to the presence of a central supermassive black hole, and is the most effective tool for finding galaxies at the edge of the universe. By using data mining techniques on our existing low-frequency radio images of the southern sky, we will identify 80-100 of the youngest and most distant massive galaxies, by far the largest such sample ever assembled. It will be used to measure the growth of supermassive black holes over time, and to test competing theories of how massive galaxies formed in the early universe.
