The First Objects in the Universe

对宇宙微波背景辐射的观测表明，早期宇宙是一个光滑而简单的，含有中性气体成分的宇宙。这与局部宇宙形成对比，局部宇宙是复杂和不均匀的电离星系际气体。在宇宙年龄的前5-10%期间导致这种转变的过程的研究是现代宇宙学中最重要的主题之一。这个发现项目将侧重于早期宇宙中关键天体物理过程的理论描述。这项研究将通过大量新的望远镜来补充和指导这个新时代的观测。

Observations of the Cosmic Microwave Background show a smooth and simple early universe with a neutral gas component. This is in contrast to the local universe which is complex and inhomogeneous with ionized intergalactic gas. The study of the processes leading to this transformation during the first 5-10% of the universes age is one of the most important topics in modern cosmology. This Discovery Project will focus on a theoretical description of the key astrophysical processes in the early universe. The research will compliment and be guided by observations of this facinating era by the raft of new telescopes becoming available.
