This research is aimed at undertaking and answering fundamental questions about the universe and its history. At the same time we will develop new techniques and instruments to help answer future questions. We address many of the frontier questions in astrophysics. These include: how did the universe get to be how it is? What were the processes that led to the development of the largest structures in the universe? What were the seed conditions that led to galaxies and clusters of galaxies existing today? We can study these questions by looking at the Cosmic Microwave Background Radiation (CMBR), radio waves which were emitted soon after the 'Big Bang'. Part of our work is to study the waves to find the imprints of structure formed in the first fraction of a second of the universe's existence. We can also find the earliest forming clusters of galaxies by looking for the 'shadows' they cast on the CMBR. Big advances in astronomy come from the introduction of new techniques, and we want to continue to pioneer the application of the technique of interferometry. This imaging technique was initially developed in our group of radio astronomy, but we are now developing it for astronomy at visible wavelengths. This work will complete the development of an interferometer which will be able to see details in stars and the centres of galaxies which cannot be seen in any other way. We also aim to advance the use of interferometry in radio astronomy by developing techniques to allow interferometric telescopes to observe more of the sky at a given time. This has applications in a wide range of astronomy research. We aim to answer fundamental questions about how stars are formed, by using instruments which can see large numbers of stars at early stages of formation. We also plan to use telescopes which are coming on line in the next few years to see the formation of stars and planets in other solar systems in unprecedented detail. By using data from recently developed telescopes, we will start looking at how magnetic fields are structured in galaxies and within clusters of galaxies. This will allow us to look at the role played by magnetism in these regions.

这项研究旨在承担和回答有关宇宙及其历史的基本问题。同时我们将开发新的技术和仪器来帮助回答未来的问题。我们解决了天体物理学中的许多前沿问题。其中包括：宇宙是如何变成现在这个样子的？导致宇宙中最大结构发展的过程是什么？导致今天存在的星系和星系团的种子条件是什么？我们可以通过观察宇宙微波背景辐射（CMBR）来研究这些问题，这是“大爆炸”后不久发射的无线电波。我们工作的一部分是研究波，以寻找宇宙存在的最初几分之一秒内形成的结构印记。我们还可以通过寻找它们在 CMBR 上投射的“阴影”来找到最早形成的星系团。天文学的巨大进步来自于新技术的引入，我们希望继续引领干涉测量技术的应用。这种成像技术最初是在我们的射电天文学小组中开发的，但我们现在正在将其开发用于可见波长的天文学。这项工作将完成干涉仪的开发，该干涉仪将能够看到恒星和星系中心的细节，而这些细节是用其他方式无法看到的。我们还旨在通过开发技术使干涉望远镜能够在给定时间观测更多的天空，从而推进干涉测量在射电天文学中的应用。这在广泛的天文学研究中具有广泛的应用。我们的目标是通过使用能够在形成早期阶段看到大量恒星的仪器来回答有关恒星如何形成的基本问题。我们还计划使用未来几年上线的望远镜以前所未有的细节观察其他太阳系中恒星和行星的形成。通过使用最近开发的望远镜的数据，我们将开始研究星系和星系团内磁场的结构。这将使我们能够了解磁力在这些区域所发挥的作用。
