Astronomy can capture the public imagination to a greater extent than almost any other branch of science. It is accessible to anyone who gazes up into the night sky to look at the Moon, the planets, stars, and nearby galaxies. Our understanding of the universe has developed rapidly over the past several decades. On the basis of the standard cosmological model we live in a universe where at least two thirds of the mass energy is in the form of dark energy which causes the Universe to expand at an ever increasing rate. About a quarter of the mass energy is in the form of dark matter, most probably a new weakly interacting elementary particle yet to be detected on Earth (and hence of great interest to particle physicists). The remaining five percent of the mass energy is in the form of ordinary, or baryonic, matter of which only about a tenth is in stars and planets such as the Earth, and the rest resides mostly as gas in between galaxies.Our programme combines cutting-edge theoretical and observational research with innovative instrumentation development to understand the universe in which we inhabit. We blend theoretical research on the earliest phases of the Universe with theoretical and observational projects to determine the formation and evolution of black holes, galaxies, and the larger-scale structures in which they reside. We confront the predictions from our models with our latest observational results, while actively exploiting innovative instrumentation developments pursued in Durham. We will explore astrophysical clues to the identity of the dark matter and the nature of the dark energy, focus on the evolution of galaxies back to the earliest times in the Universe and the influence on which the larger-scale environment has had on their properties. We will investigate the formation and evolution of black holes and their role in determining the structure and properties of galaxies and their larger scale structures, using the latest instruments on ground-based observatories and Earth-orbiting satellites.

天文学比几乎任何其他科学分支更能激发公众的想象力。任何仰望夜空观察月球、行星、恒星和附近星系的人都可以使用它。在过去的几十年里，我们对宇宙的认识迅速发展。根据标准宇宙学模型，我们生活在一个宇宙中，至少三分之二的质量能量以暗能量的形式存在，这导致宇宙以不断增加的速度膨胀。大约四分之一的质量能量是以暗物质的形式存在的，暗物质很可能是一种尚未在地球上检测到的新的弱相互作用基本粒子（因此引起了粒子物理学家的极大兴趣）。剩余百分之五的质量能量以普通或重子的形式存在，其中只有大约十分之一存在于恒星和行星（例如地球）中，其余的大部分以气体形式存在于星系之间。我们的计划结合了切割- 通过创新仪器开发进行前沿理论和观测研究，以了解我们所居住的宇宙。我们将对宇宙最早阶段的理论研究与理论和观测项目相结合，以确定黑洞、星系及其所在的更大规模结构的形成和演化。我们将模型的预测与最新的观测结果进行比较，同时积极利用达勒姆所追求的创新仪器开发。我们将探索暗物质身份和暗能量本质的天体物理学线索，重点关注宇宙最早时期的星系演化以及更大尺度的环境对其性质的影响。我们将利用地面天文台和地球轨道卫星上的最新仪器，研究黑洞的形成和演化及其在确定星系及其更大规模结构的结构和特性中的作用。
