The Centre for Astrophysics Research carries out observational programmes spanning the wavelength range from X-ray to radio -- supporting this by computer modelling and simulation. Our research ranges from observations of the most distant and extreme galaxies in the universe through to novel statistical analyses of observations seeking to detect planets outside our Solar System. In between these extremes, we seek to understand the properties of brown dwarfs and young stars, we carry out radio surveys of the Milky Way and of nearby galaxies, and we are pioneering wide-area surveys both of the northern radio sky and of the redshifts of the vast number of galaxies that the radio surveys will discover. Our research makes use of observations from all of the main European and international astronomical observatories, including ground-based observatories at optical, radio and submillimetre wavelengths, and space observatories at wavelengths ranging from the far infrared to X-rays. Computer simulations gives us a better understanding of the physical processes detected in our observations, and we need to apply advanced data-mining techniques to work with the very large datasets we are generating.

天体物理学研究中心执行的观测方案涵盖从X射线到无线电的波长范围，并通过计算机建模和模拟予以支持。我们的研究范围从宇宙中最遥远和最极端的星系的观测到对观测的新统计分析，以探测太阳系外的行星。在这两个极端之间，我们试图了解褐矮星和年轻恒星的性质，我们对银河系和附近的星系进行无线电调查，我们正在率先对北方无线电天空和无线电调查将发现的大量星系的红移进行广域调查。我们的研究利用了欧洲和国际所有主要天文观测台的观测结果，包括光学、无线电和亚毫米波长的地面观测台，以及从远红外到X射线波长的空间观测台。计算机模拟使我们能够更好地了解观察中检测到的物理过程，并且我们需要应用先进的数据挖掘技术来处理我们正在生成的非常大的数据集。
