Hertfordshire Astronomy 2021-24

天体物理研究中心开展了从X射线到无线电波长范围的观测计划--通过计算机建模和模拟来支持这一计划。我们的研究范围从对宇宙中最遥远和最极端的星系的观测，到对试图探测太阳系外行星的观测的新颖的统计分析。在这两个极端之间，我们试图了解棕矮星和年轻恒星的性质，我们对银河系和附近星系进行射电测量，我们正在率先对北方射电天空和射电测量将发现的大量星系的红移进行广域测量。我们的研究利用了欧洲和国际所有主要天文观测站的观测资料，包括光学、射电和亚毫米波长的地面观测站，以及波长从远红外到X射线的空间观测站。计算机模拟让我们更好地了解在我们的观测中检测到的物理过程，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。

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.
