项目摘要

The Universe is a state of continuous evolution. This started with the Big Bang, and the small irregularities which later grew into clusters, galaxies, and stars. Large black holes formed at the centre of the galaxies. Infall of gas into the central black holes leads to highly energetic jets. Stars interact with their surroundings through winds, and for massive stars, through explosions at the end of their lives. The ejecta enrich the galaxies with new elements, molecules and dust. The Jodrell Bank Centre for Astrophysics studies the various phases of evolution especially through radio emission. Radio emission traces ionized plasmas which are found in high energy environments, The irregularities of the Big Bang are studied through the cosmic microwave radio emission. Galaxies emit radio emission and these are used to trace their evolution, from formation to star bursts. The cores of massive stars, left after their supernova explosions, emit radio pulses. The radio emissions are detected using a variety of telescopes. The Planck Space Telescope observes the cosmic microwave background. The Lovell Telescope detects the emission from pulsars. The e-Merlin array resolves the emission from individual galaxies. The research is supported by an active technology program. We develop cyogenically cooled amplifiers, and low noise detectors at high and low frequencies, both for space telescopes and ground-based. Much of our research is based on wide area surveys. In addition to radio surveys, we also make use of high resolution optical surveys. Gravity is an important focus for our research. The bending of light and radio waves can be used to detect material otherwise invisible. We use this to detect planets in the outer regions of the stellar systems. Gravitational waves can be detected through the long-term monitoring of pulsars. The research in this grant covers cosmology, from the origin of large-scale structure in the Universe to the formation of cluster of galaxies, Pulsars, both as objects in their own right and as tracers of gravity, Dust and molecules in the interstellar medium, and finally a vigorous program of development of radio technology.The future of radio astronomy is the Square Kilometre Array (SKA), in which the UK has a leading role. The research of the Jodrell Bank Centre for Astrophysics is directed towards the SKA. Over the next three years, we will continue our study of the radio Universe at all scales. The SKA will bring this to fruition, and provide a unique tracer of the continuing evolution of the Universe.

宇宙是一个不断演化的状态。这始于大爆炸，以及后来成长为星团，星系和恒星的小不规则性。巨大的黑洞在星系中心形成。进入中心黑洞的气体会导致高能喷流。恒星通过风与周围环境相互作用，对于大质量恒星，通过生命末期的爆炸。喷出物用新元素、分子和尘埃丰富了星系。Jodrell Bank天体物理学中心研究演化的各个阶段，特别是通过无线电发射。射电辐射追踪高能环境中的电离等离子体，通过宇宙微波射电辐射研究大爆炸的不规则性。星系发出无线电辐射，这些辐射被用来追踪它们的演化，从形成到星星爆发。大质量恒星的核心，在超新星爆炸后留下，发出无线电脉冲。无线电辐射是用各种望远镜探测到的。普朗克太空望远镜观测宇宙微波背景辐射。洛弗尔望远镜探测到了恒星的辐射。e-Merlin阵列可以分辨来自单个星系的辐射。这项研究得到了一项积极的技术计划的支持。我们开发低温冷却放大器，并在高和低频率的低噪声探测器，无论是空间望远镜和地面。我们的大部分研究都是基于大范围的调查。除了无线电勘测，我们还利用高分辨率光学勘测。重力是我们研究的一个重要焦点。光和无线电波的弯曲可以用来探测其他不可见的物质。我们用它来探测恒星系统外部区域的行星。引力波可以通过对恒星的长期监测来探测。该基金的研究范围包括宇宙学，从宇宙大尺度结构的起源到星系团的形成，脉冲星，作为天体本身和引力的示踪剂，星际介质中的尘埃和分子，最后是射电天文学发展的有力计划。射电天文学的未来是平方公里阵列（SKA），其中英国发挥了主导作用。Jodrell Bank天体物理中心的研究是针对SKA的。在接下来的三年里，我们将继续在所有尺度上研究无线电宇宙。SKA将实现这一目标，并提供一个独特的宇宙持续演化的示踪剂。
