The Universe is in a state of continuous evolution. The Big Bang left small irregularities which later grew into clusters, galaxies, and stars. Large black holes formed at the centre of the galaxies. Stars and black holesinteract with their environment, heating the gas through jets and supernova explosions, and enriching the galaxies with new elements formed in stars, and with 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 from jets emitted by the black holes, and from gas ionized by massive stars. The cores of massive stars, left after their supernova explosions, emit radio pulses as so-called pulsars. All these 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. Jodrell Bank is active in each of these areas. The research is supported by an active technology program. We develop cryogenically 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, star formation, winds from the Sun, stars and extrasolar planets. It is supported by 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.

宇宙处于不断进化的状态。大爆炸留下了小的不规则性，后来成长为星系团，星系和恒星。巨大的黑洞在星系中心形成。恒星和黑洞与它们的环境相互作用，通过喷流和超新星爆炸加热气体，并用恒星中形成的新元素、分子和尘埃丰富星系。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。银河系从黑洞喷出的喷流和被大质量恒星电离的气体中发出无线电辐射。大质量恒星的核心，在超新星爆炸后留下的，发射出无线电脉冲，即所谓的射电星。所有这些无线电辐射都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。Jodrell Bank在这些领域都很活跃。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。这项资助的研究涵盖宇宙学，从宇宙大尺度结构的起源到星系团的形成，脉冲星，作为物体本身和引力的示踪剂，星星的形成，来自太阳的风，恒星和太阳系外行星。射电天文学的未来是平方公里阵列（SKA），英国在其中发挥着主导作用。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。
