项目摘要

The Low Frequency Array (LOFAR) is a new-generation radio telescope operating at low radio frequencies, between about 30 and 240 MHz. With a sensitivity more than 100 times better than any previous telescope at these frequencies, high precision imaging capabilities, and an enormous field of view, LOFAR is by far the most powerful 100 MHz telescope on the planet. It is revolutionising our view of the low-frequency radio Universe.LOFAR has an extremely broad and diverse science case, ranging from cosmological studies of the nature of the early Universe to understanding the physics of our own Sun and the impact of Solar activity on the Earth's environment. It is carrying out detailed studies of the formation and lifecycles of galaxies, and of the supermassive black holes within them that can reach a billion times the mass of our own Sun. It is allowing the study of the laws of physics in some of the most extreme astrophysical environments. With its wide range of capabilities, it attracts a very broad user community and has impact on many of STFC's strategic priorities.LOFAR is an inherently international project. The core of the LOFAR array is located in the Netherlands, but receiver stations are spread around 8 partner countries in Europe, including the UK station at Chilbolton Observatory. The international stations greatly improve the imaging precision, and hence the scientific capability of the array.This grant is concerned with retaining the UK's leading involvement in LOFAR for the next three years, through annual subscription fees, and the operation, maintenance and data transport for the UK LOFAR station. It will also support UK involvement in an on-going upgrade to LOFAR, known as LOFAR2.0, which will greatly increase the capabilities of the array at lower frequencies, and open up a wealth of new science goals.

低频阵列(LOFAR)是新一代射电望远镜，工作在大约30至240兆赫的低频。LOFAR在这些频率下的灵敏度是以前任何望远镜的100多倍，高精度成像能力和巨大的视场，LOFAR是迄今为止地球上最强大的100 MHz望远镜。它正在彻底改变我们对低频无线电宇宙的看法。LOFAR有一个极其广泛和多样化的科学案例，从早期宇宙的宇宙学研究到理解我们自己的太阳的物理和太阳活动对地球环境的影响。它正在对星系的形成和生命周期进行详细的研究，以及其中的超大质量黑洞，这些黑洞的质量可以达到我们太阳的10亿倍。它使得在一些最极端的天体物理环境中研究物理定律成为可能。凭借其广泛的能力，它吸引了非常广泛的用户社区，并对STFC的许多战略优先事项产生了影响。LOFAR本质上是一个国际项目。LOFAR阵列的核心位于荷兰，但接收站分布在欧洲的8个伙伴国家，包括奇尔博顿天文台的英国站。国际空间站极大地提高了成像精度，从而提高了阵列的科学能力。这笔赠款涉及通过每年的订阅费以及英国LOFAR站的运营、维护和数据传输，在未来三年内保持英国在LOFAR方面的领先地位。它还将支持英国参与正在进行的LOFAR升级，即LOFAR2.0，这将极大地提高阵列在较低频率的能力，并开启一系列新的科学目标。
