Our research aims to investigate a range of high-priority science topics in these areas: i. studying high-energy and high-redshift explosive transients and how they relate to gravitational wave eventsii. investigating the growth and evolution of the first stars and black holes in galaxiesiii. determining the properties of accretion disks in active galactic nucleiiv. measuring the fundamental properties of white dwarf stars, the remnants of stars like the Sunv. investigating the properties of exoplanets, brown dwarfs and low mass starsvi. determining the evolution of tidal disruption events in galaxies where stars are torn apart as they come close to a supermassive black vii. investigating the origin of the stars seen in the centre of the Milky Way galaxy viii. determining the structure of the Milky Way galaxy ix. investigating the auroral emission of exoplanets x. developing the concept of an intensity interferometry system for the Cherenkov Telescope Array to provide high-resolution images of cosmic objectsWe will deliver this programme by carrying out observations using a broad range of ground and space based observing facilities, including XMM-Newton, HST, Swift, GAIA, JWST, ALMA, VLT, VISTA, WHT, INT, LT, NGTS, GOTO and Spitzer, and by conducting numerical simulations using major High Performance Computer facilities such as DiRAC.

我们的研究旨在研究这些领域的一系列高优先级科学主题：1 .研究高能和高红移爆炸瞬态及其与引力波事件的关系。研究星系中第一批恒星和黑洞的生长和演化。确定活动星系核中吸积盘的性质。测量白矮星的基本特性，白矮星是像太阳这样的恒星的残骸。研究系外行星、褐矮星和低质量恒星的特性。在星系中，恒星在接近超大质量的黑vii时被撕裂，确定潮汐破坏事件的演化。研究银河系中心的恒星的起源。决定了银河系的结构。为切伦科夫望远镜阵列开发强度干涉测量系统的概念，以提供宇宙物体的高分辨率图像。我们将通过使用广泛的地面和空间观测设施进行观测，包括xmm -牛顿、HST、Swift、GAIA、JWST、ALMA、VLT、VISTA、WHT、INT、LT、NGTS、GOTO和斯皮策，来实现这一计划。并利用主要的高性能计算机设施（如DiRAC）进行数值模拟。
