Our research aims to investigate a range of high-priority science topics in these areas: i. studying high-energy and high-redshift transients and the relation of transients to gravitational wave eventsii. investigating the growth and evolution of the first stars and black holes in galaxiesiii. determining the properties of powerful active galactic nuclei including the Broad Line Regioniv. measuring the fundamental properties of white dwarf starsv. investigating the properties of exoplanets, brown dwarfs and low mass starsvi. investigating accretion processesvii exploring the formation of planetsWe 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, WHT, INT, LT, NGTS, GOTO and SAAO, and by conducting numerical simulations using major High Performance Computer facilities such as DiRAC.

我们的研究旨在调查以下领域的一系列高度优先的科学主题：研究高能和高红移瞬变以及瞬变与引力波事件的关系ii。研究星系中第一批恒星和黑洞的生长和演化iii。确定包括宽线区域在内的强大活动星系核的特性。测量白矮星的基本特性v。研究系外行星、褐矮星和低质量恒星的特性vi。研究吸积过程vii 探索行星的形成我们将通过使用广泛的地面和太空观测设施进行观测来实施该计划，包括 XMM-Newton、HST、Swift、GAIA、JWST、ALMA、VLT、WHT、INT、LT 、NGTS、GOTO 和 SAAO，并使用 DiRAC 等主要高性能计算机设施进行数值模拟。
