This project aims to understand the unexplored population of non-active or quiescent supermassive black holes (SMBHs) using tidal disruption events - the multi-wavelength outburst resulting from a star being ripped apart by the tidal forces of the SMBH. This project will increase our understanding of the transient and accretion properties of SMBHs in a broad range of galaxies, while the expected outcomes include novel techniques for distinguishing different types of extreme SMBH emission and characterisation of the environments where these extreme transient events occur. These outcomes will facilitate the identification of transient SMBH events and enhance the scientific return of the next generation of international optical surveys.

该项目旨在利用潮汐破坏事件（恒星被SMBH的潮汐力撕裂而产生的多波长爆发）来了解未探索的非活跃或静止超大质量黑洞（SMBH）群体。该项目将增进我们对广泛星系中SMBH瞬态和吸积特性的理解，而预期成果包括用于区分不同类型的极端SMBH发射和描述这些极端瞬态事件发生的环境的新技术。这些结果将有助于识别瞬态SMBH事件，并提高下一代国际光学调查的科学回报。
