This project aims to use the most powerful radio and optical telescopes in the world to identify the mechanisms driving the quenching of star formation in the most massive structures in the Universe. This research expects to answer some of the fundamental questions identified by the international astronomy community regarding how galaxies form and evolve, how star formation proceeds and why nearly half of the galaxies in the local Universe have stopped forming stars. It will forge strong links with international partners, strengthen Australian expertise in a critical area of astronomical research, offer an ideal platform for accelerating the training of students in STEM and contribute to public outreach work.

该项目旨在使用世界上最强大的射电和光学望远镜来确定宇宙中最大质量结构中恒星形成猝灭的机制。这项研究有望回答国际天文学界确定的一些基本问题，这些问题包括星系是如何形成和演化的，恒星形成是如何进行的，以及为什么本宇宙中近一半的星系已经停止形成恒星。它将与国际伙伴建立强有力的联系，加强澳大利亚在天文研究关键领域的专业知识，为加快STEM学生的培训提供理想的平台，并为公共宣传工作做出贡献。
