How fast is the Universe expanding? This project aims to produce the most precise measurement to date of the present day expansion rate of the Universe using gravitational waves and thus resolve current tensions plaguing existing measurements. We plan to develop the most comprehensive catalogue of gravitational waves and their hosts using the largest galaxy surveys in the world and use innovative statistical techniques to extract cosmological measurements from them. Expected outcomes include new knowledge of what the Universe is made of and how it has evolved, and enhanced international collaboration between Australia and other survey member countries. Anticipated benefits include new software and methods for the analysis of big data.

宇宙扩展的速度有多快？该项目旨在使用引力波生成宇宙当天膨胀率的最精确测量，从而解决困扰现有测量结果的当前紧张局势。我们计划使用世界上最大的星系调查开发最全面的引力波及其宿主目录，并使用创新的统计技术从中提取宇宙学测量。预期的结果包括有关宇宙的制造以及它如何发展的新知识，并增强了澳大利亚与其他调查成员国之间的国际合作。预期的好处包括新的软件和用于分析大数据的方法。
