A Space Odyssey: Exploring the Universe with Gravitational-Wave Sirens (2022-2025)

Abstract

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.
