A Space Odyssey: Exploring the Universe with Gravitational-Wave Sirens. 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 ex ....A Space Odyssey: Exploring the Universe with Gravitational-Wave Sirens. 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.Read moreRead less

Summary
Illuminating the dark universe. This project aims to measure and explain the dark side of the universe, by performing new theoretical analyses of two groundbreaking surveys. Dark energy and dark matter are amongst the most profound puzzles facing fundamental physics. The Dark Energy Survey expects to discover approximately 3000 supernovae, and using The Dark Energy Spectroscopic Instrument will measure distances to 30 million galaxies. This project will combine these findings to determine whethe ....Illuminating the dark universe. This project aims to measure and explain the dark side of the universe, by performing new theoretical analyses of two groundbreaking surveys. Dark energy and dark matter are amongst the most profound puzzles facing fundamental physics. The Dark Energy Survey expects to discover approximately 3000 supernovae, and using The Dark Energy Spectroscopic Instrument will measure distances to 30 million galaxies. This project will combine these findings to determine whether dark energy changes with time, narrow the search for a quantum theory of gravity, and complete the standard model of particle physics by measuring the mass of the neutrino, a subatomic particle. This will substantially advance our understanding of the physics of our Universe, inspiring the next generation of innovators.Read moreRead less
Gravity effects in quantum clocks and sensors: foundations and applications. Time is among the most precisely measurable quantities in physics, yet it is also the least understood concept in physics. This project aims to develop a mathematical framework describing measurements of time with high-precision clocks sensitive to both quantum and gravitational effects. The project expects to deliver new knowledge in the foundations of quantum physics by describing new gravitational effects in quantum ....Gravity effects in quantum clocks and sensors: foundations and applications. Time is among the most precisely measurable quantities in physics, yet it is also the least understood concept in physics. This project aims to develop a mathematical framework describing measurements of time with high-precision clocks sensitive to both quantum and gravitational effects. The project expects to deliver new knowledge in the foundations of quantum physics by describing new gravitational effects in quantum systems. Expected outcomes include enhanced understanding of time in quantum theory and strategies for harnessing gravitational effects in high-precision clocks, bringing cultural benefits to society and paving the way towards improved quantum technologies that are expected to bring economic benefits in the next two decades.
