A Transdimensional Approach to Gravitational-Wave Astronomy. This project uses ripples in the fabric of spacetime––gravitational waves––to understand the cosmos and the fundamental nature of reality. We aim to discover new sources of gravitational waves from exploding stars. Using gravitational waves from colliding black holes, we aim to uncover new physics beyond Einstein's theory of general relativity. To achieve these goals we will develop tools from the cutting-edge of data science.
Precision cosmic expansion in the era of gravitational-wave astronomy. The disagreement in the size of the cosmic expansion rate, between measurements from local galaxy indicators and predictions from the early Universe, is a crisis for cosmology. This Project aims to resolve this situation using recent scientific breakthroughs in both observations and theory. We will optimise expansion measurements from the standard sirens discovered by gravitational-wave astronomy by accurate modelling of th ....Precision cosmic expansion in the era of gravitational-wave astronomy. The disagreement in the size of the cosmic expansion rate, between measurements from local galaxy indicators and predictions from the early Universe, is a crisis for cosmology. This Project aims to resolve this situation using recent scientific breakthroughs in both observations and theory. We will optimise expansion measurements from the standard sirens discovered by gravitational-wave astronomy by accurate modelling of the cosmic velocity field which limits this analysis. And we will use recent breakthoughs in numerical general relativity to explore the influence of space-time curvature variations on these measurements. We will hence improve our understanding of the most important parameter describing the Universe, and its physics.Read moreRead less
Weighing the Universe using fast radio bursts. Fast radio bursts are a newly-discovered astronomical phenomenon whose millisecond-timescale emission occurs at cosmological distances, rendering them exceptional probes of the matter that lies in intergalactic space. This project aims to measure the positions and obtain the distances to these bursts to make a direct measurement of the density of ordinary matter in the Universe, at least 50 per cent of which is believed to remain undetected in inter ....Weighing the Universe using fast radio bursts. Fast radio bursts are a newly-discovered astronomical phenomenon whose millisecond-timescale emission occurs at cosmological distances, rendering them exceptional probes of the matter that lies in intergalactic space. This project aims to measure the positions and obtain the distances to these bursts to make a direct measurement of the density of ordinary matter in the Universe, at least 50 per cent of which is believed to remain undetected in intergalactic space. This project will measure the distribution of this missing matter, and find how it has evolved throughout the history of the Universe. This will provide significant benefits, such as addressing two fundamental questions about our Universe: how much matter does it contain, and has a large fraction of it hitherto evaded detection in intergalactic space?Read moreRead less
Domestic violence disclosure schemes: A national review. In 2014 family violence was declared a national emergency in Australia. In the years since there has been extensive law reform activity. Domestic violence disclosure schemes have emerged within this context as a policy option that may improve safety outcomes for victims. However, there is currently no evidence as to the impact of these schemes and no consultation with victims as to their value. This project aims to generate the evidence re ....Domestic violence disclosure schemes: A national review. In 2014 family violence was declared a national emergency in Australia. In the years since there has been extensive law reform activity. Domestic violence disclosure schemes have emerged within this context as a policy option that may improve safety outcomes for victims. However, there is currently no evidence as to the impact of these schemes and no consultation with victims as to their value. This project aims to generate the evidence required to inform decisions about the introduction of these schemes, to better understand what victim/survivors want from them, and how such schemes can be effectively operationalised. The findings seek to be relevant to all Australian states and territories as well as international jurisdictions.Read moreRead less

This project aims to capitalise on the dawn of the era of gravitational wave astronomy by studying the radio afterglows that result from gravitational wave merger events in minute detail. By comparing ultra-high resolution images to sophisticated computational models, we anticipate recovering information about the merger events that cannot be obtained from the gravitational wave data alone. In doing so, we expect new insights into not just of the extreme and unique physics in the aftermath of a violent neutron star merger, but also about the fundamental nature of the Universe, namely the speed at which it is expanding. This knowledge will provide significant benefits to astronomers studying the Universe at all wavelengths.Read moreRead less
