General relativistic light propagation effects: new insight into cosmic voids, dark matter, dark energy, and Einstein's theory of gravity. This project aims to be the first to develop new methods which will allow accurate study of light propagation effects. These methods remove the “noise” (light propagation effects) from observational data, resulting in unprecedented accuracy of the analyses and new insight into properties of dark energy.

This project aims to be the first to develop new methods which will allow accurate study of light propagation effects. These methods remove the “noise” (light propagation effects) from observational data, resulting in unprecedented accuracy of the analyses and new insight into properties of dark energy. At the same time these methods use the “noise” as the actual signal to measure properties of the Universe, especially the mass distribution inside cosmic voids (places in the Universe avoided by galaxies), which will solve the problem of dark matter distribution inside cosmic voids. The project aims to use light propagation effects to test Einstein's theory of gravity at cosmological scales.Read moreRead less
Explorations in the Foundations of Quantum Gravity. Despite almost a century of struggle, gravitation (as described by Einstein's general theory of relativity) remains divided from the principles of quantum theory (the framework in which our best theories of particle physics are couched). Bringing them together constitutes one of the most urgent problems of physics.

Despite almost a century of struggle, gravitation (as described by Einstein's general theory of relativity) remains divided from the principles of quantum theory (the framework in which our best theories of particle physics are couched). Bringing them together constitutes one of the most urgent problems of physics. By exploring the foundations of the problem, and the various proposed resolutions, from both historical and philosophical perspectives, this project aims both to shed new light on why it so stubbornly resists a solution and to assist in its solution. It will map out the specific features of the various approaches to quantum gravity with a view to offering researchers a helpful tool to navigate and compare their virtues and vices.Read moreRead less
Bulk-boundary correspondence in quantum many-body systems. This project will develop theoretical and numerical methods to explore how the bulk properties of quantum materials at low temperature are manifested on the edge of the material. Characterising this bulk-boundary correspondence will uncover new regimes of physics and underpin the development of powerful quantum technologies in the laboratory.

Summary
Discovering the most extreme pulsars with the next generation radio surveys. Finding radio pulsars has always been an extremely rewarding challenge and has led to Nobel Prize winning science. We are now entering a new era of radio astronomy and have new game changers, sensitive, wide-field-of-view imaging telescopes and massive compute resources, to search for extreme pulsars. Such pulsars, including pulsar-blackhole systems and sub-millisecond pulsars, cannot be found with traditional pulsar su ....Discovering the most extreme pulsars with the next generation radio surveys. Finding radio pulsars has always been an extremely rewarding challenge and has led to Nobel Prize winning science. We are now entering a new era of radio astronomy and have new game changers, sensitive, wide-field-of-view imaging telescopes and massive compute resources, to search for extreme pulsars. Such pulsars, including pulsar-blackhole systems and sub-millisecond pulsars, cannot be found with traditional pulsar surveys, but provide us unique laboratories to test gravity theories at ultra-strong gravitational fields and probe the state of matter at supra-nuclear densities. In this project I will leverage the Australian Square Kilometre Array Pathfinder (ASKAP) to discover the most extreme pulsars in deep all-sky continuum surveys.Read moreRead less
Radio follow-up of gravitational wave events. This project aims to use three Australian radio telescopes to search for and monitor radio waves from future gravitational wave events.

This project aims to use three Australian radio telescopes to search for and monitor radio waves from future gravitational wave events. The detection of gravitational waves and electromagnetic radiation from a neutron star merger was a scientific breakthrough, with important implications for physics and astronomy. The observations from this project will provide key information to reveal what causes some of the most energetic events in the Universe, their environment and how they evolve. The outcomes of this project include increased international collaboration with this global effort, and new techniques for automatic data processing and analysis, as well as engaging future students as we build Australian expertise in a new area of research.Read moreRead less

The development of more generic and efficient Bayesian statistical methods will not only benefit applied statisticians but also the more occasional users of statistics in other disciplinary areas. The success of this project will enhance Australia's reputation as a strong contributor to the development of Bayesian methodologies. Two PhD students will also be provided training in computational Bayesian statistics.Read moreRead less
Do black holes exist? This project aims to verify if black holes can actually exist in our Universe. It is still unknown if any of the candidate objects possess the key black hole feature -- a trapped region from which no signal can escape. By focusing on conditions for existence of trapped regions, this project expects to describe their neighborhoods and observable properties. This information is critical for interpretation of the data from the next generation of gravitational wave detectors an ....Do black holes exist? This project aims to verify if black holes can actually exist in our Universe. It is still unknown if any of the candidate objects possess the key black hole feature -- a trapped region from which no signal can escape. By focusing on conditions for existence of trapped regions, this project expects to describe their neighborhoods and observable properties. This information is critical for interpretation of the data from the next generation of gravitational wave detectors and radio telescopes, and for determining the true nature of astrophysical black hole candidates. Further benefits include simplification of calculations of the observable properties of compact objects and resolution of a long-standing black hole information loss paradox.Read moreRead less

This project aims to use methods from mathematical scattering theory to resolve problems in the spectral analysis and index theory of differential operators. Both areas underpin the theoretical understanding of physical materials at micro length scales where quantum phenomena dominate. The project will develop new mathematical results in spectral analysis and geometry, and apply its results to theoretical models of quantum phenomena whose spectral properties are at the limit of the range of mathematical techniques. Solving these problems is expected to influence non-commutative analysis.Read moreRead less
