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

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. 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, t ....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. 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
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
