The origin of (dark) matter. This project aims to discover the origin and nature of dark matter and why the Universe contains more matter than antimatter – two important unresolved problems in particle physics and cosmology. These questions cannot be resolved within the framework of the particle physics Standard Model, and thus provide concrete evidence that new elementary particle physics remains to be uncovered.

This project aims to discover the origin and nature of dark matter and why the Universe contains more matter than antimatter – two important unresolved problems in particle physics and cosmology. These questions cannot be resolved within the framework of the particle physics Standard Model, and thus provide concrete evidence that new elementary particle physics remains to be uncovered. This project aims to explore the origin of dark matter, new mechanisms for creating a matter-antimatter asymmetry, and the possibility that dark and ordinary matter share a common origin. This project could address humanity's deep need to understand the nature of the universe and our origins.Read moreRead less
Frontiers in particle and astroparticle physics. This project will address fundamental questions about our universe, drawing on new experimental data at the cosmic and energy frontiers: what is the cosmological dark matter; why does the universe contain more matter than antimatter; what new surprises may be revealed? The answers will provide a guide to develop fundamental theories of nature.
New Tests of Fundamental Physics & Astrophysics with Atmospheric Neutrinos. Neutrinos are the least understood of the known fundamental particles, yet they hold the key to some of the most important open questions in physics and astrophysics. This project aims create new knowledge, which is needed now, using existing and imminent atmospheric neutrino data. It will pave the way to better understand the origin of the matter-antimatter asymmetry of the universe, supernovae, and dark matter.

Origins and implications of cosmic explosions . This project aims to solve the origin of Fast Radio Bursts (FRBs) by conducting a study of a large sample (>100) of localised bursts detected with a new coherent FRB detection system called CRACO deployed at the Australia Square Kilometre Array Pathfinder (ASKAP). Such a rich sample will enable novel studies of the structure of the Universe.

This project aims to solve the origin of Fast Radio Bursts (FRBs) by conducting a study of a large sample (>100) of localised bursts detected with a new coherent FRB detection system called CRACO deployed at the Australia Square Kilometre Array Pathfinder (ASKAP). Such a rich sample will enable novel studies of the structure of the Universe. The powerful and sensitive CRACO system will also search for transients that last for hundreds of milliseconds, exploring new types of astrophysical phenomena that give insight into the Universe's extremes. These discoveries will have a significant impact on science, establishing Australia as a key player in the international FRB community.

Transforming fast radio bursts into an astrophysical tool. This project aims to determine what causes fast radio bursts by utilising the revolutionary capabilities of the Australian Square Kilometre Array Pathfinder.

This project aims to determine what causes fast radio bursts by utilising the revolutionary capabilities of the Australian Square Kilometre Array Pathfinder. Fast radio bursts remain one of the most poorly understood astronomical objects; only the localisation of a large population will resolve the origin of their enigmatic emissions. This project will deliver a catalogue of localised fast radio bursts, pinpointed to host galaxies and an explanation for how and what produces the bursts. This will demonstrate the capabilities of novel Australian technology, and deliver benefit, underpinning a plan for surveys for next generation radio telescopes such as the Square Kilometre Array.Read moreRead less
AIM-GWM: Afterglow Imaging and Modelling of Gravitational-Wave Mergers. 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 insight ....AIM-GWM: Afterglow Imaging and Modelling of Gravitational-Wave Mergers. 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
Pinpointing the hosts of Fast Radio Bursts with UTMOST-2D. This project proposes to localise a sample of detected ‘fast radio bursts’ to their host galaxies (or local progenitors) for the first time. ‘Fast radio bursts’ are impulsive bursts of radio energy, with characteristics consistent with an origin billions of light-years from Earth. If the source of the bursts can be pinpointed, they would offer a unique tool to study the tenuous, otherwise nearly invisible plasma that permeates the interg ....Pinpointing the hosts of Fast Radio Bursts with UTMOST-2D. This project proposes to localise a sample of detected ‘fast radio bursts’ to their host galaxies (or local progenitors) for the first time. ‘Fast radio bursts’ are impulsive bursts of radio energy, with characteristics consistent with an origin billions of light-years from Earth. If the source of the bursts can be pinpointed, they would offer a unique tool to study the tenuous, otherwise nearly invisible plasma that permeates the intergalactic medium. They could also be used as cosmic rulers to measure the expansion history of the Universe. To date, no burst has been associated with a host galaxy at a known distance, and some researchers maintain that fast radio bursts originate from more nearby sources, potentially even within our own Galaxy. The project plans to explore this hypothesis.Read moreRead less

This project expects to localise 100s of bursts using novel infrastructure deployed on Australia's largest radio telescopes. Expected outcomes include an understanding of the processes that shape both the large-scale structures of the Universe, and the extreme conditions that exist at the sites of Fast Radio Bursts. This should provide significant benefits to our fundamental knowledge of the Universe, inspire students into careers in science, technology, engineering and mathematics, and develop signal processing techniques of application to both the Square Kilometre Array and industry.Read moreRead less

This project aims to investigate the origin of massive black holes observed in recent years by gravitational wave detectors. This project expects to generate new knowledge in the area of very massive stars utilising stellar evolution models, hydrodynamic simulations, light curve calculations and supernova observations, in order to explain the unexpected absence of a gap in the black hole mass distribution. Expected outcomes of this project include a better understanding of mass loss and the collapse of very massive stars as key factors for the observed black hole mass distribution.This should provide significant benefits for gravitational wave astronomy, but also for observations of stellar explosions by informing future survey strategies.
