This project aims to reveal the highest energy cosmic-ray particles in our galaxy, produced in extreme and still unknown astrophysical processes. Their interaction with nuclei in space produces the highest energy gamma ray light. Our project will make use of this extreme gamma ray light with upgraded and next-generation gamma-ray telescope arrays. With accompanying data from Australian radio telescopes, and computer models of the cosmic ray interactions, our project can finally determine from where these cosmic rays originate, yielding insight into our galaxy's evolution. Complex machine learning methods will be needed in a project that provides a world-leading student training ground, motivated by a century old mystery in astronomy.Read moreRead less
The Carina Nebula: a massive star factory and the anchor for calibrating extragalactic star formation. Massive stars are vital to the life cycle of a galaxy, providing material and controlling the environment where new stars are made. This project will use the Australia Telescope to map the spectacular Carina Nebula, a hotbed of massive stars, to provide a picture of its stars and gas and a template for understanding star formation in distant galaxies.
Supernovae as the origin of antimatter in our galaxy. This project aims to uncover the origin of the bulk of the antimatter in our Milky Way Galaxy. Astrophysicists have known for forty years that our Galaxy glows with gamma-rays emitted by the annihilation of huge numbers of positrons, the antimatter partners to electrons. Certain supernovae are the likely source of these positrons. To fully investigate this idea and its ramifications, this project will perform three-dimensional supercomputer s ....Supernovae as the origin of antimatter in our galaxy. This project aims to uncover the origin of the bulk of the antimatter in our Milky Way Galaxy. Astrophysicists have known for forty years that our Galaxy glows with gamma-rays emitted by the annihilation of huge numbers of positrons, the antimatter partners to electrons. Certain supernovae are the likely source of these positrons. To fully investigate this idea and its ramifications, this project will perform three-dimensional supercomputer simulations of thermonuclear supernova explosions. This project aspires to resolve a long-standing mystery in astrophysics and provide an exemplar for best usage of Australian investment in astronomy and supercomputing infrastructure.Read moreRead less

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

This project aims to establish the use of millisecond-duration Fast Radio Bursts as a wholly new means to map out the distribution of matter in the Universe. 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
Electrodynamics of magnetic explosions in astrophysics. The project aims to develop a new model for solar flares and pulsars that more realistically describes these phenomena. Solar flares and pulsars involve strong magnetic fields changing rapidly as a function of time, implying enormous inductive potentials. The project aims to show how the inductive field and the plasma response to it can be included in an electrodynamic theory. It plans to apply this theory to solar flares, and show how it c ....Electrodynamics of magnetic explosions in astrophysics. The project aims to develop a new model for solar flares and pulsars that more realistically describes these phenomena. Solar flares and pulsars involve strong magnetic fields changing rapidly as a function of time, implying enormous inductive potentials. The project aims to show how the inductive field and the plasma response to it can be included in an electrodynamic theory. It plans to apply this theory to solar flares, and show how it can resolve the long-standing ‘number problem’. It also plans to apply the model to pulsars, and show how the long-standing dichotomy between the vacuum-dipole and rotating-magnetosphere models can be resolved by synthesising them. The project intends to combine these ideas into a new model for the most extreme examples of magnetic explosions: superflares and giant bursts on magnetars.Read moreRead less
Magnetic skeletons, solar flares, and space weather. This project aims to investigate how magnetic reconnection occurs during solar flares through accurate reconstruction of coronal magnetic fields from solar data before and after flares, and by reliable determination of field skeletons. Solar flares are dynamic events in the Sun's corona which cause local space weather storms. Magnetic reconnection is the accepted mechanism for flares but conventional models neglect the three-dimensional (3D) n ....Magnetic skeletons, solar flares, and space weather. This project aims to investigate how magnetic reconnection occurs during solar flares through accurate reconstruction of coronal magnetic fields from solar data before and after flares, and by reliable determination of field skeletons. Solar flares are dynamic events in the Sun's corona which cause local space weather storms. Magnetic reconnection is the accepted mechanism for flares but conventional models neglect the three-dimensional (3D) nature of the process. The project will improve 3D reconnection models for flares, and advance the ability to predict large events and hence space weather storms.Read moreRead less

This project intends to provide a next-generation fast radio burst detector for the Australian Square Kilometre Array Pathfinder. The project expects to both transform our understanding of fast radio bursts, enigmatic flashes of radio waves of unknown origin, but also use the bursts as tools to study the cosmic web of matter that resides in intergalactic space. To do so, the project aims to deliver a more sensitive detection system capable of localising a large sample of fast radio bursts to greater distances, found commensal to other observations. This should provide significant benefit, including the resolutions to key open astrophysical questions and improved scientific outcomes for transient searches with the Square Kilometre Array.Read moreRead less

Summary
The Nanten2 sub-millimetre telescope. The millimetre-wavelength sky holds the key for understanding how stars form in the coldest regions of interstellar space: the molecular clouds of our Galaxy. A new frontline facility in Chile will be used in an international research endeavour to map their structures, in order to find out how they form and what causes stars to be born inside them.
