Australia's scientific reputation is enhanced through participation in international collaborations that aim to solve long-standing mysteries in science. The Pierre Auger Observatory covers a huge 3000 square km in western Argentina, where we are attempting to solve one of the biggest puzzles in modern astrophysics - the origin of the highest energy cosmic rays, particles 100 million times more energetic than we can produce on Earth. Adelaide scientists were founding members of the Auger project, and now have leading roles within the experiment. This is providing our students with access to world-class facilities and researchers in a field which has moved to the mainstream of astrophysics research.Read moreRead less
Development and study of a new theory of gravity. Gravity is thought to be an understood physical phenomena. But recently dramatic discoveries have revealed that major aspects of this phenomenon have been completely missed. This research project will develop and explore implications of these discoveries. At one level this project is about major breakthroughs in fundamental science, but discoveries are revealing space to be a complex dynamic system, and new technologies to detect and exp ....Development and study of a new theory of gravity. Gravity is thought to be an understood physical phenomena. But recently dramatic discoveries have revealed that major aspects of this phenomenon have been completely missed. This research project will develop and explore implications of these discoveries. At one level this project is about major breakthroughs in fundamental science, but discoveries are revealing space to be a complex dynamic system, and new technologies to detect and exploit this are foreseen. There is some evidence that space is a self-organising information system of a totally new kind, and this will also have applications. At a scientific level these developments will attract considerable international attention and will enthuse younger researchersRead moreRead less

Dark gas and the formation of molecular clouds. Using frontline radio telescopes in Australia, Chile and Antarctica the project aims to understand how molecular clouds are formed in space, a part of the life cycle of our galaxy, and the role of hard-to-detect 'dark gas' in this process. Australia's Mopra telescope plays a central role in this international endeavour.
Energetic particle interactions in the universe: consequences for cosmic ray, gamma ray and neutrino astrophysics. The most energetic phenomena in the Universe will be explored with giant cosmic ray, neutrino and gamma ray telescopes. Particles accelerated or produced in astrophysical sources interact in their magnetic, matter and radiation environment, making cosmic rays, gamma rays and neutrinos. Subsequently, interactions in space as they travel to Earth change what we see. With theoretical w ....Energetic particle interactions in the universe: consequences for cosmic ray, gamma ray and neutrino astrophysics. The most energetic phenomena in the Universe will be explored with giant cosmic ray, neutrino and gamma ray telescopes. Particles accelerated or produced in astrophysical sources interact in their magnetic, matter and radiation environment, making cosmic rays, gamma rays and neutrinos. Subsequently, interactions in space as they travel to Earth change what we see. With theoretical work proposed in this project we aim to determine where in the Universe the highest energy cosmic rays originate, and the fundamental processes responsible for them. It will also lead to a greater understanding of how active galaxies and other astrophysical objects function.Read moreRead less
Astrophysics with the CANGAROO III Gamma-ray Telescope. This project will explore the last remaining part of the electromagnetic spectrum previously inaccessible in astronomy. It covers two decades of photon energy, above those accessible to satellite telescopes, and below those accessible to previous generations of ground-based VHE gamma-ray telescopes. Observations in those other energy ranges give us confidence that there is much to be discovered. We will provide an Australian contribution ....Astrophysics with the CANGAROO III Gamma-ray Telescope. This project will explore the last remaining part of the electromagnetic spectrum previously inaccessible in astronomy. It covers two decades of photon energy, above those accessible to satellite telescopes, and below those accessible to previous generations of ground-based VHE gamma-ray telescopes. Observations in those other energy ranges give us confidence that there is much to be discovered. We will provide an Australian contribution to the CANGAROO III telescope project, supporting the multi-million dollar contribution of our Japanese partners. Based at Woomera, this work maintains Australian access to a key astrophysical field at very modest cost.Read moreRead less

Studies of the Highest Energy Particles in Nature. One of the greatest mysteries of modern astrophysics is the origin of the highest energy cosmic rays. While rare, these subatomic particles possess enormous energies, some 100 million times larger than we can impart to a proton in man-made accelerators. Theory struggles to identify cosmic ray acceleration mechanisms, but these particles do exist. This project will fund our participation in the world's largest cosmic ray observatories, and ou ....Studies of the Highest Energy Particles in Nature.

Theory struggles to identify cosmic ray acceleration mechanisms, but these particles do exist. This project will fund our participation in the world's largest cosmic ray observatories, and our aim is to use the characteristics of the incoming particles (mass, energy and arrival directions) to determine the likely sources of the most energetic particles known in Nature.Read moreRead less

A major upgrade is under-way to enhance the sensitivity of the 3000 square kilometre Pierre Auger Observatory in its search for the origin of the highest energy cosmic rays, the most energetic particles known in the Universe. This follows an unexpected Auger result that indicates a significant fraction of these cosmic rays are heavy nuclei. This project, assisting the upgrade, is expected to significantly improve the observatory's ability to identify the mass, and hence the electric charge, of the incoming cosmic rays, allowing astrophysical source directions to be identified for the low charge particles less affected by cosmic magnetic fields. The project will also contribute to the understanding of particle interactions at energies well beyond those explored at the Large Hadron Collider.Read moreRead less
