Caught in the act by PAndAS: An unparalleled view of galaxy evolution. How do galaxies, like our own Milky Way, form? Using a new survey of the nearby cosmos, we will search for the signatures of galactic cannibalism, the disrupted bodies of smaller galaxies, and use this archaeology to piece together the formation history. We will also reveal the presence of local dark matter, whose action has shaped our own galaxy's formation.
Converging on new particles and fundamental symmetries. The goal of this project is to test theories for new particles and fundamental symmetries. By using advanced computational and statistical methods to combine all relevant data from many different experiments with a large number of different theoretical predictions, it expects to reveal just how well different theories actually describe reality. This will help us to understand what new particles and fundamental symmetries exist beyond thos ....Converging on new particles and fundamental symmetries. The goal of this project is to test theories for new particles and fundamental symmetries. By using advanced computational and statistical methods to combine all relevant data from many different experiments with a large number of different theoretical predictions, it expects to reveal just how well different theories actually describe reality. This will help us to understand what new particles and fundamental symmetries exist beyond those we already know. It will lead to new algorithms and computational methods in machine learning and statistical sampling, and will train a cohort of graduates highly skilled in statistical data science and research computing.Read moreRead less
Unveiling the first billion years: enabling epoch of reionisation science. This project aims to deliver detections and exploration of the Epoch of Reionisation (EoR) through observation of the 21 cm hydrogen emission line from gas in the first billion years of the Universe. The EoR and Cosmic Dawn mark the two remaining unobserved periods in the history of the Universe. Together, they are witness to the formation, birth and illumination of the first stars, galaxies and x-ray sources, and the con ....Unveiling the first billion years: enabling epoch of reionisation science. This project aims to deliver detections and exploration of the Epoch of Reionisation (EoR) through observation of the 21 cm hydrogen emission line from gas in the first billion years of the Universe. The EoR and Cosmic Dawn mark the two remaining unobserved periods in the history of the Universe. Together, they are witness to the formation, birth and illumination of the first stars, galaxies and x-ray sources, and the consequent transformation of the intergalactic medium from a cold, neutral fog of hydrogen, to a heated, ionised canvas for the luminous Universe. The 21cm neutral hydrogen radio signal maps the astrophysics and cosmology of the first billion years, providing a direct tracer of their evolution and spatial distribution. The project will deliver advances in early Universe physics by circumventing limitations of current experiments, and will deliver lasting scientific and technological breakthroughs.Read moreRead less
The radio transient sky in real time. This project plans to use three new Australian telescopes to conduct the most comprehensive search ever made for transient sources. Transient phenomena (astronomical objects that appear and disappear or change rapidly) are laboratories for exploring some of the most extreme processes in the Universe. Radio astronomy is on the verge of a revolution in the study of transients, made possible by new technology. The project aims to leverage the learnings from the ....The radio transient sky in real time. This project plans to use three new Australian telescopes to conduct the most comprehensive search ever made for transient sources. Transient phenomena (astronomical objects that appear and disappear or change rapidly) are laboratories for exploring some of the most extreme processes in the Universe. Radio astronomy is on the verge of a revolution in the study of transients, made possible by new technology. The project aims to leverage the learnings from the new technology by developing intelligent algorithms able to extract weak signals from massive datasets to find rare and exotic objects ranging from extra-solar planets to gamma-ray bursts, exploring the unknown in ways that have previously not been possible. These algorithms may have broad impact in astronomy.Read moreRead less
A networked robotic telescope array for coincident detection of transient phenomena in the optical, gravitational wave, neutrino and radio spectra. An international collaboration of scientists will employ a global network of rapid response robotic telescopes and detectors to study exotic transient phenomena in the early Universe. Potential spin-offs include the application of novel image analysis techniques for identifying and tracking dangerous space junk.
In Search of New Gravity: testing advanced theories of gravity with cosmological data. The most startling discovery in cosmology in the last few decades has been that the Universe is accelerating. This remarkable fact indicates that our theory of gravity may need revision. Our current theory, Einstein’s theory of General Relativity, stands up in our solar system. If this theory breaks down on large scales, leading to the accelerating expansion, there must be some ‘cross-over’ scale where the the ....In Search of New Gravity: testing advanced theories of gravity with cosmological data. The most startling discovery in cosmology in the last few decades has been that the Universe is accelerating. This remarkable fact indicates that our theory of gravity may need revision. Our current theory, Einstein’s theory of General Relativity, stands up in our solar system. If this theory breaks down on large scales, leading to the accelerating expansion, there must be some ‘cross-over’ scale where the theory changes. This project will make theoretical predictions for those models that contain a cross-over and test them against current data for current and upcoming Australian cosmological surveys. It will determine if our current theory of gravity is a satisfactory theory, and if it is not, which new theory should replace it.Read moreRead less
Growing galaxies: a consistent view of star formation across cosmic time. The project aims to contribute to the answer to a fundamental question: how galaxies, including our own, evolved over the Universe's history. The project plans to develop sophisticated spectral models and use them to extract crucial information on star formation, stellar populations, interstellar gas and dust properties from modern galaxy surveys at different cosmic epochs using a consistent framework. These imaging and sp ....Growing galaxies: a consistent view of star formation across cosmic time. The project aims to contribute to the answer to a fundamental question: how galaxies, including our own, evolved over the Universe's history. The project plans to develop sophisticated spectral models and use them to extract crucial information on star formation, stellar populations, interstellar gas and dust properties from modern galaxy surveys at different cosmic epochs using a consistent framework. These imaging and spectroscopic surveys would be complemented with measurements of the total gas reservoir of galaxies, obtaining a full census of the baryons in galaxies. Together, these may deliver significant insights into how the growth of galaxies, driven by the fuelling, efficiency and outputs of star formation, depends on galaxy properties in the local and distant Universe.Read moreRead less
How do galaxies get their gas? This project aims to build new understanding about the fundamental physics behind how galaxies get their gas. The way gas is accreted in galaxies affects how stars are made and what galaxies look like, including our own milky way. This project expects to build a new robotic instrument for three dimensional spectroscopy of galaxies, called Hector-I, to establish and run the Hector Galaxy Survey, the largest of its kind ever conducted. This survey data set will under ....How do galaxies get their gas? This project aims to build new understanding about the fundamental physics behind how galaxies get their gas.

This project expects to build a new robotic instrument for three dimensional spectroscopy of galaxies, called Hector-I, to establish and run the Hector Galaxy Survey, the largest of its kind ever conducted. This survey data set will underpin broad investigations of gas accretion and the impact on the physical properties of galaxies. The project will clarify why our own galaxy looks so different to others, demonstrate Australian technologies for future commercialisation on international facilities, and train students for a high quality workforce.Read moreRead less
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
