This DP team, a world-class team of observers and theorists, will tackle this question by leveraging on two multi-million dollar projects: the MAGPI galaxy survey and the hydrodynamical simulations suite EAGLE-XL. MAGPI will deliver exquisite kinematics for hundreds of galaxies in the middle ages of the Universe, providing a view to the effect of dark matter on galaxies at this critical time, while EAGLE-XL represents the technological frontier in simulations and provides the best interpretative framework for MAGPI.Read moreRead less

Summary
Gas in the Cosmic Web: feeding and feedback of galaxies. This project aims to understand the complete cycle of gas in galaxies: from the process of feeding galaxies, going through star formation, to the process of outflowing gas from galaxies. This requires a full physical description of the inflow of gas from filaments going through the halo until reaching galaxies, the process of star formation in a multi-phase gas medium, and the effect energetic events have on the gas content of galaxies. Th ....Gas in the Cosmic Web: feeding and feedback of galaxies. This project aims to understand the complete cycle of gas in galaxies: from the process of feeding galaxies, going through star formation, to the process of outflowing gas from galaxies. This requires a full physical description of the inflow of gas from filaments going through the halo until reaching galaxies, the process of star formation in a multi-phase gas medium, and the effect energetic events have on the gas content of galaxies. This project in the field of extragalactic astrophysics is designed to complement major observational efforts in Australia, such as the Square Kilometre Array and its Pathfinder, as it will provide simulations with full physical descriptions of the neutral gas in the Universe.Read moreRead less

Radio astronomy is entering a new era, driven by technological advances that make rapid surveys of the sky possible. As leaders of three major surveys for the Australian Square Kilometre Array Pathfinder (ASKAP) telescope, we will explore three new dimensions of astronomy: searching for transient sources, detecting faint galaxies and investigating cosmic magnetism. The project will put Australian astronomers at the forefront of international research. In addition to novel scientific results we will produce data resources and software that will be critical for future Square Kilometre Array projects. These will be available online to amateur astronomers and the general public. We will train the next generation of astronomers with the skills required to make breakthrough discoveries.Read moreRead less

Weighing the Giants: Using Galaxy Clusters to understand Dark Energy. This project seeks to reveal the nature of dark energy and thereby explain what is causing expansion of the Universe to accelerate. The project will develop new deep machine learning techniques to weigh galaxy clusters, and apply them to data from the SPT-3G experiment at the South Pole. By comparing theoretical predictions to the observed numbers and masses of galaxy clusters, the project will help determine whether the accel ....Weighing the Giants: Using Galaxy Clusters to understand Dark Energy. This project seeks to reveal the nature of dark energy and thereby explain what is causing expansion of the Universe to accelerate. The project will develop new deep machine learning techniques to weigh galaxy clusters, and apply them to data from the SPT-3G experiment at the South Pole. By comparing theoretical predictions to the observed numbers and masses of galaxy clusters, the project will help determine whether the acceleration is due to dark energy or a breakdown in general relativity. The data science training received by students and researchers on the project will also contribute to a highly skilled STEM workforce for Australia.

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.

Summary
The SAMI facility: a revolutionary multi-object hexabundle spectrograph. SAMI is a new Australian instrument concept that uses fibre bundles to obtain detailed spectroscopic data at many positions across the face of numerous galaxies at a time. Now that the technology has been shown to work, with spectacular results, the project aims to turn this concept into a general-user facility at the Anglo-Australian Telescope.
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

Summary
New high precision, direct measurement of the dark matter distribution. How do you measure what you cannot see? Using a radically new and exquisitely sensitive technique called Direct Shear Mapping, which works by measuring the curvature of space-time around massive objects, this project will make the first ever direct measurements of the dark matter halos surrounding approximately 100 individual galaxies in the local Universe.
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
