The project aims to advance the symbiotic relation between astronomy and machine learning to unravel the origin and the evolutionary history of the Milky Way. The proposed study will base heavily on the data from the Australian-led spectroscopic survey and, as a result, contribute to realising the full potential of this multi-million dollar endeavour. The goal of the study is to walk ourselves back in cosmic time, using the most advanced technologies of our time to reveal the Milky Ways oldest story. The investigation aims to consolidate Australia's position in big data astronomy and give Australia a unique competitive advantage in data analytics. Such an endeavour is essential for Australia to maintain its leadership in astronomy.Read moreRead less

Summary
The Cherenkov Telescope Array - From Production towards Operation. The Cherenkov Telescope Array is a transformational facility in very-high-energy gamma-ray astronomy. It will be 10 times more sensitive than current instruments and will revolutionise many topics in high energy astrophysics, and in astro-particle physics such as dark matter. Over 1000 scientists from over 30 countries are involved and the first telescopes on the southern hemisphere site in Chile will be installed from about 2021 ....The Cherenkov Telescope Array - From Production towards Operation.

This project aims to ensure Australia’s contribution to the five-year production phase of the Cherenkov Telescope Array (CTA), a very high energy gamma-ray astronomy instrument that is expected to transform both high energy astrophysics and astro-particle physics. Gamma-ray astronomy probes extreme processes in the Universe such as exploding stars, black holes, and mysterious dark matter. The project will maintain Australian access to all data and key science programmes of the CTA. Australian astronomers will be able to directly influence the major astrophysics goals of CTA, and link in with Australia's flagship astronomical infrastructure. This is expected to benefit astrophysics, big data processing, electronics, atmospheric physics and optics.Read moreRead less
The convective boundaries in stars. This project aims to locate the boundaries of convection, a problem in models of stars. It will calculate high-resolution three-dimensional simulations of stars and observe star clusters. The effect of this advance on stellar modelling could be profound since almost all stars contain convective regions. Many branches of astronomy rely on stellar models so the effect could extend far beyond the immediate field, ultimately expanding understanding of the Universe ....The convective boundaries in stars.

The effect of this advance on stellar modelling could be profound since almost all stars contain convective regions. Many branches of astronomy rely on stellar models so the effect could extend far beyond the immediate field, ultimately expanding understanding of the Universe. It could also be crucial in realising the scientific advances of the surveys which are gathering data for up to a billion stars.Read moreRead less
Galactic seismology: a new window on Milky Way's evolution. This project aims to investigate how the Milky Way responds to the passage of a small dwarf galaxy through its plane. This is motivated by the observational discovery of largescale waves crossing the Milky Way disc, and by new related supercomputer simulations.

The project expects to generate new knowledge in this field, based on further supercomputer simulations and comparison of the predictions with new data from the Gaia space mission. Expected outcomes of the project include a demonstration of the diagnostic power of this new seismological approach to galaxy evolution. The project promises significant benefits in the form of establishing Australia as a leader in Galactic seismology, as it is in the field of Galactic archaeology.

Using vast new data samples to understand the disk of the Milky Way. How did disk galaxies like our Milky Way form from the expanding universe? This project seeks to improve our models of this process. Numerical models informed by observation are the key to understanding galaxy formation.

This project seeks to improve our models of this process. Numerical models informed by observation are the key to understanding galaxy formation. The models predict the properties of galaxies in detail, but must be tested and modified relative to the observed motions and chemical properties of stars in the Galactic disk. Adequate data is essential but not yet available. This is about to change. This project plans to use observations from two vast new surveys to measure the chemical properties and motions of a million disk stars, in order to inform the numerical models properly. It also plans to use new techniques to search for chemical fingerprints of intense star formation events in galactic disks in the early universe.Read moreRead less
The life-stories of galaxies from stellar fossils. This project aims to derive stellar ages and chemical compositions to draw the precise evolutionary history of the Galaxy, using ongoing observational programmes.

This project aims to derive stellar ages and chemical compositions to draw the precise evolutionary history of the Galaxy, using ongoing observational programmes. Stars hold the key to unveil the events that occurred throughout the history of our Galaxy, from the beginning of time until today. Their atmospheres retain a fossil record of the composition of the interstellar medium at the time of their formation, and the twinkling of their light tells us about their ages. Combining data from space-borne satellites and large Australian ground-based surveys is expected to lead to understanding of galaxy formation as a whole.Read moreRead less
Explosive evidence: connecting stellar abundances to supernova progenitors. This project aims to determine the evolutionary scenarios of thermonuclear supernovae through numerical simulations. Supernova explosions create heavy elements, such as iron, that enable life on Earth, and are instrumental in proving that the Universe is expanding at an accelerating rate. For all their importance, the nature of their progenitors is still a mystery, which has implications for many fields of astrophysics. ....Explosive evidence: connecting stellar abundances to supernova progenitors.

Supernova explosions create heavy elements, such as iron, that enable life on Earth, and are instrumental in proving that the Universe is expanding at an accelerating rate. For all their importance, the nature of their progenitors is still a mystery, which has implications for many fields of astrophysics. Through building inter-institutional and international collaborations, the project is expected to determine where, when, and how often these explosions occur. Benefits will include development of new technological methods and exploitation of Australian-led survey data from national facilities.Read moreRead less
