Resolving the interstellar carbon crisis with multilaser spectroscopy. This project aims to provide astronomers of the future with firm diagnostic tools to identify and understand exotic carbon species in the interstellar medium. Life on Earth began after delivery of carbon-based pre-biotic material to the young planet by comets and meteorites. This material came from outside the solar system, but we do not yet know the chemical make-up of the interstellar matter.

This project aims to provide astronomers of the future with firm diagnostic tools to identify and understand exotic carbon species in the interstellar medium. Life on Earth began after delivery of carbon-based pre-biotic material to the young planet by comets and meteorites. This material came from outside the solar system, but we do not yet know the chemical make-up of the interstellar matter. This is because we do not understand precisely how the interstellar molecules and dust interact with starlight. This project will create and study models of interstellar matter in the laboratory, and will determine the chemical form of carbon in the interstellar medium. This will have lasting impact on astrophysical models, as well as theories of the origin of life.Read moreRead less

Summary
Pioneering measurements of hidden gas in our Milky Way Galaxy. This project aims to measure hidden gas in our Milky Way Galaxy. The dynamic transformation of diffuse gas to dense clouds and then to stars is a crucial component of how galaxies function. Recent work implies vast reservoirs of undetected gas intermediate between the diffuse and dense phases – a missing link connecting diffuse gas to star-forming clouds. This project aims to uncover that hidden gas, using radio spectral line observa ....Pioneering measurements of hidden gas in our Milky Way Galaxy. This project aims to measure hidden gas in our Milky Way Galaxy. The dynamic transformation of diffuse gas to dense clouds and then to stars is a crucial component of how galaxies function. Recent work implies vast reservoirs of undetected gas intermediate between the diffuse and dense phases – a missing link connecting diffuse gas to star-forming clouds. This project aims to uncover that hidden gas, using radio spectral line observations and theoretical models to understand its role as an intermediary on the road to star formation. These results are expected to change understanding of how galaxies form and evolve from the early universe to the present day.Read moreRead less
The scale and structure of the Milky Way. This project aims to use new Australian infrastructure to make the most accurate distance measurements to date in the southern Milky Way, completing the three-dimensional picture of our Galaxy. Australia's international standing in astronomy has led to it being one of the host countries for the square kilometre array project, which will bring significant economic and technological benefits to the country. This project builds upon Australia's astronomical ....The scale and structure of the Milky Way.

Australia's international standing in astronomy has led to it being one of the host countries for the square kilometre array project, which will bring significant economic and technological benefits to the country. This project builds upon Australia's astronomical expertise and will provide the most accurate picture to date of the Milky Way. Astronomy provides unique opportunities for engaging the community in discussions of science and society and inspires students to study STEM subjects.Read 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.
Unveiling the Galaxy: Dense Gas and Star Formation in the Milky Way. This project aims to address one of the most fundamental problems in astrophysics - understanding how high-mass stars form - by utilising a new, innovative, purpose-designed astronomical survey. This project will generate new knowledge about the star formation process by interfacing theoretical predictions with novel observations, aided by the most accurate distances yet derived. Expected outcomes include a comprehensive unders ....Unveiling the Galaxy: Dense Gas and Star Formation in the Milky Way. This project aims to address one of the most fundamental problems in astrophysics - understanding how high-mass stars form - by utilising a new, innovative, purpose-designed astronomical survey. This project will generate new knowledge about the star formation process by interfacing theoretical predictions with novel observations, aided by the most accurate distances yet derived. Expected outcomes include a comprehensive understanding of star formation, and an unparalleled map of the dense gas structure of our Galaxy. This should provide significant benefits, such as the crucial insight needed to interpret future sensitive, high-resolution surveys with next generation, globe-spanning telescopes in which Australia is a key partner.Read moreRead less
Galactic archaeology: a radial velocity experiment to unveil the history of the Milky Way. The goal of the international RAdial Velocity Experiment (RAVE) survey is to measure velocities and chemical properties of 500,000 stars, using the Schmidt telescope at Siding Spring Observatory; the survey was conceived by Australians and involves astronomers from 10 countries. This is the basic information that we need to understand how the Milky Way formed and evolved.
A survey of the interstellar medium in the Milky Way and Magellanic Clouds using the Australian Square Kilometre Array Pathfinder. Between the stars in the Milky Way there are clouds of gas and dust; old stars eject heavy elements into this interstellar medium, and new stars form when interstellar clouds collapse under their own gravity. This survey is making maps of the interstellar gas using spectral lines at radio wavelengths to trace the cycle of star formation.

Summary
Tracing the evolution of high-mass stars: combining maser evolutionary timelines with chemical clocks. Maser emission (radio analogue of lasers) arises naturally in the dense gas surrounding young, large stars. Studying many types of masers towards lots of sources will allow us to uncover the precise stages of star formation that each maser species is tracing. Such a timeline promises to be an important tool in determining how these big stars form.

Summary
Defining the dynamic magnetised Milky Way. Without understanding how the Milky Way works, it is incredibly difficult to understand the evolution and structure of more distant galaxies. This research will show how the pieces of our Galaxy, including the impact of the mysterious force of magnetism, fit together and move around in space, defining a new image of the Milky Way.

This project aims to advance our knowledge of globular clusters. The study of the newly discovered generations of stars in globular clusters constitutes a modern branch of stellar and galactic astrophysics. The project plans to provide a chemical characterisation of the multiple stellar populations present in globular clusters, and explore the nature of these ancient stellar systems and their possible connection with dwarf galaxies. The outcome of this research may help us understand the formation mechanisms of the Milky Way and the contribution of globular clusters to the galactic halo assembly, and may open unexpected solutions for the ‘missing satellites problem’ – the lack of low-mass galaxies compared to the predictions of the Big Bang model.Read moreRead less
