Formation of Supermassive Black Holes. One of the most remarkable discoveries in astronomy is the observation that supermassive black holes, weighing as much as a billion suns, are found in the centers of galaxies, including our own Milky Way. Astronomers do not understand how these black holes came to be, or their role in the evolution of galaxies. This Discovery Project will address these issues by analysing data on supermassive black holes from the local and early universes. Black holes fasci ....Formation of Supermassive Black Holes.

Before Planets: The Mineralogy and Chemistry of Pre-Planetary Disks. Planets form within the circumstellar disks around young stars. Samples of the solid material composing our own primitive disk are found in meteorites and interplanetary dust particles. Using the powerful technique of astronomical mid-infrared spectropolarimetry, we will ascertain the composition of the material existing within the disks around young stars. By studying a range of disk ages we will determine how the composition ....Before Planets: The Mineralogy and Chemistry of Pre-Planetary Disks. Planets form within the circumstellar disks around young stars. Samples of the solid material composing our own primitive disk are found in meteorites and interplanetary dust particles. Using the powerful technique of astronomical mid-infrared spectropolarimetry, we will ascertain the composition of the material existing within the disks around young stars. By studying a range of disk ages we will determine how the composition evolves with time, and what physical processes affect it, in order to better understand how our own solar system formed. Further, we will image these disks in mm-wave molecular emission and constrain their chemistry and rotational properties.Read moreRead less

We will build strong links to leading international institutions, supply high-level training for students in information processing skills, and develop new techniques for data analysis that are directly relevant to future space missions. This will position Australia in space exploration, with potential spin-offs for Australian industry. The science of this project will lead to a breakthrough in our understanding of the structure and evolution of stars and their planets, which will enhance Australia's reputation in these two fields of research.Read moreRead less
Interstellar Physics at the Epoch of Galaxy Formation. With large telescopes and major space observatories, we can finally reach back in time and see how galaxies were assembled in the first few billion years of our Universe. We need to determine how gas forms into stars, how massive black holes feed on and interact with their nascent galaxies, how heavy elements are produced, and how dust obscuration or re-radiation affects observations. This proposal brings a world-class team together to devel ....Interstellar Physics at the Epoch of Galaxy Formation.

We need to determine how gas forms into stars, how massive black holes feed on and interact with their nascent galaxies, how heavy elements are produced, and how dust obscuration or re-radiation affects observations. This proposal brings a world-class team together to develop and apply new and unique pan-spectral tools based on physical models of the interstellar plasma and conceived to determine fundamental parameters of collapsing galaxies.Read moreRead less
How many bright stars of the night sky harbour planets? The search for planets around stars is one of the grand endeavours that defines the modern era of astronomy.

The search for planets around stars is one of the grand endeavours that defines the modern era of astronomy. This project will develop two innovative technologies that will lead this field into new observational terrain: high-contrast aperture masking interferometry at large telescopes, and very narrow angle astrometry at the Sydney University Stellar Interferometer. These new instruments will enable the search for planets around the bright intermediate-mass stars of our southern sky, and will target the critical orbital scales of planets at solar-system scale separations. This encompasses the habitable zone where conditions could support life, and the sample will have immediate impact on fundamental questions of planetary formation.Read moreRead less
The First Deep Infrared Study of the Nearby Galaxy Population. We will conduct two major near-infrared (IR) surveys: The Southern Galactic Cap near-IR survey, and the Local Sphere of Influence survey.

It will measure tiny brightness fluctuations in stars that reveal exquisite details about their internal structures. We propose to develop sophisticated processing algorithms that will allow MONS to measure the brightness fluctuations with unprecedented precision. We will also exploit our new method for detecting oscillations in the brightest stars from the ground using the world's largest telescopes.Read moreRead less
Dying stars, mass loss and the creation of the elements. This project aims to observationally estimate the mass loss rates and the surface chemical enrichments exhibited by low and intermediate-mass stars during their final evolutionary stages. The study has become possible because of new telescopes and instruments just arrived or imminently to arrive. Another part of the project is to use the observations to calibrate theoretical models for the evolution of dying stars. Such models are requi ....Dying stars, mass loss and the creation of the elements. This project aims to observationally estimate the mass loss rates and the surface chemical enrichments exhibited by low and intermediate-mass stars during their final evolutionary stages. The study has become possible because of new telescopes and instruments just arrived or imminently to arrive. Another part of the project is to use the observations to calibrate theoretical models for the evolution of dying stars. Such models are required for an understanding of the chemical enrichment of the universe from the time of first star formation to the present.

Venturing into the Cluster Desert. Fundamental questions that ask about the nature and the fate of the Universe are of interest not only to astronomers, but also to the general public. In particular, the realisation that the Universe is dominated by dark energy has sparked wide public interest. We still know very little about dark energy. Is it Einstein's famous cosmological constant or something more exotic, such as a new particle or even new physics? This proposal aims to build a sample of ver ....Venturing into the Cluster Desert. Fundamental questions that ask about the nature and the fate of the Universe are of interest not only to astronomers, but also to the general public. In particular, the realisation that the Universe is dominated by dark energy has sparked wide public interest. We still know very little about dark energy. Is it Einstein's famous cosmological constant or something more exotic, such as a new particle or even new physics? This proposal aims to build a sample of very distant galaxy clusters that can then be used to search for a very special type of supernova - the Type Ia Supernova, which can be used as a tool to learn about the properties of dark energy.
