The morphological evolution of galaxies over cosmic time. Present-day galaxies look either red and round or blue and disc-like; this project will study galaxies that existed when the universe was one quarter its present age to understand how these different structures came about. To do this, the project will use a new high resolution near-infrared camera built at The Australian National University.
The High Time Resolution Radio Universe. The radio sky is blanketed by charged particles in the interstellar medium that smear impulsive emissions. By constructing a new digital electronic device for the giant Parkes radio telescope we will be able to divide the radio sky up into many thousands of radio "channels", which when searched on a supercomputer, will enable us to peer into the heart of our Galaxy in search of short bursts of emission. This will be the first large-scale search of the Uni ....The High Time Resolution Radio Universe.

Galactic Archaeology: A Radial Velocity Experiment to Unveil the History of the Milky Way. The ambitious RAdial Velocity Experiment (RAVE) will measure velocities and chemical properties of 50 million stars in the period 2006-2010 - 2000 times the number measured throughout history. RAVE will use a new-technology Australian fiber spectrometer at the Siding Spring UK Schmidt Telescope. A key demonstrator for RAVE is our proposed pilot survey using existing instruments to measure 100,000 stars - a ....Galactic Archaeology: A Radial Velocity Experiment to Unveil the History of the Milky Way. The ambitious RAdial Velocity Experiment (RAVE) will measure velocities and chemical properties of 50 million stars in the period 2006-2010 - 2000 times the number measured throughout history. RAVE will use a new-technology Australian fiber spectrometer at the Siding Spring UK Schmidt Telescope. A key demonstrator for RAVE is our proposed pilot survey using existing instruments to measure 100,000 stars - already 20 times larger than any previous survey - providing unique chemical and kinematical fingerprints of our Galaxy's formation. This is critical for determining the optimum observing strategy, data management, and software pipeline, before embarking on the full survey in 2006.Read moreRead less
The Last 8 Billion Years of Cosmic Evolution. A key factor in Australia's international prominence in astronomy has been the development and use of innovative instrumentation on its telescopes to undertake major leading-edge surveys. This project will enhance this reputation by using the new AAOmega facility on the 3.9m Anglo-Australian Telescope to make the largest ever survey of galaxies in the distant universe. This will allow us to address the two most important issues in cosmology today - ....The Last 8 Billion Years of Cosmic Evolution. A key factor in Australia's international prominence in astronomy has been the development and use of innovative instrumentation on its telescopes to undertake major leading-edge surveys. This project will enhance this reputation by using the new AAOmega facility on the 3.9m Anglo-Australian Telescope to make the largest ever survey of galaxies in the distant universe. This will allow us to address the two most important issues in cosmology today - the nature of the "dark energy" that is causing the universe's expansion to accelerate, and the detailed role of dark matter in galaxy formation and evolution.

It will involve world-leading research in these areas, enabled by innovative instrumentation on Australia's national telescope facilities. National benefit will also come via the collaborations it will involve with prestigious North American institutions. These collaborations will lead to new research capability being built within Australia, through knowledge and expertise being vested in young postgraduate and postdoctoral researchers.Read moreRead less
Advancing and applying stellar nucleosynthesis: using stars to probe galaxies. The project will determine how the lives of stars produce the elements that make up our world, and use this knowledge to look into how our galaxy formed. The project will use the latest results from super-computer studies as well as new instruments being built for Australia's largest optical telescope.
Illuminating the cosmic web with Fast Radio Bursts. This project aims to establish the use of millisecond-duration Fast Radio Bursts as a wholly new means to map out the distribution of matter in the Universe. This project expects to localise 100s of bursts using novel infrastructure deployed on Australia's largest radio telescopes.

This project aims to establish the use of millisecond-duration Fast Radio Bursts as a wholly new means to map out the distribution of matter in the Universe. This project expects to localise 100s of bursts using novel infrastructure deployed on Australia's largest radio telescopes. Expected outcomes include an understanding of the processes that shape both the large-scale structures of the Universe, and the extreme conditions that exist at the sites of Fast Radio Bursts. This should provide significant benefits to our fundamental knowledge of the Universe, inspire students into careers in science, technology, engineering and mathematics, and develop signal processing techniques of application to both the Square Kilometre Array and industry.Read moreRead less
New Pulsar Instrumentation for Gravitation Wave Detection and Understanding the Emission Mechanism. Millisecond pulsar timing currently provides the most sensitive method of detecting long-period gravitational waves which permeate the Universe. Parkes leads the world in the discovery and timing of millisecond pulsars. This has motivated the development of three new advanced instruments including a cyrogenic dual-band receiver, a very wide-band correlator and a baseband recorder with an in-built ....New Pulsar Instrumentation for Gravitation Wave Detection and Understanding the Emission Mechanism. Millisecond pulsar timing currently provides the most sensitive method of detecting long-period gravitational waves which permeate the Universe. Parkes leads the world in the discovery and timing of millisecond pulsars. This has motivated the development of three new advanced instruments including a cyrogenic dual-band receiver, a very wide-band correlator and a baseband recorder with an in-built supercomputer. We aim to exploit these new technologies to systematically study the pulsar population. We will establish a timing array which can detect gravitational waves, enable GLAST to identify over 100 gamma-ray pulsars and study the pulsar emission mechanism at sub-microsecond time resolution.
