Precision Pulsar Timing and its Applications. The rapidly rotating pulsars known as millisecond pulsars have period stabilities which rival that of the best terrestrial clocks. Observations of many millisecond pulsars spread across the sky should allow detection of the gravitational-wave background - likely to be the first direct detection of gravity waves. It will also enable establishment of a long-term time standard which is independent of and probably superior to that derived from terrestria ....Precision Pulsar Timing and its Applications.

New analysis techniques and establishment of an international observing network will be required. Investigation and application of techniques for overcoming radio interference will be an important part of the project.Read moreRead less
Defeating Radio Frequency Interference. The radio spectrum is a valuable resource. Development of techniques which minimize the impact of various users on one another, allowing this resource to be shared, will benefit the entire community. For astronomy in particular, shared use is essential because of the very wide bandwidths needed to obtain sufficient sensitivity. Usage of the radio spectrum is increasing rapidly and radio telescopes are becoming more and more sensitive, compounding the probl ....Defeating Radio Frequency Interference. The radio spectrum is a valuable resource. Development of techniques which minimize the impact of various users on one another, allowing this resource to be shared, will benefit the entire community. For astronomy in particular, shared use is essential because of the very wide bandwidths needed to obtain sufficient sensitivity. Usage of the radio spectrum is increasing rapidly and radio telescopes are becoming more and more sensitive, compounding the problems. The digital signal processing techniques developed under this project will be widely applicable, not only to future radio astronomy facilities such as the Square Kilometer Array, but also to the communications industry generally.Read moreRead less
Massive black holes in the hearts of galaxies. This research will create new insights into the extreme physics of supermassive black holes at the centres of galaxies. Using new instrumentation and analysis techniques to measure the polarisation and variability of their radiation, we will develop models for the infall of gas, the structures surrounding black holes and the merger of massive black holes over cosmic time. The new observing modes that we will develop will provide stepping stones to ....Massive black holes in the hearts of galaxies.

The new observing modes that we will develop will provide stepping stones toward the Square Kilometre Array, a multi-billion dollar project from which Australia stands to reap enormous scientific and economic benefit. The major advances that we will deliver will boost Australia's already outstanding track record as a world leader in astronomical discovery.

Extreme events: mining the radio sky for gamma-ray bursts with intelligent algorithms. Gamma-ray bursts and supernova explosions are some of the most extreme events in the Universe, and working out what causes them, and other transient phenomena, will give us new physical insights. The project will search, using next generation telescopes and intelligent algorithms, to find these 'needles in a haystack'.
International partnership in robotic astronomy and gravitational wave data analysis using a supercomputer. The project is aimed at providing student participation in frontier research using robotic astronomy and novel data analysis methods. It will focus on the study of the most violent explosions in the Universe - cosmological gamma ray bursts. These cataclysmic events possibly herald the formation of the most exotic objects in the Universe - black holes. It provides an exciting opportunity for ....International partnership in robotic astronomy and gravitational wave data analysis using a supercomputer.

A clearer view of the evolving universe. The two complementary research objectives of this proposal are (i) a basic research program to understand star formation in galaxies through a study of the correlation betwen far infrared and radio continuum emission and (ii) a strategic research program to develop interference mitigation techniques to enable the next generation of radio telescopes which will study star formation in the early Universe.

This programme of research innovation in radio astronomy will also promote the broad aims of furthering opportunities for Australian participation in international science and of gaining insight into ways in which Australia can exploit its niche advantages in the global economy.Read moreRead less
The Southern Sky Survey. The Southern Sky Survey will create the first digital map of the southern sky, providing a community available database of a billion objects. This database will be used by entire community, with our group targetting four key areas including: studying the creation of our solar system through a census of distant asteroids, exploring how stars and planets form by observing nearby young stars, probing the shape and extent of the Galaxy's dark matter halo, and discovering whe ....The Southern Sky Survey.
