DYNAMICS OF EARTH'S RADIATION BELTS. Space weather is produced by rapid variations in wave fields and particle populations in near-Earth space, and has many effects. These include damage to spacecraft (causing operational anomalies and loss of service), degrading the performance of GPS, space-ground, HF radio and cable-based networks, and affecting surveillance radars. The core aim of this project is to improve knowledge of the waves and particles causing these effects. While being important to ....DYNAMICS OF EARTH'S RADIATION BELTS.

The core aim of this project is to improve knowledge of the waves and particles causing these effects. While being important to aerospace engineers, this work also consolidates Australia's international space profile and provides excellent training in this field. Since space weather causes significant radiation exposure to aircraft crew and passengers this work also has broader ramifications.Read moreRead less
Ring Current and Radiation Belt Dynamics. Outbursts of energy from the Sun manifest themselves as geomagnetic storms in the Earth's magnetosphere. These storms can severely disrupt and damage advanced technological systems operating on the ground and in space. Operational spacecraft may experience anomalies, pipelines in the long term may corrode and the performance of GPS navigational systems, HF (High Frequency) communications systems, mobile/cell telephone networks and defence surveillance ra ....Ring Current and Radiation Belt Dynamics. Outbursts of energy from the Sun manifest themselves as geomagnetic storms in the Earth's magnetosphere. These storms can severely disrupt and damage advanced technological systems operating on the ground and in space. Operational spacecraft may experience anomalies, pipelines in the long term may corrode and the performance of GPS navigational systems, HF (High Frequency) communications systems, mobile/cell telephone networks and defence surveillance radars may be degraded. It is important to understand the magnetospheric conditions contributing to these problems. This research identifies relevant mechanisms. It also enhances Australia's international space research profile, contributes to Australia's future and supports excellent postgraduate training.Read moreRead less
Electromagnetic Ion Cyclotron Waves and Magnetosphere Plasma Dynamics. Space weather, manifest as magnetic storms in the Earth's magnetosphere, can severely disrupt and damage advanced technological systems operating in space and on the ground.

Space weather, manifest as magnetic storms in the Earth's magnetosphere, can severely disrupt and damage advanced technological systems operating in space and on the ground. Spacecraft may experience operational anomalies, pipeline corrosion may eventuate in the long term, and the performance of GPS navigation systems, HF communication systems, mobile phone networks, and surveillance radars, may be degraded. Knowledge of the near-Earth space environment under which these problems occur is extremely important. This project identifies relevant mechanisms. The research consolidates Australia's international space profile, provides excellent postgraduate training in the field, and contributes to Australia's future technological development.Read moreRead less
Ground based monitoring of plasma dynamics in the magnetosphere. We will use a new technique to study the plasmapause, a fundamental and highly dynamic boundary in geospace. This is usually examined using spacecraft and ground-based VLF measurements, but these suffer several limitations. We have developed the ability to monitor plasma density in geospace, by measuring the resonant frequency of geomagnetic field line oscillations.

We will use a new technique to study the plasmapause, a fundamental and highly dynamic boundary in geospace. This is usually examined using spacecraft and ground-based VLF measurements, but these suffer several limitations. We have developed the ability to monitor plasma density in geospace, by measuring the resonant frequency of geomagnetic field line oscillations. This project will use data from extensive ground magnetometer arrays to thus study the spatial and temporal variation in particle density near the plasmapause. Comparison with VLF and spacecraft measurements will provide new information on the plasma composition and dynamics in this important region.Read moreRead less

Australian astronomers have a long history in innovative instrumentation and are some of the early pioneers in infrared astronomy. The GNOSIS project brings together leading Australian astronomers to build on past success. This facility instrument makes use of recent technological advances in photonics—a key strength of Australian research and industry—to provide a dramatic improvement in observational sensitivity at these wavelengths. This will allow Australian astronomers to carry out new science programmes that have not been possible to date. These programmes include unprecedented observations of very cool low mass stars, the first chemical information on dust-embedded star clusters, and accurate ages for distant galaxies.Read moreRead less

The collaboration between the ANU research group and European Aeronautic Defence and Space Company (EADS) ASTRIUM, the largest European aerospace company, is a unique opportunity for Australia to capitalize on the new discovery of the Helicon Double Layer Thruster made at the ANU. This will allow the Australian space community to stay abreast of international developments in space propulsion and to be with the forerunners of this new technology. ANU will have direct access to EADS-ASTRIUM via the relationships developed in this project putting Australia in the enviable position of being an insider in future space developments concerning plasma thrusters and space technology in general.Read moreRead less
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.

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 fascinate students both young and old. This Discovery Project will train a new generation of young Australian astronomers at the leading edge of astrophysics.

Samples of the solid material composing our own primitive disk are found in meteorites and interplanetary dust particles.

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
