This project aims to develop methods for forecasting the evolution of magnetic fields on the Sun's surface, and to use the results to drive an ensemble of numerical simulations of the evolution of the magnetic field in the overlying atmosphere. The project expects to create a new framework for forecasting the evolution of solar active regions, applying, for the first time, methods established in Numerical Weather Prediction. The expected outcomes are physics-based prediction of solar atmospheric magnetic field evolution, including explosive eruptions. The results should have significant benefit in improving prediction of extreme space weather events, which pose an increasing threat to our technologically-dependent society.Read moreRead less

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.

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

A sensitive tip-tilt wavefront sensor for the multi-conjugate adaptive-optics system on the Gemini South telescope: This project will construct a sensitive tip-tilt wavefront sensor for GeMS, the multi-conjugate adaptive-optics system on the Gemini South telescope in Chile. GeMS is a unique and revolutionary new system that delivers near-infrared images at similar resolution to the Hubble Space Telescope at optical wavelengths over wide fields. With this improvement in technology it will be possible to do this on much fainter objects than is currently possible using this new wave-front sensor. This will allow GeMS to routinely study the morphologies of external galaxies at high angular resolution - greatly extending its science scope. Sharper images will also be obtained for all objects that are currently accessible, leading to higher quality science data.Read moreRead less

This project aims to upgrade the $150m CSIRO Australia Telescope Compact Array ("the telescope"), by replacing the signal processing electronics and doubling the bandwidth. This will significantly enhance the performance of the telescope, enabling more ambitious science by the 450 researchers and students who use it each year. For example, it will enable the telescope to study radio counterparts to Gravitational Wave sources, and it will enable it to make detailed observations of initial discoveries made with the Australian Square Kilometre Array Pathfinder and other Australian telescopes. In short, it will enable Australian researchers to do more ambitious research, and make more discoveries, across broad areas of astrophysics.Read moreRead less
