Radiation and Ablation in Rapidly Expanding Flows. The aim of the project is to record the spectra of radiation from a region of rapidly expanding flow representative of the passage of the shock layer on a re-entry capsule from the windward to the leeward surfaces. The significance of this work is that it addresses a critical area of spacecraft where the uncertainties of our design techniques are of the order of 300 per cent in terms of surface heat transfer, and current vehicles have to use lar ....Radiation and Ablation in Rapidly Expanding Flows. The aim of the project is to record the spectra of radiation from a region of rapidly expanding flow representative of the passage of the shock layer on a re-entry capsule from the windward to the leeward surfaces. The significance of this work is that it addresses a critical area of spacecraft where the uncertainties of our design techniques are of the order of 300 per cent in terms of surface heat transfer, and current vehicles have to use large safety factors to ensure survivability. The outputs from the project will be a data base of radiative parameters which should enable accurate models of the flow to be developed, which is expected to facilitate the design of advanced spacecraft with greater safety and reliability, and with lower structural mass.Read moreRead less
Physics of Base Flows of Planetary Entry Configurations. Continued investment by Australia in the AHI will help to maintain Australia's leading role in the exciting fields of space research and hypersonics and to encourage future international collaboration. The research will use the unique existing experimental infrastructure (largely ARC funded) for space related research, which will enable Australia to make a valuable contribution to the design of future planetary missions.

The research will use the unique existing experimental infrastructure (largely ARC funded) for space related research, which will enable Australia to make a valuable contribution to the design of future planetary missions. The project will provide a stimulating, exciting and supportive environment for the training of postgraduate and postdoctoral personnel as well as students at the undergraduate level. It will help to motivate young Australians to pursue their interest in science and engineering.Read moreRead less
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.
Linear Formation Interferometry for Astrophysics and New Space Technologies. This project will prototype a new type of visible and infrared light interferometry: telescopes freely moving in a line 10s of metres in length and directing their light towards a central beam combiner. This is particularly well suited to sparse aperture optical interferometry from space, which can be used to resolve angular scales much finer than the world's largest monolithic telescopes. The ground based prototype wil ....Linear Formation Interferometry for Astrophysics and New Space Technologies.

This is particularly well suited to sparse aperture optical interferometry from space, which can be used to resolve angular scales much finer than the world's largest monolithic telescopes. The ground based prototype will also be able to make a several key astrophysical observations of benchmark stars and stellar systems, including making precise polarimetric measurements of dust shells around bright stars.Read moreRead less
Stellar chemical signatures of planet formation. Through demanding observations with the largest telescopes and extremely accurate analyses, the project will search for the characteristic fingerprints of planet formation imprinted in the chemical compositions of the sun and stars that we have discovered. The work will shed light on the origin of the solar system and identify stars harbouring planets.
An upgraded pulsar timing array for gravitational wave detection. Millisecond pulsars are remarkably regularly-rotating neutron stars that offer the opportunity to detect gravitational waves via the technique known as pulsar timing. Australia has long been a world leader in the discovery and timing of millisecond pulsars, and the Parkes pulsar timing array is one of three major programmes in the world aimed at making the first direct detection of gravitational waves in any frequency band. This p ....An upgraded pulsar timing array for gravitational wave detection. Millisecond pulsars are remarkably regularly-rotating neutron stars that offer the opportunity to detect gravitational waves via the technique known as pulsar timing. Australia has long been a world leader in the discovery and timing of millisecond pulsars, and the Parkes pulsar timing array is one of three major programmes in the world aimed at making the first direct detection of gravitational waves in any frequency band. This project is designed to capitalise on Australia's position of strength in this field by extending the Parkes Pulsar Timing Array dataset (PPTA) so that it has the best chance of detecting gravitational waves in the nanohertz regime until the SKA pathfinders start to come online in 2017.Read moreRead less
Detecting cosmic rays using precision radio imaging. This project's aim is to identify the source of the highest-energy particles in nature, cosmic rays, and discover new physical processes at energies unreachable by the Large Hadron Collider.
It will do this by using the Murchison Widefield Array radio telescope to detect the sub-microsecond pulses from cosmic ray interactions in the Earth's atmosphere. The project's intended outcome is a sample of thousands of cosmic ray events, and a new tec ....Detecting cosmic rays using precision radio imaging.

It will do this by using the Murchison Widefield Array radio telescope to detect the sub-microsecond pulses from cosmic ray interactions in the Earth's atmosphere. The project's intended outcome is a sample of thousands of cosmic ray events, and a new technique to analyse the structure within them.
The anticipated benefits are the establishment of the Murchison Widefield Array as a world-leading instrument for astroparticle physics, new knowledge of high-energy astro and particle physics, and advances and training in fast signal processing methods.Read moreRead less

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
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
