Space debris is a growing international threat to all major economies that rely on space for communications and defence. This project will understand how defunct satellites degrade over time to produce space debris. To accomplish this the project will collaborate with the Polish Space Agency to employ low resolution spectroscopy to measure the surface degradation of geostationary satellites. Read moreRead less

Summary
A database for Australian optical astronomy. We will build an astronomy data facility to provide database facilities to analyse data from three major Australian optical astronomy projects, SkyMapper, WiggleZ and GAMA. The facility will provide efficient analysis tools not only for the researchers immediately involved with the projects, but, for the entire national and international astronomical community when the data become public. Long-term maintenance of the facility is vital, so the facilit ....A database for Australian optical astronomy. We will build an astronomy data facility to provide database facilities to analyse data from three major Australian optical astronomy projects, SkyMapper, WiggleZ and GAMA. The facility will provide efficient analysis tools not only for the researchers immediately involved with the projects, but, for the entire national and international astronomical community when the data become public. Long-term maintenance of the facility is vital, so the facility will be standards-compliant and stable to facilitate long-term support. For this reason the facility will be based at the ANU Supercomputer Facility (ANUSF) to leverage substantial expertise in this area and to provide long-term operations support.Read moreRead less
Structure and Evolution of High Brightness Temperature Cores of Quasars and Galaxies. Interstellar scintillation, ISS, is a revolutionary new and powerful technique which we will use to study the highest brightness temperature cores of radio quasars with unprecedented angular resolution, and probe the interstellar medium of our Galaxy in a way not previously possible. The combination of scintillation and conventional VLBI allows imaging with light-month to light-year resolution across the known ....Structure and Evolution of High Brightness Temperature Cores of Quasars and Galaxies. Interstellar scintillation, ISS, is a revolutionary new and powerful technique which we will use to study the highest brightness temperature cores of radio quasars with unprecedented angular resolution, and probe the interstellar medium of our Galaxy in a way not previously possible. The combination of scintillation and conventional VLBI allows imaging with light-month to light-year resolution across the known Universe. Scintillation observations are challenging basic synchrotron physics by uncovering quasar cores with temperatures possibly as high as 10^15 K, and lifetimes many times longer than theory. The Ceduna and Hobart telescopes are cornerstones of our scintillation and VLBI proposals.

Expanding our view of the Universe with the Murchison Widefield Array:
This project aims to build a Phase 2 Murchison Widefield Array (MWA) to boost the capabilities of the Phase 1 MWA by an order of magnitude. The Epoch of Reionisation (EoR), when the first stars and galaxies lit up the universe, is the last unstudied phase of cosmic evolution. The MWA is at the frontier of EoR research and all-sky survey astrophysics, is the only low frequency precursor for the Square Kilometre Array (SKA), and is the only SKA precursor delivering science quality data. This project to construct a Phase 2 MWA would double the number of antennas in the array, double the maximum baseline length, and boost our all-sky survey and EoR capabilities. Read moreRead less
Studies of the Highest Energy Particles in Nature. One of the greatest mysteries of modern astrophysics is the origin of the highest energy cosmic rays. While rare, these subatomic particles possess enormous energies, some 100 million times larger than we can impart to a proton in man-made accelerators. Theory struggles to identify cosmic ray acceleration mechanisms, but these particles do exist.

Theory struggles to identify cosmic ray acceleration mechanisms, but these particles do exist.

This project aims to improve the sensitivity of the Advanced Laser Interferometer Gravitational wave Observatory (aLIGO). aLIGO’s detection of gravitational waves proved general relativity in the strong field limit and the existence of black hole binary systems. The increased sensitivity will enable daily detections and new classes of events, opening the field of gravitational wave astronomy. Since telescopes can detect only 5% of the stuff in the universe, this is expected to greatly improve understanding of the universe. This Australian partnership will put its physicists and astronomers at the vanguard of this field and inspire the next generation to study the physical sciences.Read moreRead less

This project expects to enhance our understanding of how this solar wind is accelerated and structured using a suite of state-of-the-art computational simulations. In doing this, the project expects to provide critical physical understanding to allow interpretation of data from NASA and ESA's flagship space missions Parker Solar Probe and Solar Orbiter. Benefits should include enhanced physical understanding that will contribute to the international effort to develop reliable space-weather forecasting systems, critical for space exploration and space-based technology.Read moreRead less

It is still unknown if any of the candidate objects possess the key black hole feature -- a trapped region from which no signal can escape. By focusing on conditions for existence of trapped regions, this project expects to describe their neighborhoods and observable properties. This information is critical for interpretation of the data from the next generation of gravitational wave detectors and radio telescopes, and for determining the true nature of astrophysical black hole candidates. Further benefits include simplification of calculations of the observable properties of compact objects and resolution of a long-standing black hole information loss paradox.Read moreRead less

This project aims to improve spectrographic design in order to increase precision in astronomical research. The discovery of Earth's twin, a habitable world in another stellar system, is one of the most remarkable scientific endeavours of our time. The gravitational tug of the planet on its host star causes a periodic Doppler shift of the star’s spectrum which is recorded using spectrographs. The instrumental precision required to detect an Earth-like planet is a few centimetres per second, significantly better than the best current spectrographs can provide. This project plans to combine novel technologies from adaptive optics and astrophotonics into an innovative spectrograph design that will improve Doppler precision by a factor of ten, sufficient to find planets.Read moreRead less
