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.

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
Weighing the Universe using fast radio bursts. Fast radio bursts are a newly-discovered astronomical phenomenon whose millisecond-timescale emission occurs at cosmological distances, rendering them exceptional probes of the matter that lies in intergalactic space. This project aims to measure the positions and obtain the distances to these bursts to make a direct measurement of the density of ordinary matter in the Universe, at least 50 per cent of which is believed to remain undetected in inter ....Weighing the Universe using fast radio bursts. Fast radio bursts are a newly-discovered astronomical phenomenon whose millisecond-timescale emission occurs at cosmological distances, rendering them exceptional probes of the matter that lies in intergalactic space. This project aims to measure the positions and obtain the distances to these bursts to make a direct measurement of the density of ordinary matter in the Universe, at least 50 per cent of which is believed to remain undetected in intergalactic space. This project will measure the distribution of this missing matter, and find how it has evolved throughout the history of the Universe. This will provide significant benefits, such as addressing two fundamental questions about our Universe: how much matter does it contain, and has a large fraction of it hitherto evaded detection in intergalactic space?Read moreRead less

Summary
Probing ultralight bosons with black holes and gravitational waves. This project aims to search for gravitational waves from ultralight boson clouds around black holes and to investigate the boson properties. It expects to generate new knowledge on currently undiscovered particles by combining cutting-edge theories and innovative signal-processing techniques. These particles are predicted to solve problems in particle and high-energy physics and are compelling dark matter candidates.

This project aims to search for gravitational waves from ultralight boson clouds around black holes and to investigate the boson properties. It expects to generate new knowledge on currently undiscovered particles by combining cutting-edge theories and innovative signal-processing techniques. These particles are predicted to solve problems in particle and high-energy physics and are compelling dark matter candidates. Expected outcomes include high-profile constraints on the particle properties and potential detection of new particles, new data-analysis techniques, and significantly enhanced capacity to build international and interdisciplinary collaborations. These should bring significant benefits to fundamental physics and cosmology.Read moreRead less
Ultra-sensitive third-generation gravitational wave detectors. Second-generation gravitational wave detectors that will directly detect gravitational waves for the first time are currently being assembled. Their sensitivity will be limited by intrinsic thermal motion of the atoms in the mirror coatings and the quantum nature of the laser beams in the detectors. This project aims to develop new designs with the aim of circumventing these limitations and developing the ultra-sensitive optical metr ....Ultra-sensitive third-generation gravitational wave detectors. Second-generation gravitational wave detectors that will directly detect gravitational waves for the first time are currently being assembled. Their sensitivity will be limited by intrinsic thermal motion of the atoms in the mirror coatings and the quantum nature of the laser beams in the detectors. This project aims to develop new designs with the aim of circumventing these limitations and developing the ultra-sensitive optical metrology required to realise those designs. It is expected that the increased sensitivity of these third-generation detectors will allow more detailed measurement of the gravitational wave signals and provide unprecedented understanding of some of the most violent events in the universe.Read moreRead less

Summary
Equipment and instrumentation for breaking the quantum measurement barrier. This equipment will support Australia's partnership in the international effort to detect gravitational waves, which would allow the first direct observation of black holes and mark the beginning of exploration of the gravitational wave spectrum.
Gravitational wave detection with current and future radio telescopes. This project will aim to detect gravitational waves using precision pulsar timing observations. Direct detection of these waves is of huge international importance and will keep Australia at the forefront of the new research field of gravitational wave astronomy that will continue to grow with the planned radio telescopes of the future.
