Enhancing gravitational wave detector sensitivity and bandwidth for astronomy. This project aims to create small optomechanical devices that amplify the signals in gravitational wave detectors, increasing their sensitivity, especially for higher frequency signals. Calibrated against the 2015 first detection of gravitational waves from black hole mergers, this technology could allow humanity to listen to black holes merging up to 30 times every day, while giving much greater sensitivity to signal ....Enhancing gravitational wave detector sensitivity and bandwidth for astronomy. This project aims to create small optomechanical devices that amplify the signals in gravitational wave detectors, increasing their sensitivity, especially for higher frequency signals. Calibrated against the 2015 first detection of gravitational waves from black hole mergers, this technology could allow humanity to listen to black holes merging up to 30 times every day, while giving much greater sensitivity to signals from smaller black holes and neutron stars. The new technology, which uses nano-scale suspended tiny mirrors controlled by laser light, is likely to have applications in making sensors and quantum devices for advanced instrumentation, improve mineral exploration and measure tiny electromagnetic signals.Read moreRead less
Metamaterials for control of acoustic radiation forces. This project aims to investigate how sound waves exert forces on objects, and how these forces can be controlled by artificially engineered structures known as acoustic metamaterials. The project is expected to lead to a new understanding of acoustic radiation forces, and how they can be efficiently manipulated with high resolution. The expected outcome is a new capability for the measurement of delicate mechanical structures, which avoids ....Metamaterials for control of acoustic radiation forces. This project aims to investigate how sound waves exert forces on objects, and how these forces can be controlled by artificially engineered structures known as acoustic metamaterials. The project is expected to lead to a new understanding of acoustic radiation forces, and how they can be efficiently manipulated with high resolution. The expected outcome is a new capability for the measurement of delicate mechanical structures, which avoids the cost, complexity and side-effects of existing systems. This should benefit many high-tech areas, including inflatable space structures, micro-mechanical sensors and actuators and precise optical components, as well as biological areas such as the study of insect flight and communication.Read moreRead less

Summary
Australian Partnership in Advanced LIGO+: continuation. The aim of this project is, in collaboration with the USA and UK, to complete the installation and commissioning of the Advanced LIGO+ facilities in the USA in order to bring them to design sensitivity. These facilities expect to increase the event rate of gravitational wave signals by a factor of 125. This should lead to daily detections and the observation of new sources of gravitational waves. Given that only 5% of the universe is detect ....Australian Partnership in Advanced LIGO+: continuation. The aim of this project is, in collaboration with the USA and UK, to complete the installation and commissioning of the Advanced LIGO+ facilities in the USA in order to bring them to design sensitivity. These facilities expect to increase the event rate of gravitational wave signals by a factor of 125. This should lead to daily detections and the observation of new sources of gravitational waves. Given that only 5% of the universe is detectable by telescopes, the impact of gravitational wave detections on our understanding of the universe is inestimable. Australian partnership intends to enable our physicists and astronomers to be at the vanguard of this brand new field and inspire a new generation to study the physical sciences.Read moreRead less

Summary
Superior performance optical coatings for next-generation interferometry. This project aims to investigate fundamental noise in optical coatings, a limiting factor for state-of-the-art astronomical observatories, global timing standards, and photonics applications. Gravitational wave detectors, marvels of precision engineering that have produced ground-breaking discoveries in fundamental science, are particularly afflicted by coating noise.

This project aims to investigate fundamental noise in optical coatings, a limiting factor for state-of-the-art astronomical observatories, global timing standards, and photonics applications. Gravitational wave detectors, marvels of precision engineering that have produced ground-breaking discoveries in fundamental science, are particularly afflicted by coating noise. The proposed experiment plans to operate at cryogenic temperatures with unprecedented sensitivity to conduct feasibility studies of deposition methods, coating materials, and layer structures. The goal is to deploy innovative methods to develop Australian-made optical coatings with superior performance and merit for the most demanding scientific and industrial applications.Read moreRead less
