The Dark-side of the Milky Way. Astronomers have long sought to determine the 3-dimensional structure of our Galaxy, the Milky Way, with limited success owing to its immense size and obscuration by dust at optical wavelengths. We know more about structure of tens of thousands of other galaxies than we do about the structure of the Milky Way on the far-side of the Galactic Centre. This program will use Australian infrastructure to make the most accurate distance measurements to date of the far-si ....The Dark-side of the Milky Way. Astronomers have long sought to determine the 3-dimensional structure of our Galaxy, the Milky Way, with limited success owing to its immense size and obscuration by dust at optical wavelengths. We know more about structure of tens of thousands of other galaxies than we do about the structure of the Milky Way on the far-side of the Galactic Centre. This program will use Australian infrastructure to make the most accurate distance measurements to date of the far-side of the Milky Way visible from the Southern hemisphere, completing the 3-dimensional picture of our Galaxy. These results will be leveraged to yield accurate distances, providing fundamental information on the stellar masses, luminosities, and ages.Read moreRead less
Utilising artificial intelligence to elucidate the physics of galaxies. For decades astronomers have puzzled over the connection between the structure and evolution of galaxies and the role played by host environments.

For decades astronomers have puzzled over the connection between the structure and evolution of galaxies and the role played by host environments. This project aims to resolve this problem by combining multi-wavelength observations, multi-component simulations, and pioneering data analysis using artificial intelligence. In particular, we target the nearby Fornax galaxy cluster as a laboratory for studying galaxy formation in dense environments. Using our novel machine learning techniques, we will elucidate the physical mechanisms that drive the rapid evolution of star formation, galactic nuclei, and gas and dust content within Fornax. Our predictions will benefit ongoing and future surveys at the national and international level. Read moreRead less

Ultra Diffuse Galaxies: Challenging the galaxy formation paradigm . We aim to understand the origins of newly discovered Ultra Diffuse Galaxies. Their extreme properties challenge many assumptions underpinning the accepted cosmological framework within which galaxies form, especially the role of dark matter and its interaction with normal matter.

We aim to understand the origins of newly discovered Ultra Diffuse Galaxies. Their extreme properties challenge many assumptions underpinning the accepted cosmological framework within which galaxies form, especially the role of dark matter and its interaction with normal matter. Outcomes, enabled by the world’s best telescopes, novel machine learning techniques and supercomputer simulations of galaxy formation, will be a large new sample with measurements of their key properties and a clarification of their formation pathways. Benefits are the development of machine learning galaxy detection techniques, essential for future large data volumes, and a firmer understanding of the role of dark matter in forming galaxies over cosmic time.Read moreRead less
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.

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

This project aims to use chemical approaches to develop molecular transistors, which are critical components for a future molecular electronics technology. The use of molecules as ultra-miniaturised electronic components is gathering attention from industry and academia, as a solution to the approaching limits of top-down scaling. However, current molecular designs based on gating through chemical reaction or redox state changes are slow and inefficient. The project will develop molecular transistors with exceptionally high gain and fast response based on gating the energy of quantum interference features in molecules with cross-conjugated or ring-like shapes. This will provide significant benefits including new strategies for nanofabrication of molecular devices.Read moreRead less
