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 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

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

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

Solving the mystery of ultra luminous fast radio burst emission . Fast Radio Bursts are a recently discovered inexplicable astronomical phenomenon whose millisecond-timescale emission is generated by regions less than 300 kilometres across yet so luminous it is visible at cosmological distances. Using the Australian Square Kilometre Array Pathfinder we have already localised these bursts, which made the front cover of Science, and recently used them to find the missing baryonic matter in the Uni ....Solving the mystery of ultra luminous fast radio burst emission . Fast Radio Bursts are a recently discovered inexplicable astronomical phenomenon whose millisecond-timescale emission is generated by regions less than 300 kilometres across yet so luminous it is visible at cosmological distances. Using the Australian Square Kilometre Array Pathfinder we have already localised these bursts, which made the front cover of Science, and recently used them to find the missing baryonic matter in the Universe. Next, we will scrutinise these bursts at three nanosecond time resolution, reaching the timescale necessary to probe the mechanism by which their ultra-luminous radiation is generated. This project will reveal previously inaccessible properties of the radiation to unlock the secrets of how they are produced.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.

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

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
