The diversity of core-collapse supernovae. This project aims to develop a comprehensive picture of the explosions of massive stars as core-collapse supernovae using high-end computer simulations. Such explosions come in many varieties and arise from different classes of progenitor stars. This project seeks to thoroughly understand this diversity.

This project aims to develop a comprehensive picture of the explosions of massive stars as core-collapse supernovae using high-end computer simulations. Such explosions come in many varieties and arise from different classes of progenitor stars. This project seeks to thoroughly understand this diversity. It endeavours to provide simulations of supernovae powered by magnetic fields, supernovae that produce black holes, supernovae in binary systems, and the most energetic neutrino-driven supernovae. The project also aspires to better link numerical simulations, observations of supernovae and their remnants, and the nucleosynthesis fingerprints that supernovae have left in the chemical history record of galaxies.Read moreRead less

Summary
Before stars go supernova - in 3D. This project aims to understand the full three-dimensional structure of massive stars when they explode. In particular, the project will model the late evolution and burning stages of massive stars before they explode as core collapse supernovae. The violent nature of the thermonuclear burning during the star's last few minutes and seconds may cause significant deviations from spherical symmetry, in particular when considering rotating stars. Such realistic mod ....Before stars go supernova - in 3D. This project aims to understand the full three-dimensional structure of massive stars when they explode. In particular, the project will model the late evolution and burning stages of massive stars before they explode as core collapse supernovae. The violent nature of the thermonuclear burning during the star's last few minutes and seconds may cause significant deviations from spherical symmetry, in particular when considering rotating stars. Such realistic models are an essential ingredient for any realistic supernova model, and for understanding how these supernovae synthesise the entire range of elements (from lightest to the heaviest) in the universe.Read moreRead less

This project aims to perform simulations of core-collapse supernovae, the explosive death of massive stars, to better understand their explosion properties, remnant properties, and gravitational wave emission. This project expects to produce gravitational wave emission predictions in previously unexplored areas of the supernova progenitor parameter space. The expected outcomes of this project include novel gravitational wave data analysis tools, and a better understanding of the birth properties of neutron stars and black holes. This should provide significant benefits, such as improving our understanding of the astrophysics behind core-collapse supernovae, and improving our understanding of neutron star and black hole populations.Read moreRead less

Discovering the most extreme pulsars with the next generation radio surveys. Finding radio pulsars has always been an extremely rewarding challenge and has led to Nobel Prize winning science. We are now entering a new era of radio astronomy and have new game changers, sensitive, wide-field-of-view imaging telescopes and massive compute resources, to search for extreme pulsars. Such pulsars, including pulsar-blackhole systems and sub-millisecond pulsars, cannot be found with traditional pulsar su ....Discovering the most extreme pulsars with the next generation radio surveys. Finding radio pulsars has always been an extremely rewarding challenge and has led to Nobel Prize winning science. We are now entering a new era of radio astronomy and have new game changers, sensitive, wide-field-of-view imaging telescopes and massive compute resources, to search for extreme pulsars. Such pulsars, including pulsar-blackhole systems and sub-millisecond pulsars, cannot be found with traditional pulsar surveys, but provide us unique laboratories to test gravity theories at ultra-strong gravitational fields and probe the state of matter at supra-nuclear densities. In this project I will leverage the Australian Square Kilometre Array Pathfinder (ASKAP) to discover the most extreme pulsars in deep all-sky continuum surveys.Read moreRead less

An ultra-wideband radio receiver for the Parkes 64-metre radio telescope: This project aims to construct a state-of-the-art ultra-wide-band receiver and signal processing system for the Parkes 64-metre radio telescope. The receiver will operate across the entire 700 megahertz to four gigahertz band with outstanding sensitivity and polarimetric performance, providing a unique capability for high-time-resolution wide-bandwidth astronomy. It is expected to deliver enhanced science outcomes for a wide range of projects and greatly improve the telescope's operational efficiency, extending its lifetime into the Square Kilometre Array era. Key science projects include tests of theories of relativistic gravitation, including the search for gravitational waves, probing neutron star interiors and investigations of the magnetic structure of our galaxy.Read moreRead less
