Summary
How galactic mergers and their stellar survivors shaped our Milky Way. This project aims to investigate the role of mergers with smaller galaxies in shaping the Milky Way by developing tools to identify stellar survivors of mergers. This project expects to produce an all-sky map of stellar survivors based on the largest search within Australian and international survey data and perform innovative comparisons with simulations to constrain the role of mergers.

This project aims to investigate the role of mergers with smaller galaxies in shaping the Milky Way by developing tools to identify stellar survivors of mergers. This project expects to produce an all-sky map of stellar survivors based on the largest search within Australian and international survey data and perform innovative comparisons with simulations to constrain the role of mergers. Expected outcomes are aligned with the decadal plan for Australian astronomy and can open new avenues for global astronomy and contracts for upcoming billion-dollar surveys. The project should cement Australia’s role as a leader in a new era of galactic exploration and provide benefits beyond astronomy by training Australians to assess complex big data.Read moreRead less

This Discovery Project aims exploit the next generation spectroscopy with the James Webb Space Telescope, combined with Australian supercomputing expertise to make fundamental new measurements of the formation of stars in the first galaxies. The results will be used to make predictions for key experiments that will be conducted with the Square Kilometer Array. The research outcomes aim to benefit astronomy by generating new knowledge of high redshift galaxies and provide new spectral star-formation diagnostics which will be made available to the general astronomical community. The project also aims to provide cultural benefit through effective public and education as well training of future leaders for astronomy and industry research.Read moreRead less

This will generate critical discoveries that cement Australia's leadership role in the gravitational wave mega-science instruments of the 2030s and 2040s. By bringing together a world-class team with broad and complementary expertise we will develop core technologies for future detectors, discover new sources of gravitational waves, probe fundamental physics, and lay the foundations for an Australian gravitational wave observatory. Our discoveries will inspire Australia's youth to pursue high tech careers and position our staff and students to become leaders in both industry and academia.Read moreRead less
Star Formation Through Cosmic Time. This project aims to determine how turbulence and magnetic fields control the formation of stars. This is crucial to understand the formation of galaxies, planets and ultimately life. The expected outcomes are the most detailed simulations of star formation in the early Universe and in galaxies today. This project has the potential to transform our understanding of cosmic structure formation, providing crucial input for Australian and international facilities ....Star Formation Through Cosmic Time. This project aims to determine how turbulence and magnetic fields control the formation of stars. This is crucial to understand the formation of galaxies, planets and ultimately life. The expected outcomes are the most detailed simulations of star formation in the early Universe and in galaxies today. This project has the potential to transform our understanding of cosmic structure formation, providing crucial input for Australian and international facilities and surveys, and models of galaxy, star and planet formation. Training Australia's future generation of Big Data analysts, as well as the development of interdisciplinary tools involving Chemical Modelling, Plasma Physics, Statistics and High Performance Computing are key benefits.Read moreRead less
Relativistic Particles in Star-Forming Galaxies. This project aims to understand how galactic evolution is shaped by the relativistic particles known as cosmic rays that fill interstellar space. We understand only poorly how cosmic rays interact with non-relativistic interstellar matter, which in turn limits our understanding of how they affect galaxies. The project seeks to resolve this question by calculating how cosmic ray-matter interaction gives rise to light and neutrinos that we can obser ....Relativistic Particles in Star-Forming Galaxies. This project aims to understand how galactic evolution is shaped by the relativistic particles known as cosmic rays that fill interstellar space. We understand only poorly how cosmic rays interact with non-relativistic interstellar matter, which in turn limits our understanding of how they affect galaxies. The project seeks to resolve this question by calculating how cosmic ray-matter interaction gives rise to light and neutrinos that we can observe using current and future telescopes, enabling us to use observations from these telescopes to solve the problem of cosmic ray-matter interaction. This would resolve the question of how cosmic rays shape galaxy evolution, and thus represent a substantial advance in the theory of galaxy formation.Read moreRead less

Unveiling the Winds of Star-Forming Galaxies. This project seeks to resolve an outstanding problem in the formation of cosmic structure: what is the nature of galactic winds, and what physical mechanisms are responsible for driving them? Answering these questions requires computer simulations of greater resolution than have previously been possible, coupled to next-generation telescopic observations.

This project seeks to resolve an outstanding problem in the formation of cosmic structure: what is the nature of galactic winds, and what physical mechanisms are responsible for driving them? Answering these questions requires computer simulations of greater resolution than have previously been possible, coupled to next-generation telescopic observations. This research aims to develop novel methods to enable the required simulations, leveraging new hardware architectures at Australian supercomputer facilities, and to use these approaches to solve a major open problem in astrophysics, open new frontiers in simulation, and multiply the return on Australia's investment in both computer facilities and telescopes that will study galactic winds.Read moreRead less

Summary
Synergy between future 21-cm experiments and physical cosmology. The nature of dark matter and formation of the first galaxies are both unsolved mysteries. During the first 500 million years, our universe was filled with hydrogen atoms illuminated by the first galaxies. The 21-cm radiation from this gas encodes properties of unseen galaxies and dark matter during this so-called cosmic dawn.

During the first 500 million years, our universe was filled with hydrogen atoms illuminated by the first galaxies. The 21-cm radiation from this gas encodes properties of unseen galaxies and dark matter during this so-called cosmic dawn. This project aims to build an innovative framework to leverage future 21-cm experiments using The Square Kilometre Array to observe cosmic dawn, and to forecast the optimal constraints on dark matter physics. Additional outcomes include the largest cosmological simulation of the first galaxies powered by neural networks and improved knowledge of their properties using Bayes' theorem and The James Webb Space Telescope.Read moreRead less
