The Dawn of Extreme Gamma Ray Astronomy. This project aims to reveal the highest energy cosmic-ray particles in our galaxy, produced in extreme and still unknown astrophysical processes. Their interaction with nuclei in space produces the highest energy gamma ray light.

Their interaction with nuclei in space produces the highest energy gamma ray light. Our project will make use of this extreme gamma ray light with upgraded and next-generation gamma-ray telescope arrays. With accompanying data from Australian radio telescopes, and computer models of the cosmic ray interactions, our project can finally determine from where these cosmic rays originate, yielding insight into our galaxy's evolution. Complex machine learning methods will be needed in a project that provides a world-leading student training ground, motivated by a century old mystery in astronomy.Read moreRead less

This project aims to use a new X-ray telescope to find the most disruptive stellar-mass and supermassive black holes in the Universe, and characterise their outflows with some of the world's most sensitive radio telescopes. This research will answer fundamental questions identified by the astronomical community regarding how black holes grow, how they generate powerful outflows, and how much energy they can deposit into the surrounding environment. It will forge strong links with international partners, strengthen Australian expertise in this high-impact area of science, and stimulate public outreach work.Read moreRead less

This project aims to harness the capabilities of the upgraded Pierre Auger Observatory to identify sources of the highest energy cosmic rays, the most energetic particles known in the Universe. Their origin is one of the longest standing mysteries in astrophysics, but answers are now within reach. Expected outcomes of the project include mass estimates for every measured cosmic ray, and sky maps of cosmic ray arrival directions that take into account the cosmic ray charge, minimising the effects of path deflections by cosmic magnetic fields. These maps will reveal new information on the types of astrophysical objects capable of accelerating particles to extreme energies, a major step towards solving this difficult problem.Read moreRead less
Cosmic powerhouses: The birth, death, and legacy of black hole jets. This project targets relativistic jets powered by supermassive black holes - the most powerful systems in the Universe. Theoretically, the enormous energies released have a profound influence on how galaxies evolve; empirically, observations reveal signatures of their impact across cosmic time. However, fundamental questions remain about how these jets are triggered and what impact they have on galaxies.

This project targets relativistic jets powered by supermassive black holes - the most powerful systems in the Universe. Theoretically, the enormous energies released have a profound influence on how galaxies evolve; empirically, observations reveal signatures of their impact across cosmic time. However, fundamental questions remain about how these jets are triggered and what impact they have on galaxies. The project will address these questions using novel supercomputer models of black hole jets in realistic cosmological environments, then confront these predictions with new data from Square Kilometre Array (SKA) pathfinding radio telescopes. This will substantially enhance Australia’s leadership capacity in a strategically important area.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.

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
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.

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
