Feedback Processes in Galaxy Formation. We have an opportunity to combine the best Australian theory with the best local and international telescopes, to probe the murky story of how galaxies form and why they look they way they do today. By looking back to a time when the Universe was only 1 billion years old, and comparing what we see with cutting edge supercomputer simulations plus pure theory, we will gain insight into the birth of entire galaxies. The results will form part of the study o ....Feedback Processes in Galaxy Formation. We have an opportunity to combine the best Australian theory with the best local and international telescopes, to probe the murky story of how galaxies form and why they look they way they do today. By looking back to a time when the Universe was only 1 billion years old, and comparing what we see with cutting edge supercomputer simulations plus pure theory, we will gain insight into the birth of entire galaxies. The results will form part of the study of how the universe works - that is driving astrophysics today, and represents pure research for the sake of advancing knowledge and showing us where we fit into the Universe. In doing so we will also advance Australia's base of theoretical and computational expertise.Read moreRead less
Using high-resolution lasers to test quantum electrodynamics. High-precision laser-based measurements of atomic and molecular structure are benchmarks for our fundamental understanding of matter. This project will undertake state-of-the-art experiments on atomic helium, to test and challenge current theoretical predictions of fundamental quantum-electrodynamic properties for helium and for more complex atoms.
Auger-electron yields of medical radioisotopes. Large numbers of Auger electrons are emitted during the decay of many medical isotopes. Auger electrons have a short range and a strong ability to break chemical bonds. However no measurements of the number of Auger electrons per nuclear decay exist in the critical low energy regime. Calculated Auger yields are incomplete and inconsistent. Building on unique Australian expertise and instrumentation, and performing both calculations and measurements ....Auger-electron yields of medical radioisotopes. Large numbers of Auger electrons are emitted during the decay of many medical isotopes. Auger electrons have a short range and a strong ability to break chemical bonds. However no measurements of the number of Auger electrons per nuclear decay exist in the critical low energy regime. Calculated Auger yields are incomplete and inconsistent. Building on unique Australian expertise and instrumentation, and performing both calculations and measurements, his project aims to determine the number of Auger electrons per nuclear decay accurately for medical isotopes. The outcome will be accurate dose data for radioisotopes, plus essential knowledge to develop new cancer treatments based on Auger electrons, which target a fraction of a cell.Read moreRead less
