Neutrinos are very weakly interacting elementary particles that are opening a new view on astrophysical objects such as supernovae and active galactic nuclei (neutrino astronomy).

Neutrinos are very weakly interacting elementary particles that are opening a new view on astrophysical objects such as supernovae and active galactic nuclei (neutrino astronomy). Studies of astrophysical neutrino production, propagation and terrestrial detection will be made. This will shed light on the astrophysics of the sources as well as probing propagation effects such as neutrino oscillations. A distinct programme will study a large discrepancy in the energy balance for matter accreting into a black hole. Previous work of Buzzi and Hines will be extended to investigate whether plasma wave energy carried into the black hole can explain the discrepancy. Read moreRead less
Nucleosynthesis of low and intermediate mass stars: A study into the origin of the elements. Everything in our Solar System, including the Sun and all life on Earth, were created out of material forged long ago in fiery stellar furnaces. In the hot dense cores of long dead stars the material most vital to life was created. However, the stellar origin of many elements is unknown although we can make guesses, from observations of stars and by bringing together ideas from different scientific fiel ....Nucleosynthesis of low and intermediate mass stars: A study into the origin of the elements. Everything in our Solar System, including the Sun and all life on Earth, were created out of material forged long ago in fiery stellar furnaces. In the hot dense cores of long dead stars the material most vital to life was created. However, the stellar origin of many elements is unknown although we can make guesses, from observations of stars and by bringing together ideas from different scientific fields including astrophysics, nuclear physics and geochemistry. Using the latest theoretical techniques together with the most recent experimental data, it is possible to piece together the clues
to unravel the mystery of the origin of the elements.

The Early History of Dark Energy. The national benefit will be the inclusion of Australian researchers (Glazebrook and his students/postdocs) in a major UK-Japanese international research project to study dark energy. This will be the successor to the highly successful WiggleZ project (on which Glazebrook is a designer and CI) using the much larger mirror of Subaru to push back the mapping of cosmic sound to much earlier epochs in the history of the Universe. Although Australia built parts of th ....The Early History of Dark Energy. The national benefit will be the inclusion of Australian researchers (Glazebrook and his students/postdocs) in a major UK-Japanese international research project to study dark energy. This will be the successor to the highly successful WiggleZ project (on which Glazebrook is a designer and CI) using the much larger mirror of Subaru to push back the mapping of cosmic sound to much earlier epochs in the history of the Universe. Although Australia built parts of the FMOS instrument (under contract) there is currently no national right of access to any of the science surveys so it is only by developing these collaborations that we can capitalize on our innovative instrument design.Read moreRead less
Gravitational wave astrophysics with Laser Interferometer Gravitational-Wave Observatory (LIGO). The prediction that space and time vibrate is one of Einstein's greatest legacies, implying the existence of a new form of radiation with which to study the Universe. This project puts Australia in the vanguard of the billion-dollar effort worldwide to detect and harness this radiation for the first time.
High-energy probes of dense matter and distorted spacetime. This is an ambitious but achievable program with the potential for results which will be highly significant to physicists worldwide. The expected outcomes have the potential to alter our understanding of fundamental physics, and will demonstrate that Australia's high-energy research ability is on par with the world's best.

The techniques of X-ray astronomy are increasingly a standard part of the professional astronomer's toolkit, although Australia has a limited track record in recent years. The international collaborations that this project will build and maintain will help to improve access to, and utilisation of, multi-million dollar international satellite observatories by local observers.Read moreRead less

The techniques of X-ray astronomy are increasingly a standard part of the professional astronomer's toolkit, although Australia has a limited track record in recent years. This DP will boost the multiwavelength capability of local astronomers by attracting a talented postdoc with experience in X-ray astronomy to Australia, as well as supporting a broader effort to transfer such skills to local students and researchers.Read moreRead less
The origin and evolution of heavy elements in the early universe. Everything in our Solar System, including all life on Earth, was created long ago out of material forged inside fiery stellar furnaces. The latest theoretical simulations of element production in red giant stars reveals the processes that gave us our existence, as well as help us to understand the origin of the galaxy that we inhabit.

Summary
Modelling superfluid neutron stars. This project aims to construct realistic neutron star models, that will be used to interpret radio and x-ray data, but also to aid gravitational wave detection. These models will allow the study of matter at extreme densities in the stellar interior, well above nuclear density, thus making use of the most exciting physics laboratory in the cosmos.
Modelling the chemical enrichment of the Milky Way. This project aims to understand the chemical and dynamical evolution of the Milky Way Galaxy from its birth to the present. Astrophysicists try to understand the production of the elements over cosmic time, using telescopes and satellites costing billions of dollars. This project will calculate the evolutionary history and detailed nuclear processes in stars of all masses and compositions. When coupled with dynamical models for stars in the Mil ....Modelling the chemical enrichment of the Milky Way. This project aims to understand the chemical and dynamical evolution of the Milky Way Galaxy from its birth to the present. Astrophysicists try to understand the production of the elements over cosmic time, using telescopes and satellites costing billions of dollars. This project will calculate the evolutionary history and detailed nuclear processes in stars of all masses and compositions. When coupled with dynamical models for stars in the Milky Way, this project will categorise how the composition changes with time, thus extracting the maximum understanding from the wealth of data to be delivered in the next few years.Read moreRead less
The origin of the elements heavier than iron. This research investigates the cosmic origin of the elements heavier than iron, as they are produced by nuclear reactions inside stars. The study of these elements in stars and meteorites will help us to understand the origin and history of the Solar System, of old stars and of stellar clusters and galaxies.
