The architecture of networks: Characterisation and visualisation of complex systems as fluctuating networks. Complex systems comprise many mutually interacting components, characterised by a range of different interactions over time and space. They are dynamical systems, whose features are reminiscent of a web, with fluctuating links of varying strengths. The natural paradigm for such systems is a generic network, or a graph. A suite of novel measures from statistical physics, graph theory, top ....The architecture of networks: Characterisation and visualisation of complex systems as fluctuating networks. Complex systems comprise many mutually interacting components, characterised by a range of different interactions over time and space. They are dynamical systems, whose features are reminiscent of a web, with fluctuating links of varying strengths. The natural paradigm for such systems is a generic network, or a graph. A suite of novel measures from statistical physics, graph theory, topology, geometry, and computer graphics will be developed to characterise system/graph growth and stability. The aim is two-fold: first to reduce real complex systems (mainly financial systems) to computationally manageable structures (including direct visualisation) and second to construct realistic models of the evolution of such systems.Read moreRead less
The Evolution of Dwarf Elliptical Galaxies: Nature or Nurture? From observations obtained at world-class facilities such as Gemini, this international team of experts will determine whether it is the intrinsic properties of dwarf Ellipticals (nature), or the influence of a neighbouring large galaxy (nurture), that determines the history of star formation in these small galaxies. Studies of local examples of this galaxy type, which may be the first objects formed in the Universe, have shown an u ....The Evolution of Dwarf Elliptical Galaxies: Nature or Nurture? From observations obtained at world-class facilities such as Gemini, this international team of experts will determine whether it is the intrinsic properties of dwarf Ellipticals (nature), or the influence of a neighbouring large galaxy (nurture), that determines the history of star formation in these small galaxies. Studies of local examples of this galaxy type, which may be the first objects formed in the Universe, have shown an unexpected and unexplained diversity of star formation histories. The outcomes of this research are relevant to the evolution of stars, the evolution of the chemical elements, and to the formation of larger galaxies.Read moreRead less
The 6dF Galaxy Survey - Mass and Motions in the Nearby Universe. The 6dF Galaxy Survey will yield by far the largest and most detailed map of the positions and motions of galaxies in the nearby universe. The goal of the survey is to determine the distributions of both the galaxies and the dark matter in order to measure fundamental cosmological parameters and constrain models of galaxy formation. The survey will cover the whole southern hemisphere, measuring redshifts for 120,000 galaxies and di ....The 6dF Galaxy Survey - Mass and Motions in the Nearby Universe.

The survey will cover the whole southern hemisphere, measuring redshifts for 120,000 galaxies and distances and motions for 15,000 galaxies. The survey will use the unique 6dF robotic fibre spectrograph we have constructed for the Anglo-Australian Observatory's Schmidt Telescope.Read moreRead less
A study of vocal tract resonances in the singing voice to develop tools for teaching singing. The voice is our oldest and most widely used musical instrument, but it is incompletely understood because of the difficulty of studying the vocal tract precisely during singing. We shall determine the main techniques used by singers to control and to adapt the acoustic resonances of their vocal tracts. This advance in understanding will enhance Australia's scientific reputation in an area of wide publi ....A study of vocal tract resonances in the singing voice to develop tools for teaching singing. The voice is our oldest and most widely used musical instrument, but it is incompletely understood because of the difficulty of studying the vocal tract precisely during singing. We shall determine the main techniques used by singers to control and to adapt the acoustic resonances of their vocal tracts. This advance in understanding will enhance Australia's scientific reputation in an area of wide public interest. Further, when combined with developments of our novel techniques to operate in real time, it will provide a new tool for students of singing to adjust their resonances and prevent damage to the vocal tract. We shall publish our work not only in the top scientific journals, but also on our popular, multi-award winning web site.Read moreRead less

Discovering the First Generation of Stars in the Galaxy - The Most Metal-Poor Stars. The most metal-poor stars carry a fossil record of the early chemical and dynamical evolution of the Galaxy. The most interesting objects are those with the lowest metal abundances representing the earliest generation of stars in the Galaxy.

The most metal-poor stars carry a fossil record of the early chemical and dynamical evolution of the Galaxy. The most interesting objects are those with the lowest metal abundances representing the earliest generation of stars in the Galaxy. The aim of the present project is to extend the mining of the HES objective spectra to identify extremely metal-deficient giants, which together with the already identified dwarfs will be further distilled using 6dF and the DBS. We anticipate trebling the total number of the most metal deficient stars known and targeting these for observations with 8m telescopes.Read moreRead less

Novel Fermion Actions for Lattice Gauge Theory. The Standard Model of the universe is founded on quantum field theories in which gauge bosons mediate the forces between fermions, the constituents of matter. For example, the gluon of Quantum Chromodynamics (QCD) mediates the strong interactions between quarks as they compose protons, and neutrons. The only way to reveal the long-distance properties of this fundamental gauge theory from first principles is to numerically simulate the theory on a s ....Novel Fermion Actions for Lattice Gauge Theory. The Standard Model of the universe is founded on quantum field theories in which gauge bosons mediate the forces between fermions, the constituents of matter. For example, the gluon of Quantum Chromodynamics (QCD) mediates the strong interactions between quarks as they compose protons, and neutrons. The only way to reveal the long-distance properties of this fundamental gauge theory from first principles is to numerically simulate the theory on a space-time lattice. Simulating fermions on a lattice has proved very challenging. This project will explore novel and innovative improved fermion algorithms for the general problem of gauge theories on the lattice.Read moreRead less
