The fossil record of galaxy formation. This Australian-led team recently used the Anglo-Australian Telescope to discover large numbers of a new type of very small galaxy in the centres of two galaxy clusters. This project will maintain Australian leadership in this new area of astrophysics research, whilst using the best international expertise and facilities.

Galaxy recycling in clusters of galaxies. Large galaxies are thought to form by merging smaller dwarf galaxies, but recent discoveries reveal a more violent picture: some dwarf galaxies are torn apart by the gravity of their companions, their contents strewn across inter-galactic space.
We will investigate how much this debris is recycled into other galaxies. We will examine Hubble Space Telescope images of dwarf galaxies to test if they are broken up to form the ultra-compact dwarf galaxies we ....Galaxy recycling in clusters of galaxies.

We will investigate how much this debris is recycled into other galaxies. We will examine Hubble Space Telescope images of dwarf galaxies to test if they are broken up to form the ultra-compact dwarf galaxies we recently discovered. We will model the rate at which dwarf galaxies are disrupted to determine how the dark matter is distributed in such galaxies.Read moreRead less
Fluctuations in the properties of nonequilibrium fluids and the influence of thermostatting mechanisms. The behaviour of nonequilibrium fluids will be studied by combining ideas from liquid state theory, statistical mechanics and dynamical systems theory. This work will result in development and testing of mathematical expressions (Fluctuation Theorems) that are consistent with the Second Law of Thermodynamics, which determines the direction of any change in any macroscopic system, but are also ....Fluctuations in the properties of nonequilibrium fluids and the influence of thermostatting mechanisms. The behaviour of nonequilibrium fluids will be studied by combining ideas from liquid state theory, statistical mechanics and dynamical systems theory. This work will result in development and testing of mathematical expressions (Fluctuation Theorems) that are consistent with the Second Law of Thermodynamics, which determines the direction of any change in any macroscopic system, but are also applicable to microscopic systems. The expressions will determine the probability that finite sized systems will violate the Second Law for small periods of time and will therefore contribute to development of a fundamental understanding of microscopic systems and the development of nanotechnology.

Modelling of Adsorption Dynamics in Microporous Adsorbents Using Fractional Order Diffusion Equations. This project investigates the use of fractional order diffusion equations in modelling adsorption dynamics in microporous carbons. The long tail behaviour of adsorption processes cannot be readily explained by the classical second order Fickian model, and makes adsorption a candidate for the use of fractional order diffusion equations that have the potential to model such features. In the pre ....Modelling of Adsorption Dynamics in Microporous Adsorbents Using Fractional Order Diffusion Equations. This project investigates the use of fractional order diffusion equations in modelling adsorption dynamics in microporous carbons. The long tail behaviour of adsorption processes cannot be readily explained by the classical second order Fickian model, and makes adsorption a candidate for the use of fractional order diffusion equations that have the potential to model such features. In the present project we shall develop suitable numerical techniques for solving the fractional order diffusion model, and apply these to the interpretation of experimental kinetic data. The outcome will be an improved model of adsorption dynamics considering the fractal nature of the solid.Read moreRead less
Bimolecular chemistry at very low temperatures. Many chemical reactions involve short-lived and highly reactive intermediates that cannot be observed under ordinary reaction conditions. Hence, much of this chemistry is shrouded in mystery. This project aims to develop the ability to observe and monitor such reactions directly using a combination of spectroscopies at very low temperatures, where the molecules are more stable and reactions slower. These studies will give quantitative information ....Bimolecular chemistry at very low temperatures. Many chemical reactions involve short-lived and highly reactive intermediates that cannot be observed under ordinary reaction conditions. Hence, much of this chemistry is shrouded in mystery. This project aims to develop the ability to observe and monitor such reactions directly using a combination of spectroscopies at very low temperatures, where the molecules are more stable and reactions slower. These studies will give quantitative information on the nature of the reactive intermediates themselves, the nature of the products formed, and the reaction dynamics, and they are of fundamental importance for an understanding of chemical reactivity generally. The methodology developed will be applicable to the investigation of a wide range of processes.Read moreRead less

Flows driven by the application of a horizontal temperature gradient has applications in nature and engineering. Although much progress has been made in the analysis of the case of a sudden application of temperature differences to the vertical walls of a container with insulating horizontal walls containing an isothermal fluid, the reality is that neither the insulated walls nor the initially isotherma ....Time dependent stratified flows in a differentially heated cavity under realistic conditions. Flows driven by the application of a horizontal temperature gradient has applications in nature and engineering. Although much progress has been made in the analysis of the case of a sudden application of temperature differences to the vertical walls of a container with insulating horizontal walls containing an isothermal fluid, the reality is that neither the insulated walls nor the initially isothermal fluid can be achieved. This project will, by analytical, numerical and experimental methods, make a preliminary investigation of the influence of conducting horizontal walls and an initially stratified fluid.Read moreRead less
