Virtual Star Clusters: The Dynamics and Evolution of Stars and Planets. Most stars are born in star clusters. When stars age
they swell and contract, change composition,
lose mass, and in dense regions they may collide.
Further, about 50% of stars are binary pairs,
and when these swell they can merge or
transfer mass. These effects dramatically
alter the lives of stars and their chemical makeup.
By combining special
purpose computers with newly developed simulation techniques,

and when these swell they can merge or

alter the lives of stars and their chemical makeup.
By combining special
purpose computers with newly developed simulation techniques,
we will include all these effects to answer timely
and important astronomical
questions such as: can planets survive life in
a cluster? how do interactions between stars
affect the chemical enrichment of
clusters and galaxies?Read moreRead less
The role of magnetic fields in star formation. Recently we have performed the world's first calculations of star cluster formation that incorporate the effects of magnetic fields and radiation. This research has recently been brought back to Australia and the goal of this proposal is to extend our competitive edge in this area.

This research has recently been brought back to Australia and the goal of this proposal is to extend our competitive edge in this area.
Whilst calculations of the formation of stars gives us fundamental understanding about a very basic physical process in the universe (namely, the conversion of gas into stars), the equations we solve and the methods used to solve them, are the same as those used to describe many gases and fluids on earth. Solving these equations in difficult astrophysical regimes develops new methodology which translates readily to earth-bound problems.Read moreRead less
The next generation of stellar models: incorporating the results of multidimensional hydrodynamics. This project involves the use of computer codes designed for massively-parallel computing, thousands of computers tied together into one cluster, to tackle difficult hydrodynamic problems that occur in stars. We will train PhD students in this area of cutting-edge computation, with applications in areas such as meteorology, aero-space and defence.

Super-AGB Stars: the Missing Link? By being the first to investigate a specific class of stars, Australia will also be the first to reap the scientific rewards from the many applications that will follow - including the chemical history of
the Galaxy and how globular clusters form. We will also develop large-scale computing tools using the latest in cluster computing technology to study the multi-dimensional character of a special class
of supernova explosion. We extend a fruitful collaboratio ....Super-AGB Stars: the Missing Link?

Summary
High Performance Computing Infrastructure Upgrade. The aim of the High Performance Computing Facility is to operate a world class facility as measured by both computational power and client satisfaction. This proposal seeks to increase the current computational power of the existing Victorian High Performance Compting Facility by doubling the current capacity.

The aim of the High Performance Computing Facility is to operate a world class facility as measured by both computational power and client satisfaction. This proposal seeks to increase the current computational power of the existing Victorian High Performance Compting Facility by doubling the current capacity. The combination of a large number of very fast processors and a very fast interconnect makes this facility ideal for modelling and solving science and engineering problems beyond the scope of installed HPC systems. The facility will be linked to other HPC systems in Victoria and across Australia to create an evolving cluster computing "meta-centre" that links computing resources together.

Formation of Supermassive Black Holes. One of the most remarkable discoveries in astronomy is the observation that supermassive black holes, weighing as much as a billion suns, are found in the centers of galaxies, including our own Milky Way. Astronomers do not understand how these black holes came to be, or their role in the evolution of galaxies. This Discovery Project will address these issues by analysing data on supermassive black holes from the local and early universes. Black holes fasci ....Formation of Supermassive Black Holes.

Astronomers do not understand how these black holes came to be, or their role in the evolution of galaxies. This Discovery Project will address these issues by analysing data on supermassive black holes from the local and early universes. Black holes fascinate students both young and old. This Discovery Project will train a new generation of young Australian astronomers at the leading edge of astrophysics.

The High Time Resolution Radio Universe. The radio sky is blanketed by charged particles in the interstellar medium that smear impulsive emissions. By constructing a new digital electronic device for the giant Parkes radio telescope we will be able to divide the radio sky up into many thousands of radio "channels", which when searched on a supercomputer, will enable us to peer into the heart of our Galaxy in search of short bursts of emission. This will be the first large-scale search of the Uni ....The High Time Resolution Radio Universe.

This will be the first large-scale search of the Universe for short bursts of radio emission. The project will pioneer real-time processing of data on a remote supercomputer via a dedicated fibre link. Read moreRead less
Near-field Cosmology with Globular Clusters. Globular star clusters are the astronomical equivalent of fossils, and as such they provide unique insight into the early epochs of the Universe. This project will establish a link between two world-leading research groups in this area. This Australian-Canadian collaboration will train the next generation of PhD students, create innovative 3D visualisation applications and produce a book on globular clusters.
Formation and Evolution in the Extragalactic Universe. Understanding the formation and evolution of galaxies, quasars and clusters of galaxies remains one of the key challenges in modern cosmology.
