Neutral hydrogen and galaxy assembly in the distant Universe. This research will produce a snapshot of hydrogen gas in the Universe 6-7 billion years ago. These results, together with galaxy formation models, will tell us how galaxies are assembled to make the beautiful spirals we see today. This project is only possible because of rapid advances in programmable chip technology, part of the massive increase in the speed and complexity of integrated circuit devices.
Our Galaxy: the last hundred million years. Star formation and evolution are the fundamental processes which energize a galaxy and recycle the interstellar medium. In our Galaxy, we have the opportunity to study these processes in great detail. This project uses sensitive radio continuum images from the Molonglo Observatory Synthesis Telescope to discover how this energizing and enrichment occurs. We will use innovative machine learning techniques to identify a potentially new population of Gala ....Our Galaxy: the last hundred million years.

In our Galaxy, we have the opportunity to study these processes in great detail. This project uses sensitive radio continuum images from the Molonglo Observatory Synthesis Telescope to discover how this energizing and enrichment occurs. We will use innovative machine learning techniques to identify a potentially new population of Galactic sources and to patrol a new domain in source variability.Read moreRead less

The laser sources generally do not have simple (Gaussian) distributions. The applicant has recently developed a model, describing free propagation of complex (non-Gaussian) laser beams. This project seeks to develop a comprehending model for laser beams propagation through complex optical systems. The effects of various optical elements will be defined employing a novel method known as SAFE (Stable Aggregate of Flexible Elements) which is a compromise between geometrical and physical optics. Applying this model to micromachining and optical data storage (ODS), which need high beam quality (low divergence and good focussibility), enable accurate predictive capability critical to the optimisation of micromachining and ODS designs.Read moreRead less
