Characterising distant galaxies by way of spectral energy distribution analysis

The analysis of galaxies found throughout cosmic time provides us with the means to probe the underlying characteristics of the known universe.Over the last few decades, new observations of galaxies with various ground and space-based telescopes have provided us with an abundance of multi-wavelength data.By coupling these observations with theory, spectral energy distribution analysis allows us to derive the intrinsic properties of distant galaxies, which provides constraints for various galaxy formation and evolution scenarios.During this project, you will have access …

The cosmic star formation history measured from Evolutionary Map of the Universe (EMU) data

The cosmic star formation history (SFH) describes how the rate of star formation in the universe has evolved. This has been measured with increasing precision in recent decades. Using highly sensitive radio detections, this cosmic star formation history can be determined to the highest level of precision yet.The Evolutionary Map of the Universe (EMU) radio survey will measure up to 30 million radio sources in the coming few years. We estimate half of these will arise from star formations.Using the …

The evolution of dust obscuration in galaxies

Dust in galaxies is ubiquitous. It arises from the end stages of stellar evolution, with heavy elements formed over a star's lifetime being distributed throughout a parent galaxy as the star goes supernova.There are numerous approaches to measuring dust obscuration in galaxies. These approaches show a broad trend toward heavier obscuration in galaxies that support higher levels of star formation. However, there is relatively little understanding for why this relationship exists.By analysing the properties of galaxies in the Galaxy And …
