Analysis of large scale structure in the Universe using 6dF and ASKAP simulations


I am using large scale analysis methods, like the correlation function and power spectrum, to determine cosmological parameters and testing galaxy formation models. I am applying these methods to the 6dF Galaxy redshift survey, which is one of the largest redshift surveys to date. This kind of analysis will tell us something about the properties of our Universe like the dark matter content or the time scale of structure formation. My work includes test of dark matter halo models and comparison to N-body simulations. The experience with the 6dF survey in the first part of my PhD will be used to make predictions for surveys like the WALLABY survey. This survey will be conducted at the Australian SKA Pathfinder telescope (ASKAP) in Western Australia. It will be the by far largest HI survey and a fantastic sample to study galaxy formation. I am working together with the 6dF group at the Anglo-Australien Observatory in Sydney and with Chris Blake at Swinburn University in Melbourne.

Why my research is important

The cosmological parameters of the Universe are still uncertain. Although dark matter is now widely accepted (40 years after the discovery) it is still not clear what it actually is. The discovery of dark energy is only 10 years ago and provides an even bigger puzzle for astronomers. The 6dF survey will be able to constrain existing cosmological models and will provide us with a unique view of our Universe. The formation of Galaxies is the fundamental structure formation process in the Universe and is still poorly understood. Studies of clustering properties and halo models can lead the way to a better understanding. Since the ASKAP telescope is one of the largest science projects in Australia, detailed simulations for the surveys are necessary to maximize the outcome for the astronomical community. These simulations will be used to make predictions based on the current cosmological models.
