Prof. Catherine Cress (UWC)

I will give an overview of CHPC facilities and astronomy-related work underway here. I will present a number of projects related to clusters of galaxies, including: (a) the clustering of Planck clusters as a probe of their mass (providing insight into apparent problems with Planck data); (b) SALT follow-up of clusters detected by the Atacama Cosmology Telescope; (c) radio observations of halos and star-forming galaxies in clusters and (d) probing the expansion rate of the universe using the luminous red galaxies typically found in clusters. I will also discuss simulation work aimed at modelling the radio sky, including the neutral hydrogen and continuum emission that will be detected by the MeerKAT/SKA.
