We run high resolution hydrodynamical simulations to investigate the dynamics of gas in clusters of galaxies and the intergalactic medium.
Galaxy Cluster Surveys
Searching for and characterising clusters of galaxies - the most massive objects in the Universe.
Exploring the cosmological perturbations that lead to the large-scale structure, gravitational waves and magnetic fields in the Universe.
Resolving pulsation modes in hot sub-dwarf and white dwarfs to model their evolution and internal structure. We are also searching for brown dwarf planetary companions through study of evolved eclipsing binaries and pulsating stars.
Combining large datasets taken at multiple wavelengths, to maximise our understanding of the Universe.

A map like nothing on earth Scientists from around the world have joined forces to lay the foundations for an experiment of truly astronomical proportions: putting together the biggest map of the universe ever made. Scientists from South Africa are playing a key role in determining ho
The Astrophysics Group at the University of the Western Cape, invites applications for two postdoctoral positions in cosmology. The group has grown dramatically in recent years, with 6 faculty members, 17 postdocs and 14 postgrad students. The group is deeply involved in work related
Top scientists the world over are lining up to be part of South Africa’s Square Kilometre Array radio telescope project and the cutting edge in global astronomy. Hidden deep in the Karoo, Carte Blanche gets exclusive access to the site and an unprecedented take on a 650 million euro p
An article in News: South African scientists are playing major roles in laying out plans for the Square Kilometre Array’s (SKA) mammoth surveys of the skies. The SKA will have thousands of satellite dishes in South Africa and Australia with the core of the telescope in the Northern Ca
