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.

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
The Big Bang is often considered the starting point of our universe, but two researchers have proposed an idea that does not point at Big Bang as the event that catapulted the formation of the cosmos. Saurya Das from the University of Lethbridge in Canada and Ahmed Farag Ali from Egy
Group coffee is at 10.30. Journal Club will feature one main paper each week with a 5/10 minute discussion. Other papers of interest are highlighted using our citeulike group (UWC Astro). Please highlight any relevant papers by 10.30 on Monday morning to ensure that they can be downloaded in time. All students are expected to highlight at least one paper of interest each week. If you are not a member of the group then please talk to one of the postdocs or register here. Click here for the Journal Club Schedule.
