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.

More than 100 researchers and students from South Africa and around the world are meeting this week to share plans to use the MeerKAT radio telescope. The MeerKAT Science Workshop will be held at the Stellenbosch Institute for Advanced Study facility on 25-27 May 2016. As the conferen
This year the Nobel Laureate Meeting will take place in Lindau, Germany with one of our esteemed department members to be in attendance. Siyambonga Matshawule has been selected to attend the prestigious meeting. Its aim is to give STEM academics at undergraduate, postgraduate and post
Deep radio imaging by researchers in the University of Cape Town and the University of the Western Cape has revealed that supermassive black holes in 64 galaxies are all spinning out radio jets in the same direction – most likely a result of primordial mass fluctuations in the early u
