The University of Cape Town Cosmology and Gravity Group is now the largest group of its kind in the southern hemisphere. We bring together a diverse range of expertise and have strong links with UCT’s Department of Astronomy and the South African Astronomical Observatory. In addition the number of international collaborations has grown, largely as a result of bilateral agreements signed with other countries. The research themes of the Cosmology group include among other things: early universe physics, string theory and cosmology, non-linear problems in astrophysics and cosmology, modelling inhomogeneity, gravitational wave physics and observational cosmology.
