Research


The department specialises in the study of galactic structure, the distance scale, large-scale structures and evolution of galaxies in the Universe, next to high-speed photometry and spectroscopy of cataclysmic variable stars.

Particular emphasis is given on uncovering galaxies obscured by the Milky Way (the Zone of Avoidance) and the mapping of cosmic flow fields such as in the Great Attractor region. With the opening of SALT (the Southern African Large Telescope), new research areas were initiated in galaxy evolution (as a function of environment and redshift (z ~ 0.15 - 0.6), the dark matter content in nearby dwarf and low surface brightness galaxies, and the search for intermediate mass black holes.

Studies of cataclysmic variable stars and pulsating white dwarfs remain a highly active research area of the department, in which the high speed photometry capabilities of SALT also offers new unique insights in to the physics of these highly interesting objects.
The department is an active participant of the National Astrophysics and Space Science Programme (NASSP) - hosted at UCT - which offers BSc Honours and Masters degrees. The department currently has 26 postgraduate students (10 PhD and 16 MSc students). It has strong links with the South African Astronomical Observatory (SAAO) at only 3.5 km from UCT campus. The department also enjoys active research collaborations with other groups abroad.
RESEARCH FACILITIES



Staff and students in the department have access to a wide range of optical, near-infrared and radio facilities inside and outside of South Africa.
South Africa is home to the largest optical telescope in the world (SALT), and is currently constructing meerKAT (a demonstrator of the Square Kilometer Array technology) in the Karoo desert, consisting of ~80 12-m dishes. At the SAAO site in Sutherland, a 1.4-m near-infrared survey telescope (IRSF) provides complementary near-infrared coverage.
