Prof Davé is the SARChI Chair at the University of Western Cape. He uses high-performance supercomputers to model the formation and evolution of galaxies and intergalactic gas from the Big Bang until today. Galaxies are exceptionally complex systems, hence such models must include the effects of cosmology and large-scale structure growth, accurate hydrodynamics, star formation, black holes, chemical evolution, feedback processes from supernovae and active nuclei, and in some cases radiation transport and magnetic fields.
Moreover, galaxies evolve in a cosmic ecosystem with their surrounding intergalactic gas, exchanging mass and energy in a way that crucially regulates their growth. Understanding the dynamical interplay between all these processes requires supercomputer simulations, through which we hope to elucidate the physics that shapes the objects that we observe through our telescopes across all wavebands from gamma rays to radio. Such simulations produce enormous volumes of data that must be stored, analysed, and disseminated in order to maximize their scientific value to the community. By combining simulations with advancing observations from MeerKAT and other telescopes, we hope to eventually to produce a true-to-life movie of the evolution of the observable Universe from the Big Bang until today.

Dr. Chamandy is a postdoctoral fellow at the University of Rochester. His research: Magnetic fields exist almost everywhere in the universe, and play a crucial role in many astrophysical processes. The evolution of magnetic fields within galaxies over cosmic time is governed by magnetohydrodynamics. Dr. Chamandy and his fellow researchers are in the process of developing a hybrid scheme, wherein output from a semi-analytic galaxy evolution model (GALFORM), which in turn uses output from a cosmological dark matter simulation (MILLENIUM), is used as input for galactic dynamo mean-field simulations. These simulations solve a suitably simplified set of MHD equations to compute the magnetic field for each galaxy. Thus we hope to simulate the temporal and spatial evolution of the magnetic fields of >10^7 galaxies over cosmological timescales and volumes. The goal is to produce mock MeerKAT/SKA radio polarization data sets and images, which can then be compared with observations.

Lauren uses simulations of the universe to trace light rays from far away objects to us in order to see how the magnetic fields along the way will change the polarisation of the light.
These simulations are massive and since she wants to look far back in space (and time), a large amount of computational resources are necessary for the project.
Sam is a PhD student at UCT, funded by the SKA SA project and under the supervision of Prof. Russ Taylor. His research seeks to explore large-scale magnetic fields in disk galaxies.
To this end he probes the properties of magnetic fields through wide-field radio polarimetry. This relies heavily on large data products of SKA precursors (early MeerKAT and KAT7) and complementary data from the Indian Giant Metrewave Radio Telescope.
He requires this type of datasets so to provide the coverage required to probe the polarization behavior across a wide frequency range. Similar studies in the past have had a narrow frequency coverage that limited application of the Fourier space transform (rotation measure synthesis) nature of the main tools used.
