Sarah Blyth is a senior lecturer at the UCT Department of Astronomy. She is one of the Principal Investigators of the upcoming LADUMA survey which will use the MeerKAT radio telescope to study the gas in galaxies back to when the universe was one third of its current age. This project will involve the deepest observations of neutral hydrogen in galaxies to date combined with cross-matching to other large datasets across the electromagnetic spectrum. Sarah plans to use IDIA to process and analyse this upcoming very large dataset to investigate the evolution of galaxies over cosmic time.

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.

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.

Prof.  Kraan-Korteweg's research is focused on mapping the large-scale structures in the nearby Universe with special emphasis on unveiling the Zone of Avoidance through various multi-wavelengths approaches (optical, NIR, MIR, radio, X-ray) - including systematic whole-sky HI-surveys and peculiar velocity studies.

She is an active participant in various MeerKAT HI Large Survey Projects. In preparation for this, she is pursuing precursor projects, which involve testing galaxy extraction pipelines based on a large ZOA WSRT mosaic, and a to-be proposed MeerKAT early science project.

The latter has the goal to map the core of a optically hidden massive supercluster as science objective, and will function as a pilot project for assessing the reliability of galaxy extraction and parameterisation tool that the MeerKAT Laduma and Fornax HI Large Survey Projects will apply.

Prof. Santos is an associate professor at the University of Western Cape. His main focus is "radio-cosmology" - studying how the next generation of large radio telescopes, such as MeerKAT in South Africa and the future SKA will be able to answer fundamental questions in Cosmology.

This involves large simulations where we need to take into account the signal, contaminants and the effects of the telescope itself. Moreover, it will require the application of demanding cleaning algorithms and calibration methods to huge data sets, something that is the realm of Big Data.

Prof. Woudt is the Head of the Astronomy Department at the University of Cape Town.

His research specialisation is the physics of accretion onto white dwarfs in mass-transferring close binaries. He pursues this research topic through (1) the study of rapid oscillations in cataclysmic variables, (2) the study of ultracompact helium-transferring binaries, and (3) optical and radio transient surveys.

He is an expert in high time-domain astrophysics of cataclysmic variables. He co-leads the MeerKAT large survey project ThunderKAT (radio transients) and the associated MeerLICHT project.

At IDIA, Prof. Woudt and fellow researchers will process the data stream from the MeerKAT Large Survey Project, ThunderKAT, over a range of time-scales (hours, days, weeks, months), as well as process data from the MeerLICHT telescope in real-time.

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.

Jon holds a SKA research fellowship jointly at UWC and UCT. He completed his PhD in observational cosmology through radio astronomy in 2007, in particular using radio-continuum studies of the Cosmic Microwave Background to search for clusters of galaxies using the so-called Sunyaev-Zel'dovich effect.

He specializes in statistical (especially Bayesian) analyses of interferometric data, whether in radio maps or directly in the 'visibility' domain in which they are taken. He models the noise properties of the data, in order to extract the maximum amount of information possible.

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.
