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.
