We generated an all-sky catalogue of 88 sources down to a flux density of 5 Jy. Moreover, we measured both polarized point source and the Galactic diffuse emission, and used these measurements to constrain our model of polarization leakage. We find the leakage due to a population of point sources to be 12% lower than the prediction from our polarized model.]]> Thu 13 May 2021 05:43:39 SAST ]]> Observations of diffuse radio emission in the Abell 773 galaxy cluster https://commons.ru.ac.za/vital/access/manager/Repository/vital:38394 Thu 13 May 2021 05:41:52 SAST ]]> A pilot wide-field VLBI survey of the GOODS-North field https://commons.ru.ac.za/vital/access/manager/Repository/vital:30027 5x105 K and >6x1021 W Hz-1 respectively. This work demonstrates that automated post-processing pipelines for wide-field, uniform sensitivity VLBI surveys are feasible and indeed made more efficient with new software, wide-field imaging algorithms and more purpose-built source- finders. This broadens the discovery space for future wide-field surveys with upcoming arrays such as the African VLBI Network (AVN), MeerKAT and the Square Kilometre Array (SKA).]]> Thu 13 May 2021 05:08:27 SAST ]]> A 150 MHz all sky survey with the Precision Array to Probe the Epoch of Reionization https://commons.ru.ac.za/vital/access/manager/Repository/vital:34556 Thu 13 May 2021 04:40:36 SAST ]]> Foreground simulations for observations of the global 21-cm signal https://commons.ru.ac.za/vital/access/manager/Repository/vital:30557 Thu 13 May 2021 01:46:55 SAST ]]> Advanced radio interferometric simulation and data reduction techniques https://commons.ru.ac.za/vital/access/manager/Repository/vital:26875 Thu 13 May 2021 01:03:59 SAST ]]> Accelerated implementations of the RIME for DDE calibration and source modelling https://commons.ru.ac.za/vital/access/manager/Repository/vital:42199 Thu 13 Jul 2023 12:40:08 SAST ]]>
