The Design of an Anti-Aliasing Filter for the Next Generation Digitiser
MeerKAT, is a 64-element radio astronomy antenna array which has been recently constructed in the Northern Cape Province of South Africa. It serves as South Africa's contribution towards the international Square Kilometre Array (SKA) project. The MeerKAT array has been designed to observe radio …

Radio Frequency Interference: Simulations for Radio Interferometry Arrays
… for astronomy in the era of the Square Kilometre Array (SKA). Traditionally RFI is dealt with through simple algorithms that remove unexpected rapid changes but the recent explosion of machine learning and artificial intelligence (AI) provides an exciting opportunity for pushing the …

A scalable packetised radio astronomy imager
… popularity for ever larger interferometric arrays, the processing requirements for these back-ends have increased significantly. While the techniques for building these back-ends are well understood, every installation typically still takes many years to develop as the instruments use highly …

The automated detection and multiwavelength properties of LADUMA HI galaxies
… the Looking At the Distant Universe with the MeerKAT Array (LADUMA) survey. LADUMA is a deep and narrow HI emission survey underway with the MeerKAT telescope. We perform automated source finding over the low redshift Early Science LADUMA data cube using the SoFiA-2 algorithm. The source …

The cosmic web in the Laduma field
… by the Looking at the Distant Universe with the MeerKAT Array (LADUMA) survey at higher redshifts. LADUMA's ancillary data catalogue provides a limited sample of spectroscopic redshift measurements across LADUMA's target volume. I use the DisPerSE software package to identify large-scale …

Searching for an optical counterpart to Fast Radio Bursts
… specifically to observe simultaneously with the MeerKAT array near Carnarvon. This means that we have a unique opportunity to search for new FRBs using MeerKAT, and to see any associated optical emission with MeerLICHT, regardless of whether the FRBs found by MeerKAT are rare repeaters, or the …

The MeerKAT Radio Frequency Interference Environment
… are few dedicated RFI monitoring systems on the MeerKAT site, the most sensitive RFI detector is the MeerKAT array itself. In this thesis we use approximately 1500 hours of MeerKAT observations to create a multi-dimensional view of the RFI at the MeerKAT site. Here we investigate a probabilistic …
