Radon exhalation studies for applications in low background environments.
(University of the Western Cape, 2023)
Neutrinoless double beta decay (0νββ) is a rare process that is yet to be observed. Observation of neutrinoless double beta decays would imply lepton number violation, and that the neutrino is its own antiparticle (a
Majorana ...
Supervised machine learning techniques for radio source classification
(University of the Western Cape, 2023)
Classification is one of the most fundamental aspects of scientific investigation. Astronomers have thus developed several classification schemes to try and make sense of the evolving properties of planets, stars and ...
HI intensity mapping: Impact of primary beam effects
(University of the Western Cape, 2023)
Neutral hydrogen (HI) intensity mapping surveys with upcoming and future radio telescopes
such as the MeerKAT, a precursor to the Square Kilometre Array Observatory
(SKAO) MID telescope, have great potential for constraining ...
Machine learning approaches to study star formation and black hole accretion in the Meerkat/MIGHTEE survey
(University of the Western Cape, 2023)
Galaxy formation and evolution are driven by two main physical processes: star formation and black hole accretion. Both processes can be traced via the synchrotron emission at radio wavelengths. However, a reliable ...
Physics graduate preparedness for work and society
(University of the Western Cape, 2023)
Both internationally and in South Africa, there have been renewed debates about the purposes of higher education and the attributes that should be developed in graduates. In the field of physics, many studies have reported ...
Accelerating reionization simulations using machine learning
(University of the Western Cape, 2023)
Epoch of Reionization (EoR) refers to the time in the history of the universe when the appearance of the first luminous sources reionized the intergalactic medium (IGM). The EoR carries a wealth of information regarding ...
Chemical pressure-induced transition of the magnetic ground state from ferromagnetic to antiferromagnetic order in CeCuGe and DyCuIn alloys
(University of the Western Cape, 2023)
Rare-earth intermetallic compounds continue to attract considerable attention, due to their fundamental importance in understanding physical properties and potential applications based on a variety of phenomena. The ternary ...
Structural features of air-processible methyl ammonium lead triiodide (MAPbI3) perovskite thin films grown on Al-doped ZnO Nanowire Arrays
(University of the Western Cape, 2023)
The performance of air stable, mixed halide (MAPbI3-xClx) perovskite based solar cells is highly dependent on the quality and stability of the perovskite thin film, which in turn, is dependent on the substrate on which it ...
Exploring poly (2, 5) benzimidazole enhanced with carbon nanotubes for space applications
(University of the Western Cape, 2023)
This work explores using polymeric materials for space radiation shielding in low-earth orbit. Shielding against radiation is essential on any space mission. Low atomic number materials, such as hydrogen, have shown to be ...
Sample selection effects in laduma stacking experiments
(University of the Western Cape, 2023)
This study explores the impact of selection effects introduced by input optical cata-logues on high-redshift stacking experiments. Using the Hi stacking technique, the Hi content of LADUMA synthetic data cubes is analyzed ...
