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 ...
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 ...
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 ...
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 ...
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 ...
