Disentangling star formation and AGN activity in the GAMA (G23) region
(University of the Western Cape, 2021)
Observations of galaxies at di↵erent wavelengths have shaped our understanding of their
formation and evolution through time. The commonly derived parameters, such as stellar
mass and star formation rate (SFR), rely on ...
Radiometric study of soil: the systematic effects
(University of the Western Cape, 2007)
The natural 238U, 232Th and 40K radioactive content of vineyard soil was measured with an in-situ gamma-ray detector. The activity concentrations measured with the in-situ detector are normalized using the laboratory-determined ...
Computational modelling of a hot-wire chemical vapour deposition reactor chamber
(University of Western Cape, 2020)
In this thesis, I explore the subjects of fluid dynamics and the Hot-Wire Chemical Vapour
Deposition (HWCVD) process. HWCVD, in its simplicity, is one of the more powerful and
elegant deposition techniques available in ...
Radon in the Cango Caves
(University of the Western Cape, 2005)
Radon is a naturally occurring radioactive element in the 238U decay series that is found in high concentrations in certain geological formations such as Caves. Exposure to high concentrations of radon has been positively ...
Determination of natural radioactivity concentrations in soil: a comparative study of Windows and Full Spectrum Analysis
(University of the Western Cape, 2004)
In this study, two methods of analysing activity concentrations of natural radionuclides (U, Th and K) in soil are critically compared. These are the Window Analysis (WA) and Full Spectrum Analysis (FSA). In the usual WA ...
Probing large-scale structure with the SKAO and other cosmological surveys
(University of the Western Cape, 2022)
In recent history there have been several advances in cosmology, which has significantly
shaped our understanding of the Universe. The current leading theory is called ΛCDM,
which can successfully model the expansion of ...
Radon exhalation studies for applications in low background environments.
(University of the Western Cape, 2022)
Neutrinoless double beta decay (0 ) 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 ...
