Measuring the quasar luminosity function below the detection threshold
(University of the Western Cape, 2016)The radio emission of radio-quiet active galactic nuclei (AGN) is thought to be from star formation and AGN related emission. I investigate these sources using 1.4 GHz radio data from FIRST and three optical quasars samples ... -
Measuring transitional matrix elements using first-order perturbation theory in Coulomb excitation
(University of the Western Cape, 2019)The aim of nuclear structure physics is to study the interplay between singleparticle and collective degrees of freedom in nuclei and to explain how nuclei get excited and decay under di erent external conditions, such ... -
Metal assisted chemically etched silicon nanowires for application in a hybrid solar cell
(University of the Western Cape, 2018)Photovoltaic (PV) devices based on inorganic-organic hybrid active layers have been extensively studied for over a decade now. However, photoactive hybrid layers of material combinations such as rr-P3HT and SiNWs still ... -
Metal oxide nanocrystalline thin films as buffer layers in organic/ hybrid solar cells
(University of Western Cape, 2019)Without reverting to encapsulation, organic bulk - heterojunction solar cells can be protected from the oxidation of the highly reactive low work function cathode metal electrode, by the deposition of metal oxide buffer ... -
Mock HI spectral line stacking experiments for large galaxy surveys
(University of Western Cape, 2019)The study of neutral atomic hydrogen (HI) plays a vital role in improving the knowledge about galaxy evolution since HI serves as the raw fuel for star formation. However, the current knowledge about it is limited to the ... -
Modeling of the dispersion of radionuclides around a nuclear power station
(University of the Western Cape, 2009)Nuclear reactors release small amounts of radioactivity during their normal operations. The most common method of calculating the dose to the public that results from such releases uses Gaussian Plume models. We are ... -
Modelling and measurement of radon diffusion through soil application on mine tailings dams.
(University of Western Cape, 2004)Radon (222Rn) has been identified as an important factor that could result in a health hazard by studies all around the world. The health risks can be minimised by preventive measures where radon is highly concentrated as ... -

Modelling radio galaxies in the Millennium simulation: SKA/MeerKAT sources and CMB contaminants
(University of the Western Cape, 2010)We investigate the modelling of radio galaxies within a semi-analytic framework in the Millennium Simulation of the Virgo Consortium. The aim is to assess the radio sources contamination of Sunyaev-Zeldovich (SZ) signatures ... -
Monte carlo simulations of complex germanium escape suppression spectrometers with MCNPX a case study
(University of the Western Cape, 2009)Gamma ray spectroscopy has provided enormous amounts of information on the behaviour and structure of atomic nuclei [SHA88, BEA92, EBE08]. Most of the major discoveries in experimental nuclear physics over the last five ... -
A multi-scale study of the star formation law in nearby galaxies
(University of the Western Cape, 2020)This research aimed to evaluate the effects of changing length-scales on the star formation laws and star formation efficiencies for our selected sample of galaxies. We have combined high-resolution Hi data from The Hi ... -
Nano-rods WO3-δ for electrochromic smart windows applications
(University of the Western Cape, 2006)Tungsten oxide is a good electrochromic material which has been used in the construction of smart windows through visible modulation. These smart materials can reversibly change their optical properties with the application ... -
The nature of the microjy source population
(University of the Western Cape, 2015)The study of the faint radio universe and of its properties has recently become a very active field of research not only because of the much improved capabilities of the SKA pathfinders but also because of the need to ... -
Neutral hydrogen intensity mapping on small scales using MeerKAT
(University of the Western Cape, 2021)In the post-reionisation universe, intensity mapping (IM) with the 21 cm line of neutral hydrogen (HI) provides a potential means of probing the large-scale structure of the universe. With such a probe, a wide variety of ... -

New bands in ¹⁹²Tl using gamma spectroscopy techniques
(University of the Western Cape, 2011)High spin excited stats in¹⁹²Tl were studied using gamma-ray spectroscopy. The study included taking an active part in performing the experiment, understanding the experimental procedure, electronics and data acquisition ... -
Nitrogen and argon treatment of titanium dioxide nanowire arrays
(University of the Western Cape, 2021)TiO2 nanoparticle films are important electron transport layers (ETLs) in photovoltaics such as dye-sensitised, perovskite and polymer hetero-junction solar cells. These films, however, have significant electron trap-sites ... -
