Detecting Galaxies in the Epoch of Reionization
(University of the Western Cape, 2017)
The aim of this project was to develop a technique that allows us to measure the redshift
of radio galaxies in the Epoch of Reionization. We achieved this by constructing
a parameterization of the 21-cm absorption feature ...
Coupling of single neutron configurations to collective core excitations in 162Yb using 163Yb
(University of the Western Cape, 2017)
In odd-nuclei the single nucleon can couple to collective excitations of its even-even core
nucleus . These collective excitations lie within the pairing gap and are therefore the
lowest energy excitations of the core. Our ...
Point source simulations and Foreground cleaning techniques for HI intensity mapping
(University of the Western Cape, 2018)
We created a full sky point source catalogue at frequencies around 1 GHz, including
the intensity, polarisation, rotation measure and spectral index of the point source.
These values were matched to data where available ...
Galaxy Clustering as a Probe for Galaxy Evolution in Simulations
(University of the Western Cape, 2017)
Studying clustering on small scales (<10Mpc) over a large span of red-
shifts allows us to connect galaxies to underlying cosmic large-scale
structure, and thereby provide constraints on the physical processes
that drive ...
Validation of Gamma Ray spectrometry process used to determine the radionuclides and radioactivity levels in decorative Granite countertops.
(University of the Western Cape, 2016)
Humans are continuously exposed to low level of ionizing radiation, sources include
soil, medical treatment and as well as radiation emissions from natural materials like
granite rocks. The radiation levels present in these ...
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 ...
Isothermal and non-isothermal comparative study of zn-sn system using real-time rbs
(University of the Western Cape, 2021)
Insight into the effects of isothermal and non-isothermal annealing on bi-metallic thin film is
important for material synthesis and application in everyday use. The effects of isothermal
annealing on bi-metallic thin ...
Anomaly Detection With Machine Learning In Astronomical Images
(University of the Western Cape, 2020)
Observations that push the boundaries have historically fuelled scientific breakthroughs, and these observations frequently involve phenomena that were previously unseen and unidentified. Data sets have increased in size ...
Study of low-lying proton unbound states in 24Al using the 24Mg(3He; t)24Al reaction.
(University of the Western Cape, 2022)
This MSc project entails a study of astrophysically relevant states in 24Al,
that are important for a better understanding of the 23Mg(p,
)24Al nuclear
reaction rate in classical novae. This is a crucial breakout reaction ...
Synthesis and characterization of ion implanted Pd/Ti/V/Pd/Ti based multilayer thin films using rutherford backscattering spectrometry (rbs) and elastic recoil detection analysis (erda) for hydrogen storage application
(University of the Western Cape, 2022)
Hydrogen is regarded as an attractive, pollution-free energy carrier for future energy systems,
supported by its efficient energy conversion. Still, the challenge is its storage and transportation.
Hydrogen can either ...
