New collective structures in the Z=76 stable odd neutron nucleus, 187Os
(University of Western Cape, 2021)
Low- and medium-spin bands of 187Os have been studied using the AFRODITE array,
following the 186W(4He,3n)187Os reaction at a beam energy of 37 MeV. The measurements
of
coincidences, angular distribution ratios ...
Probing galaxy evolution below the noise threshold with radio observations
(University of the Western Cape, 2020)
The faint radio population consisting of star forming galaxies (SFG) and radio-quiet
active galactic nuclei (AGN) is important in the study of galaxy evolution. However,
the bulk of the faint population is below the ...
Application of anomaly detection techniques to astrophysical transients
(University of Western Cape, 2021)
We are fast moving into an era where data will be the primary driving factor for discovering new
unknown astronomical objects and also improving our understanding of the current rare astronomical
objects. Wide field ...
Structural properties and optical modelling of SiC thin films
(University of the Western Cape, 2020)
Amorphous silicon carbide (a-SiC) is a versatile material due to its interesting mechanical, chemical and optical properties that make it a candidate for application in solar cell technology. As a-SiC stoichiometry can be ...
The effects on student knowledge and engagement when using a culturally responsive framework to teach ASTR 101
(University of the Western Cape, 2020)
The U.S. has a problem: it is not effectively utilizing all the bright young minds available to its science & engineering workforce. In 2012 the President’s Council of Advisors on Science and Technology (PCAST) reported ...
Radiometric investigation of soil and beach sand in Zanzibar
(University of the Western Cape, 2020)
This study presents the results of radiometric investigation of soil and beach sand in Zanzibar. The activity concentration of natural radionuclides (40K, and 232Th and 238U decay products) in beach sand and soil samples ...
Cosmology with HI intensity mapping: effect of higher order corrections
(University of the Western Cape, 2020)
One of the main challenges of cosmology is to unveil the nature of dark energy
and dark matter. They can be constrained with baryonic acoustic oscillations
(BAO) and redshift space distortions, amongst others. Both have ...
Reconstruction of the ionization history from 21cm maps with deep learning
(University of the Western Cape, 2020)
Upcoming and ongoing 21cm surveys, such as the Square Kilometre Array (SKA), Hydrogen
Epoch of Reionization Array (HERA) and Low Frequency Array (LOFAR), will enable imaging
of the neutral hydrogen distribution on ...
An investigation into the morphology of radio sources
(University of Western Cape, 2021)
Radio galaxies are some of the most unusual and powerful objects in the Universe
and are therefore vital for so many reasons. Studies of Radio-Loud Active
Galactic Nuclei (AGN) gives us the potential to enhance our ...
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 ...
