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 ...
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 ...
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 ...
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 ...
The interstellar medium scaling relations in cosmological simulations
(University of the Western Cape, 2022)
This work presents the scaling relations for the redshift zero galaxies in the SIMBA1
cosmological hydrodynamic simulations. The aim is to test the degree to which the
SIMBA simulations reproduce the physical properties ...
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 ...
HI intensity mapping: Impact of primary beam effects
(University of the Western Cape, 2023)
Neutral hydrogen (HI) intensity mapping surveys with upcoming and future radio telescopes
such as the MeerKAT, a precursor to the Square Kilometre Array Observatory
(SKAO) MID telescope, have great potential for constraining ...
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 ...
