Probabilistic methods for radio interferometry data analysis by Natarajan, Iniyan

“…We first develop the theory for employing the RIME in performing Bayesian analysis of interferometric data. We then apply this to the problem of super-resolution with radio interferometers by performing model selection successfully between different source structures, all smaller in scale than the size of the point spread function (PSF) of the interferometer, on Westerbork Synthesis Radio Telescope (WSRT) simulations at a frequency of 1.4 GHz. …”

Exploring the evolution and hidden large-scale structures of galaxies with MeerKAT HI surveys by Rajohnson, Sambatriniaina Hagiriche Aycha

“…To independently verify the derived H I properties, I cross-referenced fluxes from COSMOS detections with ALFALFA galaxies, revealing agreement for high-signal-to-noise ratio sources. As an application of the data verification process, I constructed the H I size-mass relation, investigating potential systematic eects present in the early data. …”

InSAR time series analysis and machine learning for ground subsidence monitoring and susceptibility mapping in Midvaal, South Africa by Maluleka, Thobani

“…Despite the severity of this issue, existing methodologies for monitoring and mapping ground subsidence susceptibility are limited by inefficiencies, labour-intensive processes, and reliance on sparse data sources, leading to delayed and inaccurate risk assessments. …”

HI survey of local group dwarf galaxies by Namumba, Brenda

“…This thesis investigates the HI properties of 3 dwarf irregular galaxies and one blue compact dwarf galaxy of the Local Group. The data set of each dwarf irregular galaxy was obtained with the Karoo Array Telescope (KAT-7) while the blue compact dwarf was observed with the Dominion Radio Astrophysical Observatory (DRAO) synthesis telescope. …”
