Advances on the classification of radio image cubes
Steven Ndung'u, Trienko Grobler, Stefan J. Wijnholds +2
Modern radio telescopes will daily generate data sets on the scale of exabytes for systems like the Square Kilometre Array (SKA). Massive data sets are a source of unknown and rare…
Feature Guided Training and Rotational Standardisation for the Morphological Classification of Radio Galaxies
Kevin Brand, Trienko L. Grobler, Waldo Kleynhans +3
State-of-the-art radio observatories produce large amounts of data which can be used to study the properties of radio galaxies. However, with this rapid increase in data volume, it…
CNN Architecture Comparison for Radio Galaxy Classification
Burger Becker, Mattia Vaccari, Matthew Prescott +1
The morphological classification of radio sources is important to gain a full understanding of galaxy evolution processes and their relation with local environmental properties. Fu…
Foreground modelling via Gaussian process regression: an application to HERA data
Abhik Ghosh, Florent Mertens, Gianni Bernardi +70
The key challenge in the observation of the redshifted 21-cm signal from cosmic reionization is its separation from the much brighter foreground emission. Such separation relies on…
Radio Interferometric Calibration Using a Complex Student's t-distribution and Wirtinger Derivatives
Ulrich Armel Mbou Sob, Hertzog Landman Bester, Oleg Smirnov +2
Radio interferometric gain calibration can be biased by incomplete sky models and radio frequency interference, resulting in calibration artefacts that can restrict the dynamic ran…
Visualization of Fractional Integrals
Trienko Lups Grobler
We presented a novel geometric interpretation of the Riemann-Liouville fractional integral. We found that a Riemann-Liouville integral can be thought of as the area obtained by sum…
