The Impact of GSM towers in Radio Astronomy
Isaac Sihlangu, Nadeem Oozeer
Radio astronomy is a specialised area of astronomy that examines the radio emissions from astronomical bodies within the electromagnetic spectrum's radio range. As radio telescopes…
Mining Mini-Halos with MeerKAT I. Calibration and Imaging
K. S. Trehaeven, V. Parekh, N. Oozeer +7
Radio mini-halos are clouds of diffuse, low surface brightness synchrotron emission that surround the Brightest Cluster Galaxy (BCG) in massive cool-core galaxy clusters. In this p…
SKA Science Data Challenge 2: analysis and results
P. Hartley, A. Bonaldi, R. Braun +105
The Square Kilometre Array Observatory (SKAO) will explore the radio sky to new depths in order to conduct transformational science. SKAO data products made available to astronomer…
Trajectory Based RFI Subtraction and Calibration for Radio Interferometry
Chris Finlay, Bruce A. Bassett, Martin Kunz +1
Radio interferometry calibration and Radio Frequency Interference (RFI) removal are usually done separately. Here we show that jointly modelling the antenna gains and RFI has signi…
Nature and Evolution of UHF and L-band Radio Frequency Interference at the MeerKAT Radio Telescope
Isaac Sihlangu, Nadeem Oozeer, Bruce Bassett
Radio Frequency Interference (RFI) is unwanted noise that swamps the desired astronomical signal. Radio astronomers have always had to deal with RFI detection and excision around t…
