We also found that the foreground leakage is worse when edge antennas are included, as they have a more different primary beam compared to antennas at the centre of the array. The leakage magnitude is worse when bright foregrounds appear in the antenna sidelobes, as expected. Our simulations provide a useful framework to interpret observations and assess which power spectrum region is expected to be most contaminated by foreground power leakage.]]> Wed 12 May 2021 14:24:29 SAST ]]> TiRiFiG, a graphical 3D kinematic modelling tool https://commons.ru.ac.za/vital/access/manager/Repository/vital:30558 Thu 13 May 2021 06:10:31 SAST ]]> Observations of diffuse radio emission in the Abell 773 galaxy cluster https://commons.ru.ac.za/vital/access/manager/Repository/vital:38394 Thu 13 May 2021 05:41:52 SAST ]]> A 150 MHz all sky survey with the Precision Array to Probe the Epoch of Reionization https://commons.ru.ac.za/vital/access/manager/Repository/vital:34556 Thu 13 May 2021 04:40:36 SAST ]]> Foreground simulations for observations of the global 21-cm signal https://commons.ru.ac.za/vital/access/manager/Repository/vital:30557 Thu 13 May 2021 01:46:55 SAST ]]>
