Beam Perturbation impact on Calibration and the 21cm Power Spectrum

We study the impact of broken dipoles in the Murchison Widefield Array (MWA) on the detectibility of a signal from the Epoch of Reionisation.

The results are published in: Ronniy C Joseph, C M Trott, R B Wayth, A Nasirudin, Calibration and 21-cm power spectrum estimation in the presence of antenna beam variations, Monthly Notices of the Royal Astronomical Society, Volume 492, Issue 2, February 2020, Pages 2017–2028, https://doi.org/10.1093/mnras/stz3375
