Direct Primary Beam Correction: Untangling Mutual Coupling in 21-cm Cosmological Experiments with the SKA-Low Radio Telescope
Oscar S. D. O'Hara, Quentin Gueuning, Eloy de Lera Acedo +7
The paper presents Direct Primary Beam Correction, a method that uses regularized inversion of stacked Jones matrices to reconstruct and correct the far‑field beam pattern of SKA‑L…
Observations of the Cosmic Dawn and Epoch of Reionization with the SKAO: Observational Lessons Learned from Precursors and Pathfinder Instruments
Eloy de Lera Acedo, James Aguirre, Dominic Anstey +34
This chapter summarizes the observational lessons learned after two decades of observations of the Cosmic Dawn (CD) and Epoch of Reionization (EoR) with SKAO pathfinders and precur…
A Fast Direct Solver for Mutual Coupling Analysis of Large Arrays of Reflector Antennas
Quentin Gueuning, Eloy de Lera Acedo, Anthony Keith Brown +1
Mutual coupling is a dominant systematic effect in dense reflector arrays, imprinting direction-dependent and frequency-dependent structure on embedded element patterns (EEPs) and…
Uncovering the Effects of Array Mutual Coupling in 21-cm Experiments with the SKA-Low Radio Telescope
Oscar S. D. O'Hara, Quentin Gueuning, Eloy de Lera Acedo +8
We investigate the impact of Mutual Coupling (MC) between antennas on the time-delay power spectrum response of the core of the SKA-Low radio telescope. Using two in-house tools -…
