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…

The REACH radiometer for detecting the 21-cm hydrogen signal from redshift 7.5 to 28

E. de Lera Acedo, D. I. L. de Villiers, N. Razavi-Ghods +31

Observations of the 21-cm line from primordial hydrogen promise to be one of the best tools to study the early epochs of the Universe: the Dark Ages, the Cosmic Dawn, and the subse…

Radio antenna design for sky-averaged 21 cm cosmology experiments: the REACH case

J. Cumner, E. De Lera Acedo, D. I. L. de Villiers +35

Following the reported detection of an absorption profile associated with the 21~cm sky-averaged signal from the Cosmic Dawn by the EDGES experiment in 2018, a number of experiment…
