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…

The Murchison Widefield Array Phase III upgrade: Sensitivity Doubled, Number of Baselines Quadrupled, Flexibility Enhanced, and EoR Observations Optimised

S. J. Tingay, M. Johnston-Hollitt, R. B. Wayth +32

We describe the latest iteration of upgrades (designated Phase III) to the Murchison Widefield Array (MWA), in the fourth paper in a series that covers the evolution of the telesco…

Determining Ideal Fields for Epoch of Reionisation Science Using the 21 cm Line

E. Jong, C. Trott, C. D. Nunhokee +1

The upcoming Square Kilometre Array Low Frequency (SKA-Low) interferometer will have the required sensitivity to detect the 21 cm line from neutral hydrogen during the Epoch of Rei…

Improved limits on the 21cm signal at z=6.5-7.0 with the MWA using Gaussian information

Cathryn M. Trott, C. D. Nunhokee, D. Null +29

We explore the properties of interferometric data from high-redshift 21~cm measurements using the Murchison Widefield Array. These data contain redshifted 21~cm signal, contaminati…

A demonstration of the effect of fringe-rate filtering in the Hydrogen Epoch of Reionization Array delay power spectrum pipeline

Hugh Garsden, Philip Bull, Mike Wilensky +94

Radio interferometers targeting the 21cm brightness temperature fluctuations at high redshift are subject to systematic effects that operate over a range of different timescales. T…

Limits on the 21 cm power spectrum at z=6.5-7.0 from MWA observations

C. D. Nunhokee, D. Null, C. M Trott +29

This paper presents the spherically-averaged 21 cm power spectrum derived from Epoch of Reionization (EoR) observations conducted with the Murchison Widefield Array (MWA). The anal…
