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…
Square Kilometre Array Science Data Challenge 3a: foreground removal for an EoR experiment
A. Bonaldi, P. Hartley, R. Braun +179
We present and analyse the results of the Science data challenge 3a (SDC3a, https://sdc3.skao.int/challenges/foregrounds), an EoR foreground-removal community-wide exercise organis…
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…
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…
Verifying the Australian MWA EoR pipeline II: fundamental limits of the AusEoRPipe and the impact of instrumental effects
J. L. B. Line, C. M. Trott, N. Barry +2
Detection of the weak cosmological signal from high-redshift hydrogen demands careful data analysis and an understanding of the full instrument signal chain. Here we use the WODEN…
