Functional Analysis of Widefield Radio Interferometry
Nichole Barry, Jaiden Cook, Cathryn Trott +2
Radio interferometry relies on reconstruction techniques to form images from discrete visibility measurements. As instruments encompass wider fields of view, the nuance of that rec…
GLEAM-300: The GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey at 300 MHz
S. W. Duchesne, J. H. Cook, N. Hurley-Walker +11
In this paper we present a wide-field radio survey at 300 MHz covering the sky from using the Murchison Widefield Array (MWA). Th…
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…
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…
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…
Verifying the Australian MWA EoR pipeline I: 21-cm sky model and correlated measurement density
J. L. B. Line, C. M. Trott, J. H. Cook +3
We present the first of two papers dedicated to verifying the Australian Epoch of Reionisation pipeline (AusEoRPipe) through simulation. The AusEoRPipe aims to disentangle 21-cm ra…
The Impact of ionization Morphology and X-ray Heating on the Cosmological 21cm Skew Spectrum
J. H. Cook, S. Balu, B. Greig +4
The cosmological 21cm signal offers a potential probe of the early Universe and the first ionizing sources. Current experiments probe the spatially-dependent variance (Gaussianity)…
Aliasing from Galactic Plane Setting in Widefield Radio Interferometry
N. Barry, J. L. B. Line, C. R. Lynch +2
Measurements with widefield radio interferometers often include the near-infinite gradient between the sky and the horizon. This causes aliasing inherent to the measurement itself,…
Imaging at 300 MHz With the MWA
J. H. Cook, N. Seymour, M. Sokolowski
At relatively high frequencies, highly sensitive grating sidelobes occur in the primary beam patterns of low frequency aperture arrays (LFAA) such as the Murchison Widefield Array…
