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…
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…
The Necessity of Individually Validated Beam Models for an Interferometric Epoch of Reionization Detection
A. Chokshi, N. Barry, J. L. B. Line +3
A first statistical detection of the 21-cm Epoch of Reionization (EoR) is on the horizon, as cosmological volumes of the Universe become accessible via the adoption of low-frequenc…
Strategy for mitigation of systematics for EoR experiments with the Murchison Widefield Array
Chuneeta D. Nunhokee, Dev Null, Cathryn M. Trott +4
Observations of the 21 cm signal face significant challenges due to bright astrophysical foregrounds that are several orders of magnitude higher than the brightness of the hydrogen…
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…
