Optimising MWA EoR data processing for improved 21 cm power spectrum measurements -- fine-tuning ionospheric corrections
J. Kariuki Chege, C. H. Jordan, C. Lynch +4
The redshifted cosmological 21 cm signal emitted by neutral hydrogen during the first billion years of the universe is much fainter relative to other galactic and extragalactic rad…
The MWA Long Baseline Epoch of Reionisation Survey: I. Improved Source Catalogue for the EoR 0 field
C. R. Lynch, T. J. Galvin, J. L. B. Line +6
One of the principal systematic constraints on the Epoch of Reionisation (EoR) experiment is the accuracy of the foreground calibration model. Recent results have shown that highly…
Epoch of Reionization Power Spectrum Limits from Murchison Widefield Array Data Targeted at EoR1 Field
M. Rahimi, B. Pindor, J. L. B. Line +28
Current attempts to measure the 21cm Power Spectrum of neutral hydrogen during the Epoch of Reionization are limited by systematics which produce measured upper limits above both t…
Constraining the 21cm brightness temperature of the IGM at =6.6 around LAEs with the Murchison Widefield Array
Cathryn M. Trott, C. H. Jordan, J. L. B. Line +29
The locations of Ly- emitting galaxies (LAEs) at the end of the Epoch of Reionisation (EoR) are expected to correlate with regions of ionised hydrogen, traced by the redshifted…
A new MWA limit on the 21 cm Power Spectrum at Redshifts 13 17
S. Yoshiura, B. Pindor, J. L. B. Line +29
Observations in the lowest MWA band between MHz have the potential to constrain the distribution of neutral hydrogen in the intergalactic medium at redshift .…
Deep multi-redshift limits on Epoch of Reionisation 21cm Power Spectra from Four Seasons of Murchison Widefield Array Observations
Cathryn M. Trott, C. H. Jordan, S. Midgley +33
We compute the spherically-averaged power spectrum from four seasons of data obtained for the Epoch of Reionisation (EoR) project observed with the Murchison Widefield Array (MWA).…
Gridded and direct Epoch of Reionisation bispectrum estimates using the Murchison Widefield Array
Cathryn M. Trott, Catherine A. Watkinson, Christopher H. Jordan +42
We apply two methods to estimate the 21~cm bispectrum from data taken within the Epoch of Reionisation (EoR) project of the Murchison Widefield Array (MWA). Using data acquired wit…
Robust statistics toward detection of the 21 cm signal from the Epoch of Reionisation
Cathryn M. Trott, Shih Ching Fu, Steven Murray +26
We explore methods for robust estimation of the 21 cm signal from the Epoch of Reionisation (EoR). A Kernel Density Estimator (KDE) is introduced for measuring the spatial temperat…
A Clustered Extragalactic Foreground Model for the EoR
Steven Murray, Cathryn Trott, Christopher Jordan
We review an improved statistical model of extra-galactic point-source foregrounds first introduced in [Murray 2017], in the context of the Epoch of Reionization. This model extend…
An Improved Statistical Point-Source Foreground Model for the Epoch of Reionization
Steven G. Murray, Cathryn M. Trott, Christopher H. Jordan
We present a sophisticated statistical point-source foreground model for low-frequency radio Epoch of Reionization (EoR) experiments using the 21 cm neutral hydrogen emission line.…
