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…

XQR-30: the ultimate XSHOOTER quasar sample at the reionization epoch

Valentina D'Odorico, E. Banados, G. D. Becker +46

The final phase of the reionization process can be probed by rest-frame UV absorption spectra of quasars at z>6, shedding light on the properties of the diffuse intergalactic mediu…

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).…

Improving the Epoch of Reionization Power Spectrum Results from Murchison Widefield Array Season 1 Observations

N. Barry, M. Wilensky, C. M. Trott +27

Measurements of 21 cm Epoch of Reionization (EoR) structure are subject to systematics originating from both the analysis and the observation conditions. Using 2013 data from the M…

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 .…

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)…

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…
