The Impact of Tandem Redundant/Sky-Based Calibration in MWA Phase II Data Analysis
Zheng Zhang, Jonathan C. Pober, Wenyang Li +26
Precise instrumental calibration is of crucial importance to 21-cm cosmology experiments. The Murchison Widefield Array's (MWA) Phase II compact configuration offers us opportuniti…
Exploring reionisation and high-z galaxy observables with recent multi-redshift MWA upper limits on the 21-cm signal
Bradley Greig, Cathryn M. Trott, Nichole Barry +4
We use the latest multi-redshift () upper limits on the 21-cm signal from the Murchison Widefield Array (MWA) to explore astrophysical models which are inconsistent with…
Modelling and peeling extended sources with shapelets: a Fornax A case study
J. L. B. Line, D. A. Mitchell, B. Pindor +6
To make a power spectrum (PS) detection of the 21 cm signal from the Epoch of Reionisation (EoR), one must avoid/subtract bright foreground sources. Sources such as Fornax A presen…
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).…
