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…

The All-Sky SignAl Short-Spacing INterferometer (ASSASSIN) I: Global sky measurements with the Engineering Development Array-2

B. McKinley, C. M. Trott, M. Sokolowski +5

Aiming to fill a crucial gap in our observational knowledge of the early Universe, experiments around the world continue to attempt to verify the claimed detection of the redshifte…

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…

The Impact of Realistic Foreground and Instrument Models on 21cm Epoch of Reionization Experiments

Ainulnabilah Nasirudin, Steven Murray, Cathryn Trott +3

Predictions for the ability of 21-cm interferometric experiments to discriminate Epoch of Reionization (EoR) signal models are typically limited by the simplicity of data models, w…

The bispectrum and 21cm foregrounds during the Epoch of Reionization

Catherine A Watkinson, Cathryn M Trott, Ian Hothi

Numerous studies have established the theoretical potential of the 21cm bispectrum to boost our understanding of the Epoch of Reionization (EoR), and therefore early generation of…
