Determining Ideal Fields for Epoch of Reionisation Science Using the 21 cm Line
E. Jong, C. Trott, C. D. Nunhokee +1
The upcoming Square Kilometre Array Low Frequency (SKA-Low) interferometer will have the required sensitivity to detect the 21 cm line from neutral hydrogen during the Epoch of Rei…
System design and calibration of SITARA -- a global 21 cm short spacing interferometer prototype
Jishnu N. Thekkeppattu, Benjamin McKinley, Cathryn M. Trott +2
Global 21-cm experiments require exquisitely precise calibration of the measurement systems in order to separate the weak 21-cm signal from Galactic and extragalactic foregrounds a…
Imaging the Southern Sky at 159MHz using Spherical Harmonics with the Engineering Development Array 2
Michael A. Kriele, Randall B. Wayth, Mark J. Bentum +2
One of the major priorities of international radio astronomy is to study the early universe through the detection of the 21 cm HI line from the epoch of reionisation (EoR). Due to…
Simulations of ionospheric refraction on radio interferometric data
J. Kariuki Chege, C. H. Jordan, C. Lynch +2
The Epoch of Reionisation (EoR) is the period within which the neutral universe transitioned to an ionised one. This period remains unobserved using low-frequency radio interferome…
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…
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…
