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…
MWA Tied-Array Processing I: Calibration and Beamformation
S. M. Ord, S. E. Tremblay, S. J. McSweeney +5
The Murchison Widefield Array is a low-frequency Square Kilometre Array precursor located at the Murchison Radio-astronomy Observatory in Western Australia. Primarily designed as a…
Assessment of ionospheric activity tolerances for Epoch of Reionisation science with the Murchison Widefield Array
Cathryn M. Trott, C. H. Jordan, S. G. Murray +20
Structure imprinted in foreground extragalactic point sources by ionospheric refraction has the potential to contaminate Epoch of Reionisation (EoR) power spectra of the 21~cm emis…
Comparing Redundant and Sky Model Based Interferometric Calibration: A First Look with Phase II of the MWA
W. Li, J. C. Pober, B. J. Hazelton +53
Interferometric arrays seeking to measure the 21 cm signal from the Epoch of Reionization must contend with overwhelmingly bright emission from foreground sources. Accurate recover…
The challenges of low-frequency radio polarimetry: lessons from the Murchison Widefield Array
Emil Lenc, C. S. Anderson, N. Barry +26
We present techniques developed to calibrate and correct Murchison Widefield Array (MWA) low frequency (72-300 MHz) radio observations for polarimetry. The extremely wide field-of-…
