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…
Calibration database for the Murchison Widefield Array All-Sky Virtual Observatory
M. Sokolowski, C. H. Jordan, G. Sleap +11
We present a calibration component for the Murchison Widefield Array All-Sky Virtual Observatory (MWA ASVO) utilising a newly developed PostgreSQL database of calibration solutions…
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…
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…
