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…

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…
