First Season MWA Phase II EoR Power Spectrum Results at Redshift 7

Understand

The compact configuration of Phase II of the Murchison Widefield Array (MWA) consists of both a redundant subarray and pseudo-random baselines, offering unique opportunities to perform sky-model and redundant interferometric calibration.

• The highly redundant hexagonal cores give improved power spectrum sensitivity.
• In this paper, we present the analysis of nearly 40 hours of data targeting one of the MWA's EoR fields observed in 2016.
• We use both improved analysis techniques presented in Barry et al.
