The Role of the Instrumental Response in 21 cm EoR Power Spectrum Gridding Analyses

Nichole Barry, Aman Chokshi

Reconstruction of the sky brightness measured by radio interferometers is typically achieved through gridding techniques, or histograms in spatial Fourier space. For Epoch of Reion…

The FHD Polarized Imaging Pipeline: A New Approach to Widefield Interferometric Polarimetry

Ruby Byrne, Miguel F. Morales, Bryna Hazelton +2

We describe a new polarized imaging pipeline implemented in the FHD software package. The pipeline is based on the optimal mapmaking imaging approach and performs horizon-to-horizo…

Quantifying Excess Power from Radio Frequency Interference in Epoch of Reionization Measurements

Michael J. Wilensky, Nichole Barry, Miguel F. Morales +2

We quantify the effect of radio frequency interference (RFI) on measurements of the 21-cm power spectrum during the Epoch of Reionization (EoR). Specifically, we investigate how th…

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…
