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…
Development of a High Throughput Cloud-Based Data Pipeline for 21 cm Cosmology
Ruby Byrne, Daniel Jacobs
We present a case study of a cloud-based computational workflow for processing large astronomical data sets from the Murchison Widefield Array (MWA) cosmology experiment. Cloud com…
A Unified Calibration Framework for 21 cm Cosmology
Ruby Byrne, Miguel F. Morales, Bryna Hazelton +1
Calibration precision is currently a limiting systematic in 21 cm cosmology experiments. While there are innumerable calibration approaches, most can be categorized as either `sky-…
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…
Deep multi-redshift limits on Epoch of Reionisation 21cm Power Spectra from Four Seasons of Murchison Widefield Array Observations
Cathryn M. Trott, C. H. Jordan, S. Midgley +33
We compute the spherically-averaged power spectrum from four seasons of data obtained for the Epoch of Reionisation (EoR) project observed with the Murchison Widefield Array (MWA).…
