Bayesian jackknife tests with a small number of subsets: Application to HERA 21cm power spectrum upper limits

Michael J. Wilensky, Fraser Kennedy, Philip Bull +2

We present a Bayesian jackknife test for assessing the probability that a data set contains biased subsets, and, if so, which of the subsets are likely to be biased. The test can b…

Characterization Of Inpaint Residuals In Interferometric Measurements of the Epoch Of Reionization

Michael Pagano, Jing Liu, Adrian Liu +75

Radio Frequency Interference (RFI) is one of the systematic challenges preventing 21cm interferometric instruments from detecting the Epoch of Reionization. To mitigate the effects…

Improved Constraints on the 21 cm EoR Power Spectrum and the X-Ray Heating of the IGM with HERA Phase I Observations

The HERA Collaboration, Zara Abdurashidova, Tyrone Adams +92

We report the most sensitive upper limits to date on the 21 cm epoch of reionization power spectrum using 94 nights of observing with Phase I of the Hydrogen Epoch of Reionization…

Impact of instrument and data characteristics in the interferometric reconstruction of the 21 cm power spectrum

Adélie Gorce, Samskruthi Ganjam, Adrian Liu +75

Combining the visibilities measured by an interferometer to form a cosmological power spectrum is a complicated process. In a delay-based analysis, the mapping between instrumental…

Direct Optimal Mapping for 21cm Cosmology: A Demonstration with the Hydrogen Epoch of Reionization Array

Zhilei Xu, Jacqueline N. Hewitt, Kai-Feng Chen +78

Motivated by the desire for wide-field images with well-defined statistical properties for 21cm cosmology, we implement an optimal mapping pipeline that computes a maximum likeliho…
