First Results from HERA Phase II

The HERA Collaboration, Zuhra Abdurashidova, Tyrone Adams +83

We report the first upper limits on the power spectrum of 21-cm fluctuations during the Epoch of Reionization and Cosmic Dawn from Phase II of the Hydrogen Epoch of Reionization Ar…

Exploring One-point Statistics in HERA Phase I Data: Effects of Foregrounds and Systematics on Measuring One-Point Statistics

Honggeun Kim, Jacqueline N. Hewitt, Nicholas S. Kern +61

Measuring one-point statistics in redshifted 21 cm intensity maps offers an opportunity to explore non-Gaussian features of the early universe. We assess the impact of instrumental…

fftvis: A Non-Uniform Fast Fourier Transform Based Interferometric Visibility Simulator

Tyler A. Cox, Steven G. Murray, Aaron R. Parsons +6

The detection and characterization of the 21cm signal from the Epoch of Reionization (EoR) demands extraordinary precision in radio interferometric observations and analysis. For m…

Impacts and Statistical Mitigation of Missing Data on the 21cm Power Spectrum: A Case Study with the Hydrogen Epoch of Reionization Array

Kai-Feng Chen, Michael J. Wilensky, Adrian Liu +66

The precise characterization and mitigation of systematic effects is one of the biggest roadblocks impeding the detection of the fluctuations of cosmological 21cm signals. Missing…

A Generalized Method for Characterizing 21-cm Power Spectrum Signal Loss from Temporal Filtering of Drift-scanning Visibilities

Robert Pascua, Zachary E. Martinot, Adrian Liu +7

A successful detection of the cosmological 21-cm signal from intensity mapping experiments (for example, during the Epoch of Reioinization or Cosmic Dawn) is contingent on the supp…

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…
