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…

Systematic assessment of the Hubble tension via Bayesian jackknife testing

Thomas Hughes, Michael J. Wilensky, Philip Bull

Statistically-significant differences in the value of the Hubble parameter are found depending on the measurement method that is used, a result known as the Hubble tension. A varie…

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…

Deep uGMRT observations for enhanced calibration of 21 cm arrays -- I. First image and source catalogue

Khandakar Md Asif Elahi, Samir Choudhuri, Nirupam Roy +3

Radio-interferometric arrays require very precise calibration to detect the Epoch of Reionization 21-cm signal. A remarkably complete and accurate sky model is therefore needed in…

High Dimensional Beam Inference II: Inference of a Perturbed HERA Beam from Simulated Visibility Data

Michael J. Wilensky, Philip Bull, Nicolas Fagnoni

Accurate beam modeling is important in many radio astronomy applications. In this paper, we focus on beam modeling for 21-cm intensity mapping experiments using radio interferomete…
