The Correlation Calibration of PAPER-64 data

Tamirat G. Gogo, Yin-Zhe Ma, Piyanat Kittiwisit +21

Observation of redshifted 21-cm signal from the Epoch of Reionization (EoR) is challenging due to contamination from the bright foreground sources that exceed the signal by several…

The Hydrogen Intensity and Real-time Analysis eXperiment: 256-Element Array Status and Overview

Devin Crichton, Moumita Aich, Adam Amara +97

The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a radio interferometer array currently in development, with an initial 256-element array to be deployed at the S…

Automated Detection of Antenna Malfunctions in Large-N Interferometers: A Case Study with the Hydrogen Epoch of Reionization Array

Dara Storer, Joshua S. Dillon, Daniel C. Jacobs +75

We present a framework for identifying and flagging malfunctioning antennas in large radio interferometers. We outline two distinct categories of metrics designed to detect outlier…

First Results from HERA Phase I: Upper Limits on the Epoch of Reionization 21 cm Power Spectrum

The HERA Collaboration, Zara Abdurashidova, James E. Aguirre +74

We report upper-limits on the Epoch of Reionization (EoR) 21 cm power spectrum at redshifts 7.9 and 10.4 with 18 nights of data ( hours of integration) from Phase I of the…

HERA Phase I Limits on the Cosmic 21-cm Signal: Constraints on Astrophysics and Cosmology During the Epoch of Reionization

The HERA Collaboration, Zara Abdurashidova, James E. Aguirre +81

Recently, the Hydrogen Epoch of Reionization Array (HERA) collaboration has produced the experiment's first upper limits on the power spectrum of 21-cm fluctuations at z~8 and 10.…

Validation of the HERA Phase I Epoch of Reionization 21 cm Power Spectrum Software Pipeline

James E. Aguirre, Steven G. Murray, Robert Pascua +73

We describe the validation of the HERA Phase I software pipeline by a series of modular tests, building up to an end-to-end simulation. The philosophy of this approach is to valida…
