Mitigating Internal Instrument Coupling II: A Method Demonstration with the Hydrogen Epoch of Reionization Array

Nicholas S. Kern, Aaron R. Parsons, Joshua S. Dillon +63

We present a study of internal reflection and cross coupling systematics in Phase I of the Hydrogen Epoch of Reionization Array (HERA). In a companion paper, we outlined the mathem…

Mitigating Internal Instrument Coupling for 21 cm Cosmology I: Temporal and Spectral Modeling in Simulations

Nicholas S. Kern, Aaron R. Parsons, Joshua S. Dillon +3

We study the behavior of internal signal chain reflections and antenna cross coupling as systematics for 21 cm cosmological surveys. We outline the mathematics for how these system…

Absolute Calibration Strategies for the Hydrogen Epoch of Reionization Array and Their Impact on the 21 cm Power Spectrum

Nicholas S. Kern, Joshua S. Dillon, Aaron R. Parsons +69

We discuss absolute calibration strategies for Phase I of the Hydrogen Epoch of Reionization Array (HERA), which aims to measure the cosmological 21 cm signal from the Epoch of Rei…

A simplified, lossless re-analysis of PAPER-64

Matthew Kolopanis, Daniel C. Jacobs, Carina Cheng +20

We present limits on the 21cm power spectrum from the Epoch of Reionization (EoR) using data from the 64 antenna configuration of the Donald C. Backer Precision Array for Probing t…

Understanding the HERA Phase I receiver system with simulations and its impact on the detectability of the EoR delay power spectrum

Nicolas Fagnoni, Eloy de Lera Acedo, David R. DeBoer +67

The detection of the Epoch of Reionization (EoR) delay power spectrum using a "foreground avoidance method" highly depends on the instrument chromaticity. The systematic effects in…
