Overview of the Canadian Hydrogen Observatory and Radio Transient Detector (CHORD) Project
The CHORD Collaboration, Kevin Bandura, Leonid Belostotski +49
The Canadian Hydrogen Observatory and Radio-transient Detector (CHORD) is a next-generation wideband radio interferometer currently being constructed and commissioned at the Domini…
Observations of the Cosmic Dawn and Epoch of Reionization with the SKAO: Observational Lessons Learned from Precursors and Pathfinder Instruments
Eloy de Lera Acedo, James Aguirre, Dominic Anstey +34
This chapter summarizes the observational lessons learned after two decades of observations of the Cosmic Dawn (CD) and Epoch of Reionization (EoR) with SKAO pathfinders and precur…
A spatial filter for mitigating radio interference and its application to CHIME/FRB Outriggers
Shion Andrew, Juan Mena-Parra, Haochen Wang +16
The sensitivity of radio telescopes is becoming increasingly limited by the presence of radio frequency interference (RFI), which will worsen as the radio spectrum becomes more cro…
Correlation Calibration: A Hybrid Calibration Technique for Radio Interferometric Arrays
Robert Pascua, Jonathan Sievers, Adrian Liu
Calibrating out per-antenna signal chain effects is an essential step in analyzing radio interferometric data. For drift-scanning arrays, robustly calibrating the data is especiall…
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…
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…
