Mechanical and Optical Design of the HIRAX Radio Telescope
Benjamin R. B. Saliwanchik, Aaron Ewall-Wice, Devin Crichton +19
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a planned interferometric radio telescope array that will ultimately consist of 1024 close packed 6 m dishes tha…
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…
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…
Low-cost, Low-loss, Ultra-wideband Compact Feed for Interferometric Radio Telescopes
Vincent MacKay, Mark Lai, Peter Shmerko +3
We have developed, built, and tested a new feed design for interferometric radio telescopes with "large-, small-" designs. Those arrays require low-cost and low-complexity fe…
0.3-to-1.5-GHz LNA with Wideband Noise and Power Matching for Radio Astronomy
Mark Lai, Vincent MacKay, Dallas Wulf +2
This paper presents a low-noise amplifier (LNA) that was developed for a new radio telescope comprised of 512 parabolic dish antennas. The LNA closely interfaces to a custom-made a…
First Use of GPS Satellites for Beam Calibration of Radio Dish Telescopes
Sabrina Berger, Arianna Lasinski, Vincent MacKay +4
We present results from the first application of the Global Navigation Satellite System (GNSS; e.g., the Global Positioning System, GPS) for radio beam calibration using a commerci…
Complete Sampling of the Plane with Realistic Radio Arrays: Introducing the RULES Algorithm, with Application to 21 cm Foreground Wedge Removal
Vincent MacKay, Zhilei Xu, Ruby Byrne +1
We introduce the Radio-array Layout Engineering Strategy (RULES), an algorithm for designing radio arrays that achieve complete coverage of the plane, defined as, at mini…
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…
