Inverting and Up-channelizing Critically-Sampled Polyphase Filter Banks
Stephen Fay, Mohan Agrawal, Hsin Cynthia Chiang +3
Polyphase filter banks (PFBs) are widely used to channelize digitized time-domain data in real time. However, applications such as radio astronomy often require higher spectral res…
Dish Assembly Precision for HIRAX
Jennifer Studer, Devin Crichton, Alexandre Refregier +16
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a radio interferometer array that is being deployed at the South African Radio Astronomy Observatory (SARAO) Squ…
Continuous Ultra-Low-Frequency Solar Radio Monitoring with ALBATROS from the High Arctic
Aman Chokshi, Mohan Agrawal, Christopher Barbarie +18
In the Canadian High Arctic, nearly five months of continuous daylight enable uninterrupted low-frequency solar monitoring. We present the first solar science results from the Arra…
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…
Primary Beam Chromaticity in HIRAX: I. Characterization from Simulations and Power Spectrum Implications
Ajith Sampath, Devin Crichton, Kavilan Moodley +15
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is an upcoming radio interferometric telescope designed to constrain dark energy through the 21cm intensity mapping…
Drone-Based Antenna Beam Calibration in the High Arctic
Lawrence Herman, Christopher Barbarie, Will Tyndall +17
Precision calibration is a critical requirement for future ultra-low-frequency observations of the early universe. The Array of Long Baseline Antennas for Taking Radio Observations…
HIRAX: A Probe of Dark Energy and Radio Transients
L. B. Newburgh, K. Bandura, M. A. Bucher +33
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a new 400-800MHz radio interferometer under development for deployment in South Africa. HIRAX will comprise 1024…
