LRP 2020 Whitepaper: The Canadian Hydrogen Observatory and Radio-transient Detector (CHORD)

Abstract

The Canadian Hydrogen Observatory and Radio-transient Detector (CHORD) is a next-generation radio telescope, proposed for construction to start immediately. CHORD is a pan-Canadian project, designed to work with and build on the success of the Canadian Hydrogen Intensity Mapping Experiment (CHIME). It is an ultra-wideband, "large-N, small-D" telescope, consisting of a central array of 512x6-m dishes, supported by a pair of distant outrigger stations, each equipped with CHIME-like cylinders and a 64-dish array. CHORD will measure the distribution of matter over a huge swath of the Universe, detect and localize tens of thousands of Fast RadioBursts (FRBs), and undertake cutting-edge measurements of fundamental physics.
