An interferometric radio telescope, known as CHIME, at the Dominion Radio Astrophysical Observatory in British Columbia, Canada, built beginning in 2015 with science operations commencing in late September 2018. It receives radio waves from hydrogen in space at 400 to 800 MHz using four stationary cylindrical reflectors, and has become a leading instrument for detecting fast radio bursts, including the first known repeating fast radio burst with a regular periodicity.

Observing Band FAQs
Who built and runs the Canadian Hydrogen Intensity Mapping Experiment and who paid for it?
Scientists at four Canadian institutions built and run CHIME, funded mainly by the Canadian Foundation for Innovation with three provinces.
CHIME was built and is currently operated by scientists at the University of British Columbia, McGill University, the University of Toronto and the Dominion Radio Astrophysical Observatory, along with collaborating institutions throughout North America. Its principal funding came from the Canadian Foundation for Innovation, in partnership with the Provinces of British Columbia, Ontario and Quebec, and the project also receives funding from NSERC and CIFAR.
