CHIME and its 3 Outriggers

The Canadian Hydrogen Intensity Mapping Experiment (CHIME) detects fast radio bursts: brief pulses of radio emission from distant galaxies, and its Outrigger telescopes in British Columbia, California and West Virginia pinpoint where they come from. This site provides the CHIME/FRB collaboration’s published catalogs and data products for research and public use.
