Over 500 new FRBs detected in single year due to CHIME telescope

Fast radio bursts, or FRBs, blaze for a few milliseconds before vanishing without a trace. Their origins are unknown, and their appearance is unpredictable. In the decade following their discovery in 2007, only 140 FRBs had been seen. Now, thanks to the launch of a large stationary telescope in the interior of British Columbia in 2018, the number of new FRBs detected has almost quadrupled - for a total of 535. Moreover, the Canadian Hydrogen Intensity Mapping Experiment (CHIME/FRB), a McGill-led inter-university collaboration, has put together the first CHIME/FRB catalogue, which will be presented this week at the American Astronomical Society Meeting. CHIME is unique in that it observes the entire Northern sky once every day. Signals from over a thousand antennas are digitally processed in real time to enable high sensitivity measurements over a wide range of frequencies.
