CHIME radio telescope Radio Astrophysical Observatory Dominion (British Columbia, Canada) has recorded more than half a thousand fast radio bursts in its first year of operation. This was reported by researchers from Canada and the United States at the 238th meeting of the American Astronomical Community.
Fast Radio Bursts (FRB) – a mysterious cosmic phenomenon, which is a powerful rapid pulse in the radio spectrum of electromagnetic radiation. In the fraction of a second that lasts FRB, energy is thrown into space, which the Sun could produce in tens of thousands of years. What generates FRBs is unknown, but there are various hypotheses about it.
Since 2007, when astronomers recorded the first quick radio burst in the history of science, there have been recorded no more than 140 FRB. It is believed that to notice another burst is a great astronomical good fortune.
But now, when in Canada launched radio telescope CHIME, registration of FRB can become commonplace. This is confirmed by the fact that only in the first year of the Canadian Hydrogen Intensity Mapping Experiment (CHIME), scientists managed to register 535 fast radio bursts. Of these, 18 turned out to be repetitive. Pulses of the latter, by the way, slightly differ from pulses of single FRB – they last a little longer, and their radio emission is more focused.
