During the year of its operation, the Canadian radio wave observatory CHIME recorded more than five hundred fast
Fast radio bursts, from English. Fast Radio Bursts — single radio pulses with a duration of several milliseconds recorded by radio telescopes
Before CHIME was built, we knew about the existenceapproximately one hundred FRB bursts. In just a year of observations, we discovered several hundred sources of single and repeating radio signals, whose study will allow us to clarify the nature and physical mechanisms of the formation of these flares.

During their work, the authors compiled a catalog of fast rad bursts: it significantly expands the current library of known FRBs and contains information about their properties.
As a result, all recorded burstsdivided into two groups: single and repetitive. Among the recently discovered FRBs, scientists identified 18 sources that exploded repeatedly, the rest were isolated.
Astronomers found that repetitive signals last slightly longer, and their radiation was concentrated in a narrower part of the spectrum.
