Scientists have discovered two types of sources of fast radio bursts, including “from aliens”

Astronomers at the Massachusetts Institute of Technology have recorded hundreds of mysterious fast radio bursts and determined that they have two types of sources.

Over the course of a year, the Canadian Radio Wave Observatory CHIME has recorded over five hundred fast radio bursts (FRBs), mysterious short radio signals of enormous power.

Fast radio bursts, from the English. Fast Radio Bursts – single radio pulses recorded by radio telescopes with a duration of several milliseconds

Before CHIME was built, we knew about a hundred FRB bursts. In just a year of observations, we have discovered several hundred sources of single and repeated radio signals, whose study will allow us to clarify the nature and physical mechanisms of the formation of these flares.

During the work, the authors compiled a catalog of fast radbursts: it significantly expands the current library of known FRBs and contains information about their properties.

As a result, all recorded bursts were divided into two groups: single and repeated. 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.
