Radio waves to come from 8 billion light years away

Radio waves to come from 8 billion light years away

Scientists detected a fast radio waves burst named FRB 20220610A with the ASKAP Radio Telescope in Australia in June 2022. Astronomers then tried to identify the galaxy that was the source of the fast radio wave burst using the Very Large Telescope (VLT) at the European Southern Observatory (ESO) in Chile.

As a result, it was determined that the source of the fast radio wave burst named FRB 20220610A was a galaxy 8 billion light years away. FRB 20220610A is the most distant fast radio wave burst detected so far. It is estimated that during FRB 20220610A, more energy was emitted in a very short time than the total radiation energy emitted by the Sun in 30 years.

Fast radio wave bursts are electromagnetic light emissions at radio wavelengths that last for short periods of time, such as milliseconds. Fast bursts of radio waves move within and between galaxies. In this process, low-frequency radio waves slow down more than high-frequency radio waves as they pass through hot gases.

In this way, it may become possible to obtain information about the existence of substances between galaxies that cannot be detected by other methods. So fast bursts of radio waves could help understand the structure of the universe.
