CHIME collaboration of scientists involved in the search for fast radio bursts, reported on the re-registration signals from a source FRB 180814.J0422+73. Until now it was known only about one recurring source of fast radio bursts. Article of astrophysicists published in the journal Nature.
Quick radar pulse lasts for several milliseconds and emits into space huge amounts of energy — what the Sun emits within a few tens of thousands of years. One hypothesis suggests that this phenomenon is due to the activities of alien civilizations. Some scientists say that such bursts may result from catastrophic events such as supernovae. However, one of the sources — FRB 121102, which is located in the dwarf galaxy in three billion light years from Earth, — emits a repeating radio signals which scientists have not yet found a reliable explanation.
Repetitive fast radio bursts cannot be explained by catastrophic events, however so far not found other sources that are similar to the FRB 121102, despite a thorough search, making them extremely rare. In July and August of 2018 interferometric radio telescope for CHIME (eng. Canadian Hydrogen Intensity Mapping Experiment) registered six fast radio bursts emanating from the same source — FRB 180814.J0422+73. According to calculations, this facility is located about 1.3 billion light years from Earth.
Signals in its frequency structure and spectral characteristics resembled the signals from the FRB 121102, indicating a similar mechanism of their formation and the same nature of the source.
