To date, scientists do not know the cause of repeated bursts, but a similarity has been found with the activity of magnets – a type of neutron star with a very strong magnetic field.
Astronomers at Swinburne University of Technology in Australia have observed mysterious and almost unnoticed radio bursts of FRB 171019.
According to the Science Alert website, scientists looked for signs of repetition of 20 FRB (rapid radio bursts) using the ASKAP Australian Square Kilometer Array Pathfinder, and they spent about 12,000 hours. Because the research was not successful, researchers began monitoring FRB 171019 using the Green Bank radio telescope in the United States and the Observatory wireless telescope in Australia.
The information Green Bank received showed two weak signals. This indicates that repeated radio bursts occur more than previously thought, and that many individual bursts are already associated with them, only their signals outside the detection range of these instruments. Hidden signals FRB 171019 590 times weaker than ASKAP burst.
To date, scientists do not know the cause of repeated bursts, but a similarity has been found with the activity of magnets – a type of neutron star with a very strong magnetic field. The researchers believe that the results of the work will help explain the phenomenon of rapid radio bursts.
The duration of a rapid radio pulse lasts several milliseconds and is accompanied by the release of a large amount of energy – such as that which is emitted by the sun in tens of thousands of years.
