Astronomers have identified the source of a mysterious radio signal from space
Astronomers for the first time traced the relationship between magnetosome and fast radio bursts, nature, the origin of which is not reliably established. This is stated in the article on the website of the European space Agency (ESA).
The discovery was made by the space Observatory Integral, designed to explore objects in the hard x-ray and gamma range. At the end of April this year, the scanners Observatory observed the Magnetar SGR 1935 2154, discovered six years ago. Fixing the activity of the Magnetar, the researchers found that it radiated not only conventional x-rays but also radio waves.
Alert system established for Integral instantly notified about the outbreak of the Observatory around the world that has allowed scientists to examine its source. So, the canadian radio telescope for CHIME recorded a quick burst of high power, and the radio waves came from SGR 1935 2154.
"We've not seen before from the Magnetar radiation of radio waves, reminiscent of a quick burst," - said the study's lead author Sandro Mereghetti from the National Institute of astrophysics in Milan.
According to him, this is the first observed connection between magnetosome and fast radio bursts. "This is a really important discovery that will help us focus attention on the nature of these mysterious phenomena," he said.
Earlier, the astronomer Srinivas Kulkarni of the California Institute of technology told the portal, Science Alert, that astronomers first recorded in the milky Way galaxy, the burst of radio waves, accompanied by a flash of x-rays. Then, the researchers suggested that the source became burst of the Magnetar SGR 1935 2154.
Magnetar - a special class of neutron stars, which are associated with the most powerful and brightest explosions in the Universe. They possess the strongest magnetic fields.
Fast radio bursts - recorded by radio telescopes powerful periodic signals from a millisecond duration, coming from the depths of the Universe. They were first discovered in 2007, their nature remains unknown.
