Scientists have detected two luminous radio bursts from a magnet in our galaxy as they got closer to discovering the source of the explosions.
Now scientists say they have found new explosions coming from the same magnetor. This should help explain further whether this is indeed a source of FRBs – and whether this process can power the explosions we have discovered from elsewhere in the universe.
Fast radio bursts are very few, very powerful bursts of radio energy that are sent through the universe. Although they are as low as a fraction of a millisecond, they can send out as much energy as the sun does in days – they are mostly unpredictable, but few have been found at a repeated time.
Astronomers hunted for an explanation for the eruption since 2007, when it was first discovered. Possible origins include everything from dying stars and black holes to alien technology.
That hunt has been mostly elusive, and it is still unclear what exactly causes the burst. But scientists looked very closely this year when they found out what one of the blasts is from inside our own galaxy, and tracked the source to a magnetic, or a neutron star with an incredibly powerful magnetic field did.
A few days after that discovery, researchers detected a very severe explosion coming from the same source, officially known as SGR1935 / 2154. It seems that there are similarities repeating other rapid radio bursts that were found before and outside our solar system.
Researchers hope that the discovery of the following eruptions, as well as an understanding of how active the source is, can help to show whether it is certainly similar to another FRB source outside of our galaxy Have come to us from
The researchers concluded that the magnet in our galaxy “makes a compelling case that there is (at least some) a link between the FRB and the magnet”. However, there are still some major questions, and scientists say that further monitoring of an object called SGR1935 + 2154 may help answer them.
They write that the explosions coming from the magnetors are “not an innocent analog” of FRBs that come to us from outside the galaxy. But this does not mean that those extragalactic FRBs cannot be explained by magnetists – the difference may be the result of the fact that the outside of our galaxy are smaller, and therefore brighter and more active.
A new paper published in the research is described Nature astronomy And the title of two bright radio bursts from ‘Magnetar SGR 1935 + 2154’.
