The strongest rapid radio impulse discovered telescopes throughout North America

Nearly two decades ago, astronomers have discovered a very strong flash of radio waves known as Radio Radies (FRBS) from behind our galaxy-and they did not have the slightest idea of ​​where they came. Now, a team of scientists discovered the brightest FRB and finally set its origin into a nearby galaxy.

Researchers have long suspected that FRBS is the result of very active and violent events, such as clashes between neutron stars. But although they can generate more energy in an explosion of more than our sun in one year, they went in less time than it takes for a day. Due to their transient nature, astronomers have not been able to locate their place so far.

“We were discovering a lot of FRBS, but we had only raw information about the place where they were in the sky,” said Brian Jinsler, the co -author of the study and dean of the Department of Science at the University of California in Santa Cruz. statement. “It was like talking to someone on the phone and not knowing the city or the country they are calling.”

He added to him: “Now we not only know their exact address, but it is the room of their home where they are in contact.”

The brightness of the rush and the proximity of the researchers give new evidence not only in the place where the flash arose, but also the reason for this. The results were published in Astronomical physical magazine letters.

Radio goats

Astronomers have discovered this bright FRB exceptionally, and it is officially referred to as the FRB 20250316A, in March of the Great Dipper direction using the harmony radio telescope in British Columbia. They refer to the flash called “RBFLOAT” for “Radio Bristing Flash in all times.” Flash has produced more energy in a few milliliters of our sun in four days.

Astronomers identified the flash thanks to the experience of the Canadian Hydrogen Maps (Chime), a large radio telescope in British Columbia, and the newly completed “Outrigger” telescope group, which extends across North America from BC to West Virginia. This wide network, which was broadcast a few months ago, is sensitive enough to discover the bright radio flash.

While many FRBS are repeated, they are beating several times within several months, RBFloat has emitted from all its capacity in only one explosion. In hundreds of hours after taking into account this for the first time, astronomers did not discover another explosion from the source.

Astronomers follow this explosion to a 45-year-old area only-on an equal foot from the middle group of stars-on the outskirts of a galaxy, about 130 million light years. RBFLOat event along a spiral arm of that galaxy, which is spread with many areas that make up stars. The explosion arose near these areas, but not at home, one of these areas, according to the study.

“It is striking that after only two months after two months of the full Outrigger hemorros, we discovered a very bright FRB in a galaxy in our cosmic life,” said Wayne Fei Fung, a great author of the study and professor of physics and astronomy at the University of North Western. statement.

Solve the cosmic puzzle

Next, using data from Keck Cosmic Web Image, a spectral tool on Keck II 10 meters in Hawaii, researchers enabled the study of RBFLOAT. This included the physical properties of the invasive environment that FRB resulted in, including the rate of stars production in the galaxy, the total amount of gas in anywhere in the galaxy, and its density.

But it is still an exact mystery of the flash. The team is suspected that it was produced by magnets – a very magnetic neutron star behind it after the Supernova star.

“Sizon weapons are usually sites to form the continuous stars, which support the idea that they came from a magnet. Using a very sensitive MMT image, we were able to enlarge further and found that FRB is already outside the nearest masses to form stars. statement.

Dong added: “This may indicate that the predecessor singer has been taken from his birth site or that he was born directly on the FRB site and away from the center of blocks.”

With the full Outriggers, astronomers expect to determine more FRBS every year, and they may approach us to understand their origins.

“This result is a turning point,” said the author of the study, Amanda Cook, a post -PhD researcher at McGill University, in A. statement. “Instead of just discovering these mysterious gifts, we can now see exactly where it comes. The door opens to discover whether it is caused by the stars that die or strange magnetic things or something we haven’t thought about yet.”
