The energy explosions emanating from deep in space are of strange origin

Fast radio bursts (FRB) are one of the most mysterious and compelling phenomena with energy coming from deep in the universe.

Fast radio bursts (fast radio burst or FRB) are one of the most attractive and attractive with energy coming from deep in the universe.

Fast radio waves or FRBs are strong pulses of radio waves lasting only a few milliseconds, which can produce a fraction of a second more energy than the Sun for several hours, days or weeks. Scientists wrote in the study that FRBs were only discovered in 2007, and while researchers have discovered about 20 FRBs in the past decade, they estimate possible flashes. up to 10,000 times a day across the whole sky.

The origin of FRB is still a mystery because their short nature makes it difficult for scientists to determine where they come from. Previous studies suggest that FRB may be due to the stinking of black holes or collisions between neutron stars.

However, in 2016, scientists discovered a fast radio wave explosion called FRB 121102 that could release many other explosions. " This is a fast explosion that has been repeated many times," research co-author Jason Hessels, an astronomer at the University of Amsterdam, told Space.

Mr. Hessels judged that FRB 121102 could explode several times to show that it did not originate from a geological event."An important question in this area is whether this repetitive radio source is fundamentally different from all other ambiguous sources," the scientist said.

To learn more about this FRB, scientists used the Arecibo Observatory in Puerto Rico and the Green Bank Telescope in West Virginia to analyze data on 16 explosions. FRB 121102 is located in a star-forming region of a dwarf galaxy about 3 billion light-years from Earth, Mr. Hessels said. Because astronomers can see FRB 121102 from such a long distance, the energy in a millisecond of each of these explosions must be the same as the Sun's energy is transmitted throughout the day.

These findings stem from a study focused on examining one of the fast radio wave bursts known as FRB 121102. Finally, scientists have understood how the message is polarized. They discovered FRB 121102 it came from a strange source, such as a giant.

In this study, the researchers focused on a characteristic of radio waves called polarization. This property occurs because all light waves, including radio waves, can ripple up and down, left, right or at any corner in the middle. Magnetic radio waves FRB 121102 has a short time and polarity (most radio waves spread in the same direction), similar to emission from energetic neutron stars previously seen in Milky Way, Andrew Seymour, author of the study and scientist at the Ionosphere National Astronomical Center at Arecibo Observatory, said in the statement.

When radio waves pass through an attracted plasma frequency, or the cloud of charged particles, the direction in which they polarize can be twisted, an effect called Faraday rotation. Hessels and his colleagues found that the radio explosions of FRB 121102 were twisted more than 500 times compared to results from any FRB to date.

Mr. Hessels said: "I couldn't believe my eyes when I first saw the data. Faraday's extreme rotation is very rare."

This extreme twist shows that the FRB 121102 explosions go through an extremely hot plasma frequency, with a very strong magnetic field. According to the researchers, these plasma frequencies could exist near the black hole, possibly a black hole more than 10,000 times the mass of the Sun or the remnants of the supernova.

Researcher Hessels said: "It is myself and many others who want to know whether this radio wave explosion is single or multi-physical. There are a large number of telescopes that will appear in a few years. Come, promise research support, discover more to answer these questions. "

Although until now, no one can be certain about aliens, but many astronomers still focus on finding extraterrestrial intelligence. Dr. Vishal Gajjar, one of the scientists involved in the research project on FRB 121102, said: "We cannot completely eliminate the alien hypothesis for FRB explosions in general."
