The powerful radio signal found in our galaxy is officially the fastest radio hit


Astrophysicists have discovered for the first time the explosion of cosmic radio waves inside our galaxy and identified its source, revealing a new mystery in the universe, according to research published on Wednesday.

The emergence of powerful fast radio rates (FRBs) – the intense glare of radio emissions that last only a few milliseconds – has taken scientists by surprise since they were discovered a decade ago.

It is usually extra galactic, meaning it originates outside our galaxy, but on April 28 this year, multiple telescopes found a bright FRB from the same area of ​​our galaxy.

Importantly, they were also able to cut down the source: galactic magnet ar SGR 1935 + 2154.

Magnetars, the young neutron stars that are the most magnetic objects in the universe, have long been the main suspects in the search for the source of these radio explosions.

But this discovery marks the first time that astronomers have been able to detect a direct signal on a magnet.

Christopher Bochenek, who was part of the Survey for Transient Astronomical Radio Emission 2 (STARE2) eruption team in the US, said that a magnet emits as much energy as the sun’s radio waves in about 30 milliseconds per second.

He said the explosion was “so bright” that theoretically if you had a recording of the raw data of your mobile phone’s 4G LTE receiver and what you should see, “you probably got this signal that came around the Galaxy” phone data.

This energy was comparable to the FRB outside the galaxy, he said, strengthening the case for magnets to be the source of most extra-galactic explosions.

There may be as many as 10,000 FRBs per day, but these high-energy surgeons were only found in 2007.

They have since been the subject of intense debate, despite small steps for astronomers to excite their origins.

One problem is that it is difficult to pinpoint a transient flu without knowing where to look.

Their basic theories range from atrocious events such as supernovae to neutron stars, which are fragments of super-Gaense stars formed after the star’s gravitational collapse.

There are even more foreign revelations – extra-terrestrial signs – discounted by astronomers.

‘Key Puzzle’

The latest discovery, which was published in three papers in the journal Nature, Was created by observations from space and ground-based telescopes.

Both STARE2 and the Canadian Hydrogen Intensity Mapping Experiment (CHIME) detected the flame and attributed it to magnets.

Later that day, this area of ​​the sky was spotted in China by the highly sensitive Five Hundred Meter Aperture Spherical Telescope (FAST).

According to Bing Zhang, a researcher at the University of Nevada, astronomers there were already watching the magnet, which had entered the “active phase” and was firing from X-ray and gamma ray explosions. Search.

Fast did not find the FRB himself, but received several X-ray shots from the magnetar, he said in a press briefing, raising new questions about why only one explosion was linked to the FRB.

Inside Nature Amanda Weltman and Anthony Watters, commentators at Cape Town University’s High Energy Physics, Cosmology and Astrophysics Theory Group, said the FRB’s link to a magnet “probably solves a major puzzle.”

But they said the findings also open up a series of new questions, including which method is generated, “Such a bright, yet rare, ray-ray explosion occurs with an X-ray replica?”

“One promising possibility is that the flames of the magnet collide with the surrounding medium and produce a shock wave there,” he wrote, adding that these findings highlight the need for international collaboration in astronomy and the observation of a variety of signals.
