Wonderful radio waves from the heart of the Milky Way


Strange radio waves are shown as the spiral earth approaches the sand from a distant glowing point in space.

Strange radio waves from non-hero sources

Radio emissions are common across the universe. They are made up of everything from planets and stars – objects to things like pulsars and black holes – cushions – and, of course, human technology. This week (October 12, 2021), astronomers say they have detected new and unusual radio waves, in contrast to what was found. Radio waves are coming from the center of our galaxy. And so far, scientists have not defined them.

The astronauts discovered variable signals using ASKAP radio telescopes in Australia. Radio emission behavior does not match any source of radio signal at source source source. It could be a New The kind of stellar thing, scientists said.

Ziteng Wang’s School of Physics at the University of Sydney hosts an international team of astrophysics specialists from Australia, Germany, the United States, Canada, South Africa, Spain and France. They published their peer-reviewed papers about interesting discoveries The Astrophysical Journal On the 12th of October.

Variable signal with unknown pattern

The source of the signals is disconnected ASKAP J173608.2-321635, but the astronauts do not actually have the source. It is located in the center of the center of our milk path. Wang said:

The light of the object […] Varies dramatically, with a factor of 100, and the signal switches on and off are seemingly random. We have never been such a thing.

Whatever it is, it’s extremely polar and osc heel, as Wang explained:

The strange property of this new signal is that it has very high polarization. This means its light osc radon is in the same direction, but it rotates with time.

Appear from invisible and back again

One of the extraordinary things about the extraordinary and extraordinary about the source is how it was found. Tara Murphy from the All Institute for Astronomy and School of Physics said:

We are surveying the sky with ASKAP to find unusual new objects with a project known as Variables and Slow Transients (VAST) between 2020 and 2021. Looking to the center of the galaxy, we found ASKAP J173608.2-321635, named PAN. Its maps. This thing was unique in that it started invisible, shined, disappeared, and reappeared. This behavior was unusual.

The astronauts detected these signals over a period of nine months in 2020. However, when astronomers tried to look at the source in visual light, using optical binoculars, they saw nothing. Parks radio telescopes also came up empty in Australia.

But then, in South Africa, the MeerKAT radio telescope, a set of telescopes, is a very sensitive, ڪيو Move it. The signal was there, even with a break DifferentGeneral Chat Chat Lounge Murphy explained the signal:

Fortunately, the signal returned, but we did find that the source behavior was dramatically different. The source disappeared within a day, though it stayed for weeks in our previous ASKAP observations.

What could be the source of wonderful radio waves?

Wang and his team denied that it could be a pulsar, a rapidly spinning neutron star that absorbs energy like energy from light energy:

At first we thought it might be a pulsar – a very kind of rotating dead star – or a star kind of star that emitted massive solar flames. But the signals of this new source do not match what we expect from these kinds of heavenly things.

Signals also show the objects that are produced from objects that are produced such as supernovae, rising stars and high-speed radio bristles (FRBs). These things are also variable, but sorry, there is no match to the newly discovered inequality.

However, there are some similarities with other mysterious sources near the nearby galactic center. Galactic Center Radio Transients (GCRT). David Kaplan at the University of Wisconsin-Milwaukee explained:

There are some parallels to what we have with an emergy-looking class of mysterious objects called CCTV and Galactic Center Radio Transients, which includes a ‘Cosmic Burger’.

While our new object, ASKAP J173608.2-321635, shares some proprietary GCRTs, there are differences as well. And we don’t really think these sources, however, so it adds to the mystery.

Step by step

Discovery is an astonishing mystery to scientists, and naturally, they want to understand it. So what comes next? Researchers plan to continue monitoring the signals as much as they can. In addition, they will receive, in this work, thanks to being a new powerful radio telescope. According to Murphy:

Within the next decade, the TransContinental Neon Square Square Era (SKA) radio telescope will come online. It will be able to access the daily sensitive maps of the sky. We hope that the power of this telescope will help us solve a mystery such as this latest discovery, but will also open up vast new sources of the universe so that it can be heard on the radio spectrum.

At the meantime, scientists will not keep up with current binoculars, hoping to find a clue. Everything that ig rays will provide interesting new insights into our universe.
