Astronomers find unknown radio signals from the center of the Milky Way Science and Ecology | DW

The team of astronomers detected abnormal radio signals coming in the direction of the center of the Milky Way and said they did not match the known radio source format. An article published on Tuesday (10.12.2021) in the Special Magazine Astrophysical Journal.

“We have never seen anything like this before. The strange property of this new signal is that it has a very high polarity,” said Zideng Wang, a student at the University of Sydney and a teacher’s principal. Australia.

This means that, according to the article, its light “oscillates only in one direction but rotates with that direction over time” and “the brightness of the object also varies considerably, 100 factor, and the signal appears inconsistent when on and off,” the post added.

A new type of objects in space?

The technical name given to the waves was ASKAP J173608.2-321635, and the signal was detected six times between January and September 2020 and then reappeared on February 7 this year.

“ASKAP J173608.2-321635 may represent part of a new type of material discovered through radio imaging studies,” Wang added.

What can create this event?

The center of the galaxy’s orbit has a large black hole at its center, and the region contains large dense stars, including red giants, super giants, and numerous sources of very hot gases and radio signals.

Many types of stars emit variable lights over the entire range of the electromagnetic spectrum, and the study of variable or unstable objects with advances in radio astronomy is a vast field for study.

“At first we thought it might be a pulsar – a very dense, rotating type of dead star – or a type of star that emits a large amount of sunlight,” Wang said.

Wang’s international team includes scientists from Australia, Spain, Germany, the United States, Canada, South Africa and France. In Eastern Australia ..
