In the early 1960s, the optical number of a source was successfully identifiedPowerful invention and baptism by radio telescopes at that time 3C 273, The Notice that she looks like one But it was his The light changed strongly to red. As a part of The relativist of an already well-developed period, which means it is in the billions Distance and so it gives, so much to see from a distance, scales Wonderful and almost unbelievable, because even a normal star or star eruption cannot be physically calculated by it.
Other researchers, while in the same decade Imposes itself soon after discovery In 1965, people like Igor Novikov were very bold and exploratory We proposed it, an idea we already call it May be parts Whose expansion at that time Delayed (assumption Backward center) They will say that these cosmic events are the reversal of the eruption of wormholes. They are absorbed in the form In another part of the universe, or even in another universe.
From quasars to ORCs
However, since 2019, British-Australian astronomer Ray Norris and his colleagues have been very confused by a few objects they have discovered.Australian square kilometer line Pathfinder (Askap), the Australian Radio Telescope Network, which served as a model for the much-anticipated. (SKA), a virtual giant radio telescope project, with a collecting surface area equal to one square kilometer, is operational and connects multiple instruments.
The first unusual object to be revealed by Ascob was named ORC 1, ORC ” Odd radio circles “, This can be translated as” Strange radio circles “.
As their name implies, they appeared in the form of rings on the radio, but had nothing to do with them in the visible domain, which dispelled the notion that they might be remnants.Or planetary nebulae may have this kind of feature as well. It can be ruled out that they are radio lobes associated with very large black hole jets because they are so irregular.
The distance of these circles and their size have not yet been determined at the outset. But it has changed and is a release Monthly Announcements of the Royal Astronomical Society (MNRAS), in which consultation is free , Begins to give some answers.
Astronomers mobilized Is the forerunner of the SKA we already pay for Take better care ORC 1. A new radio source was discovered in the center of the radio circle, which is associated with a galaxy. Finally, the data now collected suggest that we are in the presence of a ring a billion light years away. Correspondingly one million light years in diameter.
The bubbles appear centeredDetected, so it is clear that they were thrown by these galaxies, which looked like the front of a hemispherical eruption shock wave.
The artist’s idea of the formation of one of the strangest radio circles since the eruption of the Central Galaxy. It is believed that the bubble from the eruption took 1 billion years to grow as we know it today. Radio circles are very large (millions of light years in diameter) that extend beyond their original galaxies. © Sam Moorfield / CSIRO
The nature of the explosion, however, remains elusive. This may be an unpredictable and unpredictable event when two very large black holes collide after the merger of two galaxies.
It may also have formed suddenlyThe gravitational pull of about one million stars in a galaxy causes a sudden eruption of plasma with the birth of these stars leaving the galaxy.
Once SKA is fully operational, we need to know more about gaining additional advantage in clarity.
