Odd radio circles in space may come from black holes at their centers

The strange formation of radio circles may be caused by the collision of two large black holes in the center of the elliptical galaxy closed in the ORC1C. These strange radio circles, or ORCs, aptly named, are not invisible radio waves that emit any rays from different waves, unlike many other objects seen on radio waves. This new practice has long been known as Odd Radio Circles or ORC, in line with the creative nature of the naming conventions of astronomers. ORCs are so named because they are large, round objects that shine brightly on the edges of a radio band, but they cannot be seen by bright televisions, infrared, or X-rays, and at this stage, astronomers do not know what they are. there is. here it is. . . .

An international team of astronomers has discovered a unique radio circle using the world's most powerful radio telescope. To help scientists understand the cosmic mysteries of the cosmic secrets, the satellite image of the South African Radio Astronomy Observatory (SARAO) MeerKAT captured the sharpest image of the ORC, prompting scientists to reveal more details about the ORC in a new study released today. Royal Astronomical Society. Like a faint blue and bluefish floating in the vast ocean of space, this image is a complete but real cosmic phenomenon known as the odd-numbered radio circle (ORC). New observations suggest that the strange radio circuit is made up of fast electron beams and has a complex internal structure made up of many arcs.

We now have beautiful pictures of one of these rings taken by the South African telescope MeerKAT, which shows the ORC in amazing detail. For example, MeerKAT detects a small radio drop in one of these rings, which is located in a distant galaxy. Demonstrating the dark clouds of the South African MeerKAT telescope on the rings indicates that the rings are on the edge of the round shell around the galaxy, similar to the shock of a large explosion in the central part of the galaxy. The circles are probably the largest eruption of hot gas about a million light-years from the center of the galaxy.

The mysterious radio spectrum is nearly one million light-years across, larger than the galaxies orbiting it. It will not happen, because the ORCs are round, unlike the complex clouds we see in radio galaxies. We now see that each ORC is focused on a galaxy that could appear at any time shortly. In five of these, astronomers saw galaxies among three of them, suggesting that rings could form a certain type of galaxy.

The new MeerKAT features show that five of them have galaxies with large black holes in them. Astronomers believe that the largest black holes are found in almost every major galaxy, including the sun. Astronomers can detect large black holes by observing their effects on stars near gas.

Scientists cannot detect black holes directly with X-ray telescopes, light, or other types of magnetic fields. The latest data from Chandra, XMM-Newton, and NASA's Hubble Space Telescope supports the idea of ​​medium-sized black holes. Both the combination of black holes and starbursts is rare, which explains why ORCs are so rare (only five have been reported so far).

Chandra and NASA's Hubble Space Telescope then collected data for "continuous explosion" events, and together these observations led astronomers to conclude that gamma may occur when a black hole and a neutron star collide to form another ray of a light. . black hole. Such explosions may be related to the rapid radio explosion or the collision of black holes with neutron stars that produce gravitational waves. First, the collision of two large black holes in the center of the Milky Way may cause a massive explosion; The vast amount of energy reflected on the radio, nearly a million light-years across, is said to be the remains of this explosion because it extends beyond the galaxy itself.

Further analysis of the most sensitive radio telescope will be required to determine which of the three main options is correct. Professor Elaine Sadler, the Senior Scientist at the Australian Telescope CSIRO, which includes the ASKAP radio telescope, said ASKAP and MeerKAT are now working together to quickly and effectively detect and explain strange radio circles. Drs. Jordan Collier of the Data-Intensive Intercollegiate Institute for Astronomy, who compiled a new data-based image from SARAO television station MeerKAT, said continuing to look at unusual radio circles would give researchers more clues.

One of the authors of the paper, Professor Ray Norris of Western Sydney University and the Australian national scientific center CSIRO, said only five radio stations had been discovered in space. Astronomers detect when a star is close enough that some of its orbits will be absorbed by the gravitational pull of the black hole, producing X-rays in the process. Black holes have one side called the event horizon, where things can collapse and nothing can come out. The dense cluster then descends to the center of the galaxy, were black holes in the center combine to form a much larger black hole.
