Astronomers have seen the final phase of the galaxy fusing for the first time – Science Scan – cnBeta.COM


According to foreign media, astronomers saw the final phase of the merger of the galaxy. Through thick and dusty gas, the pairs of super-massive black holes approach and approach and grow rapidly.of

Most often, if not all, galaxies, there are black holes in supermarkets, millions of millions of miles from the sun. For example, Sagittarius A *, in the middle of the Milky Way, is a bright and compact radio wave source, the closest black hole supermarket, with a sized 4.5 million-sq.

In the Galaxy NGC 6240, two smaller galaxies are visible in the final stages of fusion. The black axes of two small galaxies grow rapidly, consuming gas and dust that combine the galaxy.

Some galactic nuclei are in the last phase of fusion. On the upper side is the NGC 6240 galaxy. The left image is taken up by a 3-sided space camera by the Hubble Space Telescope. The image on the right shows the galactic nucleus shot by the Keck Observatory with infrared rays. The four images in the lower four galaxies are translated through the Pan-Star program. "Panoramic Sky Telescope and Quick Response System" and Keck Observatory.

Previous studies have found that the galaxy reconciliation can lead to growth of supermassive black holes. Researchers suggest that black holes join together larger black holes in the middle of the galaxy's blast.

The unification of the galaxy with the black holes in the supermarket gives a great deal of opportunity to dissolve stars and give them substance. This filtering has a large amount of radiation and maybe it's a driver behind the quasar. Quasar is one of the brightest objects in the universe. However, according to the authors of this new paper, it is complex that a prototype that protects supermassive black holes against galaxies. Although some studies show the connection between the Quasars and the combined galaxies, other studies have not found this association.

The apparent lack of correlations is a possible explanation that gases and powders around the galaxy can severely darken black holes between the combined galaxies. In the initial phases of the merger, that is, when the galaxies have more than 16,000 light years. The authors of the study have indicated that computer simulations show that the last phase of the galactic limit must occur, that is, the distance between the galactic nuclei is less than 10,000 light-emitting diodes.

Nowadays, researchers have seen a couple of galaxies in subsequent phases, and black holes supermarkets are constantly approaching their center. These finds will give you clues as to how big black holes grow larger.

Researchers reported 10-year X-ray data from the NASA Neil Gehrels Swift Observatory for 10-year-old data to see hidden black holes. When black holes feed on substances, energy X-rays of these "active" black holes can be seen, even when they are blocking thick gases and dust.

Next, the researchers analyzed galaxies that collect X-ray information from the Hubble Space Telescope and Keck Observatory data (Hawaii, USA). Michael Koss, first author of the paper, said that the Keck Observatory could have a star-shaped computer-controlled deformed mirror through a technique called optic-adaptive. "The resolution's growth is great."

Coase Eureka is an astrophysicist of scientific technologies in Oakland, California. He said: "This is the equivalent of visual 20/2000 (visual acute 0.1), that is, wisely in the legal sense 20/20 perspective (visual power 1.0), so we can see people. The galaxy is a huge galaxy."

In all, the researchers analyzed 96 galaxies from 385 galaxies seen by the Keck Observatory and the Hubble telescope. The average distance between the galaxy and Earth is 330 million light years, close to the cosmic scale, and many galaxies are similar to Milky Way.

The researchers found that more than 17% of the galaxy had a couple of black holes that indicate that they are at the end of the galaxy melting. These findings are consistent with researchers' computer simulations, which means that active black holes hidden in gas gases and dust galaxies comprise many super-black holes.

"The galaxy's unification can be an important way to grow black holes," Coase said. Milky Way is currently undergoing a process linking the current Andromeda Galaxy, and two super-black metal galaxy holes will eventually knock and match. Now, there are millions of moon-lattens between the two galaxies, but continuously (the Androids Way) we are moving 400,000 kilometers per hour on the Andromeda galaxy, "Coas said. 6 million years ago, the Milky Way or Fairy Galaxy will not exist, leaving only one larger galaxy. "

For galaxies hidden from gas and dust, NASA's James Webb Space Telescope may be more clear. Infrared space telescope is launched in 2021. Next-generation astronomical telescopes, such as the Thirty Meter Telescope, the European Telescope European Telescope (E-ELT) and the Magellan Large Telescope, will also be used by active telescope astronomers. Bring a more accurate galaxy image. Researchers have also said that James Webb's space telescope could also measure the quality, growth rate and other physical characteristics that are closer to the nearest black holes.

The results of the study were published on November 7 in the field of Nature.
