Curious, what are the mysteries about the blasting gas of the black hole?

Scientists observe the galaxy gases sprayed by large quality black holes in galaxies

Astronomers believe that the life of each galaxy will go through such a period: the galaxy will spray a large amount of gas inside, but they don't know what the "middle -aged crisis" of the galaxy is caused.

Once the gas spray occurs, the galaxy loses the raw materials needed to form a new star. The younger stars are younger in the galaxy. Researchers at the University of New York's Abu Dhabi want to know whether the super -quality black hole in the center of the galaxy is the culprit of this phenomenon, so they studied how the black hole activities helping galaxies discharge these gases.

"Our awareness of the correlation between the" super -quality black hole "and the entire galaxy gas jet is very poor. "Aisha AI Jezdi is a scientist who studies this field of New York University Abuzabe, and is also the first author of a paper. He has made such a statement in a report.

Researchers focus on Manga 1-166919 galaxy, and (Manga 1-166919) Here, on behalf of the galaxy, it was investigated a project called "APO drawing nearby galaxies". picture.

Astronomers discovered that Manga 1-166919 has the so-called active galaxy nucleus: because the energy of the disk of the ultra-quality black hole makes the center of the galaxy particularly bright, it is usually a pair of detective lamps. Shoot. This makes astronomers particularly interested in Manga 1-166919.

Observe the galaxy (galaxy) through the two means of radio waves and visible light. The researchers found that the two types of spraying materials of the super -quality black hole directly sent the gas out of the galaxy. Scientists have also found evidence for the formation of exorcotrane gases: to accelerate it in some areas, and then cool down in other areas.

Long-term research will not only tell us about the future of Manga 1-166919, but also let us know that the Galaxy and our neighbor fairy galaxies are experiencing the "middle-aged crisis", and they are gradually aging and turn red.

The study was described in a paper in the "Gorgeous Physics Magazine" published on August 4.

Black holes are extremely powerful gravitation in time and space, so that all particles and even electromagnetic radiation such as particles and light cannot escape. The general theory of relativity predicts that the tight quality can distort time and space to form a black hole; the boundary that cannot escape from the area is called an event vision. Although the event field has a huge impact on the fate and situation of the objects that cross it, the observations of the region seem to fail to detect any characteristics. In many aspects, the black hole is like an ideal black body, it does not reflect.

There are several ways to form a large quality black hole. The most obvious is formed by slow accumulation (starting from the size of the star). Another method involves a relativity star with Nebula with a stars with more than hundreds of thousands of solar quality. The star is unstable because its core generates positive and negative electrons to the radial disturbances caused by positive and negative electrons, and will shrink into black holes directly without forming a supernova. The third method involves a high -density star group that is tiring. Its negative thermal capacity will promote the decentralized speed of the core to become the speed of relativity. Finally, the native black hole was created from the external pressure at the moment of the Big Bang.

The problem of forming a large quality black hole is how to add enough material to a small size. To do this, almost all corner volume in the material must be removed. The process of moving the corner momentum outward is to limit the expansion of the black hole and cause the formation of the accumulation. According to observations, there are some gaps in the category of black holes. Some black holes that collapsed from the star have a maximum of 10 times the solar quality. The smallest large quality black hole has about hundreds of thousands of sun quality. But there is no black hole in the quality of the intermediary between them. However, a model refers to the unusually bright X -ray source. It may be a black hole in this missing range.
