First candidates Discovered in the early 1970s with the development of X-ray astronomy. But we can say that the first candidates for the title of Black Hole Doubt Court were discovered with quasars in the early 1960s. In the following years from the end of the XXAnd Century, it is becoming more and more The stars were highlighted Between 5 and 15 solar masses, the largest black holes in the heart of large galaxies, It has a mass of one million to several billion solar masses.
This last hypothesis is not without problem, because everyone knows that in galaxies, the distance between stars can be assumed to form. This allows the scene to be revisited in another light, making it more enjoyable and believable.Without conflicts. In this case, an article was published today The Astrophysical Journal By a group And can read freely in it
For about a decade, there have been indications of the existence of intermediate black holes, and now promises to explain at least part of this existence, we see a cluster of atomic stars in a significant portion of large galaxies. That Atomic star clusters ( And this Stars when they have both old stars like the previous stars and young stars like the latter.), As we say in English, are at the center of most things And they are dense (by 106 At 10 p.m.8 Solar masses in the form of stars in about ten regions Radius) than
Stellar Encounter Catalysts
NSCs are found mainly in very large galaxies such as the Milky Way, and are usually found in very light supermassive black holes. Our galaxy has NSC and its Contains only about 4 million solar masses.
Observations made in the areaWith Spatial And visible through the telescope More than 100 galaxies with specific black holes in 29 samples were highlighted in the NSCs, which emerged from studies of data collected by both instruments collectively.
At an NSC, researchers estimate that a star hole born in the center would destroy and swallow up thousands of stars, thus becoming an intermediate-mass black hole toward the center of the galaxy. Calculations show that there is a density limit, which depends on the speed at which the stars in the clusters move, at which point the star-consuming growth process actually kicks into gear.
As predicted by the theory, NSCs above the calculated limit will grow more black holes that support the theory. The process of runaway growth can occur in any crowd dense enough, so even todayNot at the beginning of its history. This is another experimental prediction.
