First Interim: Fill in The Hole

Super massive black holes, and miniature quite often are found by scientists in studies of the universe. However, in this chain the size of a large gap yawns: definitely proven and reliable observations of black holes of intermediate mass (of the order of hundreds or thousands of solar masses) are still there. Although some reports have already been made of their discovery ("Hole-teen"), in fact, they are not so straightforward. Some experts even inclined to believe that these holes can not exist in principle ("intermediate complexity").

Super massive black holes, and miniature quite often are found by scientists in studies of the universe. However, in this chain the size of a large gap yawns: definitely proven and reliable observations of black holes of intermediate mass (of the order of hundreds or thousands of solar masses) are still there. Although some reports have already been made of their discovery (”Hole-teen”), in fact, they are not so straightforward. Some experts even inclined to believe that these holes can not exist in principle (”intermediate complexity”).

But now, I think in this discussion, you can put the point: a group of astronomers reported the first observations of established facts in a remote galaxy, the black hole mass of more than 500 solar.

In principle, black holes can have masses in a very large range, from the Plank (which are so small that they can not see them yet) to super-massive, millions and even billions of suns. The relatively small black holes of stellar masses come from the remains of massive stars after their death as a result of huge explosions. But that’s just the size of holes between super massive and stellar so far not been observed.

Recently observed an object called HLX-1 became the first mass which refers to this gap. A team of astronomers led by Sean Farrell (Sean Farrell) found him at the border away from us by about 290 million light-years across the galaxy. According to their estimates, the hole emits X-rays in approximately ten times more intense than the black hole of stellar mass, implying that it is much harder. On the basis of this radiation, scientists found it a lot – about 500 solar.

However, the finding leaves open the crucial question of where is it that these black holes come from? It is possible that they are the product of hostile mergers and acquisitions between black holes have appeared in a dense star cluster near each other. According to another version, such objects are generated by the death of the oldest first-generation stars, which are believed to have been much larger than the present.

Incidentally, the observation of HLX-1 tips the scales in the direction of this second hypothesis, because the hole is not just on the outskirts, and even beyond the galaxy, where there is not dense stellar clusters.
