About 7,800 light-years away – within our galactic neighborhood – the NGC 6397 sphere is essentially a number of stars held together by gravity. Previously it was thought that there was a black hole of medium size in the middle. But after further investigation, a team from the Paris Institute of Astrophysics has confirmed that the browser hosts a pod of smaller black holes, holding things together in a more distributed system.
Previous research had suggested that the heart of the universe could accumulate such star-shaped black holes, but this paper goes a step further by measuring the size and magnitude of these objects. The team was researching published this week in the journal Astronomy and Astrophysics.
To identify the mystery at the center of the cluster, the researchers looked at how stars near their center moved using data from two space telescopes, the Hubble Space Telescope and the Gaia Space Agency’s Gaia observatory. Europe.
“We found very strong evidence for an invisible mass in the dense heart of the universe, but we were surprised to discover that this extra mass does not look like a point,” said Eduardo Vitral of the Paris Institute of Astrophysics. in its NASA Press Release. If only one black hole was to blame, the amount of mystery would be more dense. “We are the first survey to provide both the mass and size of what appears to be a collection of mostly black holes in the middle of a collapsed global browser. ”
Intermediate black holes have long been thought of as a missing link in black hole evolution. Perhaps smaller in the public eye than supermassive black holes (which have proof of existence) or teenage primordial black holes (which are still theoretical), would be intermediate black holes, as the name implies. their suggestion, helping astronauts to understand how these enigmatic structures develop.
“Our analysis showed that the orbits of the stars are almost random across the globe, rather than being systematic or very long,” Gary Mamon, also at the Paris Institute of Astrophysics, explained in the same news. If the orbits of the stars were coordinated, it would suggest a single control. Instead, the stars seemed to be invested in their own ad-hoc moves. Mamon and Vitral believe this is because thick stellar remains such as white dwarfs, neutron stars, and black holes – formed when stars reach the end of their life and fall into themselves – have gone below to the center of the cluster, in a three-sided Plinko type. Stars of lower mass, on the other hand, made their way to the edge of the brace.

“The authors have carried out an in-depth study, and the results of this work show an unexpected improvement in the hunt. [intermediate black holes] in global collections, ”Misty Bentz, a recent Georgia State University psychologist not affiliated with the paper, said in an email. “However, there are many assumptions that are necessary when conducting studies like this, and the results still leave room for potential. [intermediate black hole] in this world clock.
Artistic images of the global body, seen in the video above, look like someone pushing space-time with a cannonball on a stellar scale. A chase of mass-force force binds out of the cluster; the remnants of dead stars keep their brothers alive together in a gravitational realm (or bring them in, according to your view). Not surprisingly, there would be so many white spots, neutron stars, and black holes in this area; NGC 6397 is a group of old organizations, clicking in at 12.6 billion years old, give or take half a billion, giving stars enough time to complete their life cycles.
Bentz said that the new study does not fully show that there are many small black holes in the helmet instead of one larger one, “but if that is the case, it indicates that the origin of the holes horrible black even more mysterious than they already are! “That’s because, she explained,“ we think black holes need to have grown from smaller seeds. But the results of this study show that it is really difficult to put together many small black holes in a sphere, because the spherical collection is old and yet the small black holes are still hanging around them. themselves, not united to each other. ”
This is an interesting find. Although there were supposed to be black holes back in 1916 by Albert Einstein, it was only two years ago, in April 2019, that scientists captured true image of one. Clearly, we have a lot more to learn about these mysteries.
