A strange signal in the background created by a connection of two black holes could be the first system of three -star mass black holes captured in gravitational waltures.
According to the new analysis of Ligo-Virgo-Kagra collaboration data, 2019 Binary data data Black hole The collision showed signs of anomal acceleration that shows that there is one third Black hole;
“This is the first international evidence of a third compact object in the binary Black hole The merger event, ”says Wen-Biao Han of the Chinese Academy of Sciences.
“This reveals that the binary black holes GW190814 may not have been formed separately, but there were more complex parts of the gravitational system, providing significant insights on binary black hole formation paths.”

From the very first detection of gravitational waves back in 2015, scientists cataloged about 300 merger-events, where binary black holes have finally completed their orbit and collide, blend into one object and send gravitational waves rotating through space tissue.
Astronomers can analyze those vibration signals to determine the masses of related black holes, some connections mention what we call hierarchical mergers – a series of merger joints leading to larger and larger black holes.

This is because the star mass black holes forms the upper boundary of the mass, where the massive star goes supernova and throws the outer layers, leaving a core that collapses under its severity to become a Black hole;
Above a certain star mass the whole set and Kaboodle just explode completely, core and all, without leaving anything other than garbage – so if a Black hole is detected above this limit, scientists conclude that the aforementioned Black hole is a product of the previous merger.
GW190814 was not related to a Black hole above the mass boundary. On the contrary, one of the black holes is believed to be the smallest of the kind that has ever been discovered, so a small iTOS on the neutron star threshold – only 2.6 times more than our own solar mass.
Another Black hole A significantly larger, about 23 solar masses participated. This mass ratio is for what is predicted for star evolution models – binary objects are usually expected to consist of two similar sizes.
A team led by Shu-Cheng Yang from the Chinese Academy of Sciences believes that this mass relationship indicates a complex past; A couple of black holes that were drawn together by a third, much larger object gravitational pull, around which binary orbit.
So they looked more closely at gravitational wave data. A couple of black holes flying a larger -third Black hole; Researchers found out how it would occur, then compared their model to GW190814.
According to their model, the data show that the acceleration of the gaze line is 0.0015 times higher than the speed of light in a vacuum with a level of confidence about 90 percent-about a third, unseen, unseen, unseen, unseen Black hole;

This result can mean that Black hole At least in certain circumstances, the merger may occur in much more difficult circumstances than we knew. There may be even more clues about these – other – complex circumstances hiding in data, waiting for someone to create tools that will see them.
In addition, conclusions provide more evidence of hierarchical merger by confirming existence Black hole Trinaries where merger can take place.
Expected Black hole merger. Perhaps it will also show a bit of the environment in which they take place and in different ways Black hole Interaction can be conducted throughout the universe.
