Unusual collision of three supermassive black holes and its consequences

Some of the most mysterious objects in the universe.- black holes hide an incredible amount of secrets. Scientists all over the world are puzzling over such questions as why supermassive black holes exist in the center of galaxies, which is beyond the horizon of events, and also whether black holes can be a portal to other universes. However, today scientists know more about these space objects than ever in history. We recently wrote that NASA introduced the world to visualize a black hole. Today we will tell you about a new study of astronomers. Scientists have discovered something surprising - just three black holes can collide with each other.

This is how the collision path of three galaxies looks like

Why is this discovery an anomaly?

In the vast endless, expanding universegravity is in charge of everything. Countless different celestial objects collide with each other, be they galaxies, stars or planets. Recently, scientists have discovered three supermassive black holes that are located in the centers of three galaxies. What makes this phenomenon unusual is that at once three galaxies, which are located a billion light-years from our planet, collide with each other. However, there is another oddity - it turned out that these supermassive objects glow in X-rays.

In 2017, scientists announced to the world about the discovery ofgravitational waves predicted by Albert Einstein's theory of relativity. Gravitational waves reached our planet, arising from the collision of two supermassive black holes. Thus, researchers for the first time received data on the merger of these space monsters. However, according to scientists, LIGO or the VIRGO Observatory will not be able to detect gravitational waves that arise as a result of a collision of three galaxies, due to their low frequency. But first things first.

How did scientists discover the anomaly?

It all started with the discovery of a galaxy merger inoptical light telescope Sloan Digital Sky Survey (SDSS) in New Mexico. The researchers then examined the data collected by the NASA Wide-field Infrared Survey Explorer (WISE) spacecraft. Scientists claim that WISE detected infrared radiation during the merger of galaxies. Further observations in x-ray and optical light confirmed astronomers' assumptions that a black hole is in the center of each of the three galaxies.

Subsequently, NASA X-ray ObservatoryChandra discovered X-ray sources near each of the centers of merging galaxies. This suggests that near the center of the galaxies a lot of gas and dust is consumed, and this is a sign of the presence of a black hole. According to experts, each telescope provided unique data, thanks to which experts confirmed that there is a truly unusual discovery in front of them - just three black holes are in the center of the colliding galaxies.

According to researchers, discoveredthe collision of such massive objects is different from the collision of two black holes. The fact is that each of the three black holes is the core of the galaxy, which actively absorbs material. It is because of the fact that the material emits bright light during the absorption process, scientists were able to detect this unusual system. Experts note that it is rather difficult to detect such objects since they are surrounded by a large amount of dust and gas, and this greatly complicates the search.

Black holes help galaxies evolve

It's no secret that all space objectsThere is a life cycle. So, astronomers claim that the anomalous system discovered during the last study indicates the evolution of galaxies. The key to understanding such processes is a black hole. Computer simulation showed that about 16% of galaxies that collide with each other and in the center of which supermassive black holes rotate will interact with a third supermassive black hole. According to researchers, the third black hole contributes to a faster process of merging galaxies.

This study may also shed light on“The secret of the last parsek” - it tells that during the merger of two galaxies, black holes in their centers do not collide with each other, but fly around the obstacle, thus forming a dual system at a distance of several parsecs. Thus, the third black hole can finally unite them.
