For the first time, an astronomical team was able to observe the final stages of the fusion between several pair of galaxies.
This is a theory event. but it has not been verified so far.
Led by Michael Koss, a research expert at Eureka Scientific Inc., the team examined hundreds of close galaxies using images from the WM Keck Observatory in Hawaii and the Hubble Space Telescope of NASA.
The research team captured pairs of super-mass black holes, each of which occupied the center of their own galaxies. approaching each other before joining one Unique and giant black hole, NASA announced a statement.
One of the most violent events
Most (if not all) galaxies are in the center super mass black holes More than billions of masses from the Sun or the Earth.
The black hole in the middle of the galaxy is called the Milky Way. Sagittarius A * (Sgr A *) and has a floor weight of 4.3 million.
The mergers of the galaxies were more frequent in the first phase of the universe. Therefore, these images provide a rare perspective. One of the most violent events in the universe.
They are also what will probably be The Milky Way, coupled with the neighboring galaxy Andromeda.
Both galaxies contain black holes in super mass in their centers. They will collapse into a larger black hole and unite.
The fusion of galaxies is a slow process. more than one billion years.
Under the force of infinite traction, the two galaxies slowly approach one another until they finally unite.
Eureka Scientific Inc. team confirmed it. black holes in galaxies grow faster When they approach the collision.
, The fact that black holes grow faster and faster as the fusion process progresses means that these encounters between galaxies are really important when it comes to understanding us. how these objects they came be very monstrous"In the NASA statement said his colleague Laura Blecha of the University of Florida.
The team focused on galaxies, an average of 330 million light-years from the Earth, The cosmic sense is relatively close.
Most of these galaxies resemble the Milky Way and the galaxies of Andromeda. The team analyzed 96 galaxies in total, with a total of 385 galaxies in the Keck telescope and the Hubble archive.
The Milky Way is now approaching the Andromeda galaxy an average of 300 kilometers per second So at one point they will unite a single large galaxy.
But now you don't have to worry about it: Experts agree that several billion of the year
