What is the fusion of many galaxies with black holes for the future of the Milky Way?



A team of astronomers has been able to observe for the first time the final stages of fusion between many galaxy pairs.

This is a fact that was considered but was not immediately verified.

The team headed by Michael Koss, a researcher at Eureka Scientific Inc., examined hundreds of nearby galaxies using images from the WM Keck Observatory in Hawaii and NASA's Hubble Space Telescope.

The research team occupied pairs of oversized black holes, each of which captured the center of their respective galaxies, approaching each other before joining a unique and gigantic black hole, NASA said in a statement.

One of the most violent events

The center of most (if not all) galaxies are located oversized black holes with a mass billions more than that of the sun or the Earth.

The oversized black hole at the center of our galaxy, the Milky Way, is called Sagittarius A * (Sgr A *) and weighs 4.3 million feet.

Mergers of galaxies were more common in the early stages of the universe. Therefore, these images provide a rare picture one of the most violent events in the universe.

Default also what will happen probably when the Milky Way interconnects with the neighboring Andromeda galaxy.

Both galaxies contain oversized black holes in their center, which eventually will crash and unite in a larger black hole.

Galactic Fusion

A fusion of galaxies is a slow process that lasts more than a billion years.

Below the relentless force of gravity, two galaxies are slowly approaching each other until they eventually join.

In their analysis, the team of Eureka Scientific Inc. confirmed this black holes of galaxies grow faster when approaching the conflict.

"The fact that black holes grow faster and faster as the process of fusion evolves tells us that these encounters between galaxies are really important when it comes to understanding How; these objects they arrived to be so monstrous"said Laura Blecha, a partner of the University of Florida, in the NASA statement.

The team focused on galaxies that are on average 330 million light-years from Earth, relatively narrowly at a secular level.

Many of these galaxies are similar to the galaxies of the Galaxy and Andromeda. In total, the team analyzed 96 galaxies observed with the Keck telescope and 385 galaxies from the Hubble record.

The Galaxy is now approaching the Andromeda galaxy at an average speed of 300 kilometers per second, so at some point they will unite in a single large galaxy.

But you do not have to worry now: the experts predict that the merger will only take place through means several billions years.
