'Shocking' about the Milky Way and black holes 'wandering'

In the new study, the team of astronomers from the Yale Astrophysics Center, the University of Washington, the Institut d'Astrophysique de Paris, and University College London predicted that the Milky Way galaxy is abundant.

Typically, a supermassive black hole will exist at the core of a giant galaxy.

But sometimes they can "wander" in the host galaxy, around the center in areas like spherical star regions around the main part of the galaxy.

Astronomers hypothesize that this phenomenon often occurs due to the merger between the Milky Way and other galaxies.

The co-authors predict that the Milky Way galaxy stores some supermassive black holes.

The small galaxy will join a larger main galaxy, causing black holes to play in a new orbit. In the new study, Dr. Michael Tremmel and co-authors predict that the storage of some holes Super big black.

The researchers used a new advanced cosmic simulation, Romulus, to predict the movement dynamics of supermassive black holes in galaxies with greater precision than previous simulation programs.

"We are not sure that any supermassive black hole can wander and will come close to our Sun leaving any impact on our Solar System in the future , " said Dr. Tremmel said.

"We estimate that black holes wandering the Milky Way are likely to affect the Solar System every 100 billion years or longer, or nearly 10 times the age of the universe."

"Because super-large black holes wandering are predicted to exist far from galaxy centers and outside galaxies, they cannot secrete more gas - making them very mysteriously invisible , " he said. more.
