Supermassive Black Holes: Study some "wandering" through galaxies



B Missing holes are the focus of human life very quickly; They make it easy to think about your tiny existence in the expanse of space. But it sometimes seems, black holes alone have to think and wander, says an astronomer at Yale University Inverse .

In a new study published Tuesday in The Astrophysical Journal Letters researchers describe the strange habits of "wandering supermassive black holes". Black hole stans know that supermassive black holes exist in the center of galaxies, right? Well, sometimes it turns out that supermassive black holes "wander" through their galaxy and solemnly listen to Elliott Smith's either / or something dark and thoughtful. (Not that I judge it's a good album, I'm just saying that a human can only handle so many raw emotions at once.) Maybe black holes have another depth ability.)

"A wandering supermassive black hole is a black hole of at least 1

million solar masses that exists outside the center of its host galaxy, "says study lead author Michael Tremmel, an astronomer at Yale, Inverse . "In the specific case of our simulations, we define such wanderers as at least 2000 light years from the center of the galaxy, and in most cases our simulations predict that these black holes are actually even further away."

In fact, Tremmel and his team arrived According to computer simulations, galaxies that are similar in mass are likely to host many supermassive black holes, some of them may like to roam around. The researchers used a cosmological simulation program called Romulus.

It's still not clear what causes WSMBH, but Tremmel says he and his team have a solid idea.

"You can think of these black holes as" failed "fusions between two supermassive black holes," he explains. "In some cases, their respective supermassive black holes will fuse together after the fusion of galaxies and unite. In these "wanderers," the smaller galaxy was destroyed by the larger galaxy so that it removes its supermassive black hole far from the center of the larger galaxy where it can not efficiently sink in and mingle with the galaxy's central, supermassive black hole. "

Tremmel hopes his team's research can serve as a springboard for other models predicting supermassive black hole fusion rates investigate how we can actually "find" some of them hiding in the Milky Way.

"I think the most direct line of future research on migratory black holes is to see how we are capable of their presence in our galaxy or other nearby massive galaxies (such as Andromeda, for example), "he says," they do not accumulate gas, so they do not glow as bright as many of the black holes we can see. "We're likely to notice their gravitational influence surrounding gas and stars, but since the density of stars and gas is sparsely located far from the center of a galaxy, it will be difficult be. "

But still, from" failed mergers "? That's a pretty rough start. No wonder why they are condemned to wander the galaxy.
