Milky Way's supermassive black hole may have 'unseen' siblings

Post by Dragon on Wed Apr 25, 2018 10:49 pm

Astronomers are beginning to understand what happens when black holes get the urge to roam the Milky Way.

Typically, a supermassive black hole (SMBH) exists at the core of a massive galaxy. But sometimes SMBHs may "wander" throughout their host galaxy, remaining far from the center in regions such as the stellar halo, a nearly spherical area of stars and gas that surrounds the main section of the galaxy.

Astronomers theorize that this phenomenon often occurs as a result of mergers between galaxies in an expanding universe. A smaller galaxy will join with a larger, main galaxy, depositing its own, central SMBH onto a wide orbit within the new host.

In a new study, researchers predict that galaxies with a mass similar to the Milky Way should host several supermassive black holes.

A black hole, a million times more massive than the Sun, fired off a high energy x-ray burst detected by NASA's NuStar mission on its first observing campaign.

Unidentified matter superheated to around 100,000,000° celsius emitted these hard x-rays.
