Scientists believe a mysteriously bright object in a galaxy 90 million light-years away could be a rogue black hole evicted during the merger of two galaxies.
Astronomers have long hunted for galaxies that might be evicting supermassive black holes at their centers. Eviction would represent an important confirmation of Einstein’s theory of general relativity under extreme conditions and could help shed light on the influence such massive features have on the evolution of galaxies themselves.
Supermassive black holes tip the cosmic scales at millions to billions of times the mass of the sun. They are thought to lurk in the centers of most, if not all, galaxies. These behemoths are thought to play a key role in galaxy evolution by regulating a galaxy’s rate of star formation.
“Either way it’s something very interesting,” she says.
