Why are black holes just ‘wandering’ on the outskirts of their dwarf galaxies?

Astronomers have detected several supermassive black holes wandering through their dwarf host galaxies, providing new clues about how similar black holes evolved in the early universe.

Using the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) in New Mexico, the researchers identified 13 dwarf galaxies that are less than a billion light-years away from Earth and that host supermassive black holes. Astronomers estimate that these galaxies contain less than 1% of the mass of the Milky Way, making them the smallest galaxies known to host massive black holes, according to a statement.
