Astronomers have spotted a runaway supermassive black hole, seemingly ejected from its home galaxy and racing through space with a chain of stars trailing in its wake.
According to the team’s research, which was published on the pre-print server arXiv.org
and has been accepted for publication in The Astrophysical Journal Letters, the discovery offers the first observational evidence that supermassive black holes can be ejected from their home galaxies to roam interstellar space.
The researchers discovered the runaway black hole as a bright streak of light while they were using the Hubble Space Telescope to observe the dwarf galaxy RCP 28, located about 7.5 billion light-years from Earth.
