"The spin of stellar mass black holes is a particularly significant property, as black holes have rapid rotations that generate a region of space called the ergosphere around the event horizon, where the torque on spacetime is so great that an object would have to travel at a velocity exceeding the speed of light just to stay in a stationary orbit. Analysis of this region has resulted in some interesting physics predictions, one being the phenomenon of superradiance. When a wave (whether of electromagnetic radiation or matter) enters the ergosphere with a specific trajectory, it can exit the black hole environment with a larger amplitude than the one with which it came in— this amplification process is called black hole superradiance. It was an effect first described by Roger Penrose nearly 50 years ago and describes how work can be extracted from the ergosphere of a black hole.

Now, a study led by Daniel Baumann of the Gravitation Astroparticle Physics Amsterdam (GRAPPA) at the university of Amsterdam and in collaboration with John Stout of Harvard University describe how superradiance may create boson orbital clouds around black holes, similar to electron orbitals around the hydrogen nucleus, forming a gravitational atom. The orbital condensates around the black hole nucleus can even be ionized, similar to the photoelectric effect in atomic physics, leading to binding of black hole binary systems.
The research team proposed that the ionization effect can be observed by analyzing specific signatures within gravitational waves (in gravitational wave astronomy) emitted by inspiralling binaries.
