Black holes are the perfect playground for physics, to search for new ultralight bosons. Bosons can form clouds around rotating black holes if their Compton wavelength is comparable to the black hole size, through a process called superradiance, extracting angular momentum and energy from the black hole and populating an exponentially large number of gravitationally-bound states. Gravitational-wave detectors and X-ray binaries measurements can be used to probe the existence of such boson clouds.
