Ultralight bosons can induce superradiant instabilities in spinning black holes, tapping their rotational energy to trigger the growth of a bosonic condensate. In this talk I will give an overview on superradiance and its applications focusing on the observational imprints of this process around spinning black holes which include: (i) the emission of monochromatic gravitational waves emitted by bosonic condensate formed through superradiant instabilities, potentially observable by current and future gravitational-wave detectors, and (ii) the formation of “gaps” in the spin versus mass plane of astrophysical black holes.
