Abstract: Ultralight bosonic fields are compelling dark-matter candidates and arise in a variety of beyond-Standard-Model scenarios. These fields can tap energy and angular momentum from spinning black holes through superradiant instabilities, during which a macroscopic bosonic condensate develops around the black hole. Striking signatures of this phenomenon that have been studied over the past few years include for example gaps in the spin-mass distribution of astrophysical black holes and continuous gravitational-wave signals, that could be detected either as individual sources or as a stochastic gravitational-wave background. In this talk I will give an overview of the status of this research program and discuss some of the latest searches for signatures of ultralight bosons in gravitational-wave data.
