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 (BHs) through superradiant instabilities, forming macroscopic bosonic condensates around astrophysical BHs. The formation of such condensates can lead to several striking signatures, such as the emission of continuous gravitational-wave (GW) signals, lack of highly spinning BH in particular BH mass ranges, modifications to the dynamics of binary BH systems, among others. In this talk I will give an overview of this research program, focusing on the work I have been involved in over the past few years and on recent developments.
