Abstract: The existence of ultralight bosonic particles is well-motivated by physics beyond the standard model, and could comprise dark matter. If these particles exist, they could interact directly with gravitational-wave interferometers, causing small, time-dependent oscillations of their components, and therefore a detectable differential strain. The signature of these particles resembles that of continuous gravitational waves, because both are expected to be monochromatic with small changes in their frequencies. Already results from continuous wave searches have been mapped to constraints on the boson mass, assuming that axion clouds form around rotating black holes and deplete over time.
