Quasi-monochromatic, quasi-infinite duration gravitational-wave signals, i.e. continuous gravitational waves, represent one of the many types of signals that have yet to be detected by LIGO, Virgo and KAGRA. Though they are modelled rather simply compared to signals from binary black hole and neutron star mergers, the inherent weakness of continuous waves, as well as the large parameter space over which we must search, have made detecting these signals a major challenge. In this talk, I will describe the possible sources of continuous gravitational waves, e.g. isolated neutron stars, depleting boson clouds around black holes, and primordial black hole inspirals, and the data analysis principles and techniques used to search for these sources. I will also present recent constraints from continuous gravitational-wave searches, and comment on the prospects of detecting these signals in future observing runs and with future detectors.
