Description
Continuous gravitational waves (CW) are long-lasting signals predicted from spinning neutron stars and other exotic sources, representing a major target of current gravitational wave searches. In this talk I will review the most recent observational results from CW searches, covering from the targeted searches for known pulsars to the all-sky surveys for unknown sources, with a particular focus on results obtained during the latest LIGO–Virgo–KAGRA observing runs. I will discuss the astrophysical implications of the upper limits achieved on gravitational wave emission and the constraints they place on neutron star deformation and equation of state. I will also briefly address results from searches for a stochastic gravitational wave background, highlighting the complementarity with transient search efforts.
