Explore methods and results of searches for continuous gravitational waves in this lecture from the ICTS Summer School on Gravitational-Wave Astronomy. Delve into advanced techniques for detecting long-duration gravitational wave signals from sources like rapidly spinning neutron stars and exotic phenomena such as axion clouds around black holes. Learn about the latest search strategies, data analysis methods, and recent findings from ongoing efforts to detect these elusive signals using LIGO, Virgo, and KAGRA observatories. Gain insights into the challenges and opportunities in this cutting-edge field of gravitational wave astronomy as presented by expert researcher Alicia Sintes from the University of the Balearic Islands.
