Abstract: 
In recent years, direct observations of transient gravitational waves from catastrophic collisions of black holes and neutron stars have opened a new window to the extreme universe. Meantime, the hunt for other sources and types of gravitational waves, like the much fainter continuous gravitational radiation emitted by non-axisymmetric spinning neutron stars has also been going on. 
This talk will review the observational results obtained by the LIGO, Virgo and KAGRA collaborations in the first six years of gravitational wave detections, and will also present different  searches for continuous  gravitational waves. These searches are extremely challenging, and can be very computationally expensive when the source parameters are not known or not well constrained.
