Abstract
The detection of gravitational waves has revolutionized our view of the Universe and paved the way to a new era in multimessenger astrophysics. Since the first detection in 2015, the number of gravitational wave signals detected by LIGO-Virgo-KAGRA has strongly increased, reaching after three observing runs a total of 90 confirmed events, produced by the coalescence of compact binary systems of black holes and/or neutron stars. This results has been possible thanks to the international network of LIGO, Virgo and KAGRA (LVK) detectors, that has unprecedented sensitivity and localization capability, a key ingredient for multimessenger follow-up by ground-based and spaceborne telescopes. The talk will discuss the latest observational results of LVK and highlight prospects and challenges of gravitational wave and multimessenger astrophysics.
