Description
Gravitational waves, predicted over a century ago by Einstein’s theory of General Relativity, have become a powerful observational tool for probing the Universe. I will briefly introduce the physical nature of gravitational waves and the interferometric methods used to detect them. I shall present the scientific results from the recently completed fourth observation run of the LIGO, Virgo, and KAGRA detectors, highlighting key astrophysical discoveries and their implications for gravitational-wave astronomy. I will conclude by outlining the contributions of the Polgraw group within the Virgo Collaboration, emphasizing our role in data analysis and detector development.
