Gravitational Waves: the Theorist’s Swiss knife

Gravitational wave (GW) astronomy has revolutionised our understanding of the Universe by providing a novel observational window into the most energetic and dynamic phenomena in the cosmos. The numerous direct GW detections by the LIGO-Virgo-KAGRA collaboration have significantly enhanced our understanding of compact objects, provided tests of general relativity in the strong-field regime as well as tests of high energy physics beyond the Standard Model at energy scales inaccessible at colliders.
After a short introduction, I will first review how GWs are used to constrain particle physics beyond the Standard Model, early Universe cosmological scenarios, dark matter candidates, or even quantum gravity proposals. I will then discuss the angular power spectrum of gravitational-wave transient sources as a probe of the large-scale-structure of the Universe.
