Descripción
The direct detection of gravitational waves has opened a new observational window onto the Universe, transforming both fundamental physics and astrophysics. A global network of ground-based interferometers — including the Advanced LIGO, Advanced Virgo, and KAGRA detectors — is now operating at unprecedented sensitivities, routinely detecting signals from compact binary coalescences. I will review the current status of these observatories, highlighting the most recent observing run (O4), its achievements, and the challenges encountered. The talk will also outline the technological upgrades planned for the upcoming observing runs and the path toward next-generation detectors such as the Einstein Telescope and Cosmic Explorer.
At lower frequencies, space-based detectors like LISA will open a complementary window, targeting sources from massive black hole mergers to stochastic backgrounds, and bridging gravitational-wave astronomy with cosmology and particle physics. I will discuss the experimental landscape across these frequency bands, emphasizing synergies among current and future facilities and their role in enabling multi-messenger and fundamental physics discoveries in the coming decade.
