LIGO is not the only gravitational wave observatory in the world. While LIGO's two detectors constitute a mini internal collaboration between LHO and LLO, an even larger gravitational wave observatory collaboration exists between LIGO and other detectors and researchers around the world, including Virgo in Italy and KAGRA in Japan. Data from LIGO, Virgo, and KAGRA are combined and analyzed jointly. This collaboration significantly enhances the search for gravitational waves.
