Straight to the source: the LIGO-Virgo global network of interferometers opens a new era for gravitational wave science

Localisation OG sources

The Virgo collaboration and the LIGO Scientific Collaboration report the three-detector observation of gravitational waves. This result highlights the scientific potential of a global network of gravitational wave detectors, by delivering a better localization of the source and access to polarizations of gravitational waves.
The two Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA and the Virgo detector, located at the European Gravitational Observatory (EGO) in Cascina, near Pisa, Italy, detected a transient gravitational-wave signal produced by the coalescence of two stellar mass black holes.

In yellow : localisation from the 2 LIGO detectors.

In green : localisation using datas from 3 detectors (LIGO et Virgo).

In purple : more precise localisation after detailed data analysis.
