Gravitational waves and black holes coalescence

Press Release of 11 February 2016

In February 2016 the Institut des Hautes Études Scientifiques (IHES) welcomed the news of the first observation of gravitational waves emitted by a black hole binary system by the two US LIGO interferometers from the LIGO/Virgo international network. The field of gravitational wave astronomy that these observations give birth to will make extraordinary progress and the Institute hopes to contribute to analysing the data it will provide on the cosmos, black hole physics and, more generally, on the new Universe invented by Einstein a century ago.
