Description
The new era of gravitational wave astronomy started with the discovery of the gravitational-wave source GW150914 by the LIGO and Virgo collaborations.
The signal provides the first observational evidence of the inspiral and merger of binary black holes and the existence of black holes with mass larger than 25 solar masses. Electromagnetic and high-energy-neutrino follow-up observations have been performed marking the beginning of hystorical multi-messenger astronomy
with gravitational waves. The talk will summarize the astrophysical implications of the discovery and the multi-messenger follow-up campaign of GW150914.
