报告摘要：

On the 14th of September 2015, the Advanced LIGO made the first detection of gravitational waves. The observed signal, which originated from the coalescence and merger of two binary black holes, heralded the dawn of gravitational wave astronomy. Since then, gravitational waves from several more binary black hole coalescences have been detected by Advanced LIGO and Advanced Virgo. This talk will give a brief overview of gravitational waves as well as the Advanced LIGO and Advanced Virgo gravitational wave detectors before describing the multiple detection of gravitational waves. The properties of the observed signals will be presented and the implications of these detections discussed. Finally, prospects for binary neutron star detections and multi-messenger astronomy, which combine gravitational wave observations with gamma-ray, X-ray, optical, etc observations, are discussed.
