Abstract :

On 14th September, 2015, the Laser Interferometer Gravitational-wave Observatory (LIGO) located at Hanford, Washington and Livingston, Louisiana, the United States, detected a gravitational-wave signal coming from the collision of two massive black holes. Around three months later, LIGO detected the gravitational wave again coming from another black hole binary. These discoveries confirmed that Einstein’s prediction in his general relativity was right and implied that massive black hole binaries are frequently merging in the Universe. In this talk, I will introduce the scientists’ persistent efforts and LIGO’s final success for the detection of gravitational waves. And I also would like to introduce the brand new astronomy called ‘gravitational wave astronomy’.
