- Abstract:
- The gravitational waves were detected directly for the first time on September 14 at 18:51 (Korean Standard Time) by twin LIGO detectors located at Livingston, Louisiana and Hanford, Washington nearly simultaneously. This event was found to have been produced during the last fraction of second of the inspiral and merger of a binary system composed of two black holes of about 39 and 26 Msun each, located at about 400 Mpc. During this process, huge amount of energy corresponding to approximately 3 Msun in the form of gravitational waves has been radiated away, leaving a single black hole of about 62 solar mass behind. In this talk, I will briefly describe the nature of the nature of gravitational waves, the principle of the LIGO detectors and their sensitivities, and how actual detection was made. Then I will close my talk by commenting on the astrophysical implications and the prospects of the gravitational wave astronomy brought by this detection

- I have changed the sentences starting with 'we ..' to 'This event was found to be produced ...'.
