Abstract
On September 14, 2015, almost 60 years after Joseph Weber’s first proposal of resonant bar detectors for picking up gravitational waves (Weber 1960), the two American interferometric antennas comprising LIGO (Laser Interferometer Gravitational Observatory) recorded the first detection of a gravitational wave signal. A chirping waveform lasting about two-tenths of a second with a frequency spanning rapidly from 35 Hz to 250 Hz hit the detector in Livingston, Louisiana, and about 7 ms later, the one in Hanford, Washington, 3000 km away| File | Dimensione | Formato | |
