  1. LIGO Gravitational Waves Barry Barish Feb 23, 2000 Lake Louise Winter Institute

  2. LIGO Gravitational Waves Barry Barish Feb 24, 2000 Lake Louise Winter Institute

  3. Gravitational Wavesdirect detection Leslie is an applicant LISA Radiation of Gravitational Waves from binary inspiral system

  4. International Networkinterferometers GEO Virgo TAMA LIGO ACIGA • Simultaneously detect signal (within msec) • detection confidence • locate the sources • decompose polarization of gravitational waves

  5. phase noisesplitting the fringe • Spectral sensitivity of MIT phase noise interferometer • above 500 Hz shot noise limited near LIGO I goal • additional features are from 60 Hz powerline • harnonics, wire resonances (600 Hz), mount • resonances, etc
