Searching for a Stochastic Background of Gravitational Waves with the Laser Interferometer Gravitational-Wave Observatory

B. Abbott, R. Abbott, R. X. Adhikari, J. Agresti et autres

The Laser Interferometer Gravitational-Wave Observatory (LIGO) has performed the fourth science run, S4, with significantly improved interferometer sensitivities with respect to previous runs. Using data acquired during this science run, we place a limit on the amplitude of a stochastic background of …

THE LIGO GRAVITATIONAL WAVE OBSERVATORIES: RECENT RESULTS AND FUTURE PLANS

Ian W Harry, R. X. Adhikari, S. W. Ballmer, K. Bayer et autres

The LIGO interferometers are operating as gravitational wave observatories, with a noise level near an order of magnitude of the goal and the first scientific data recently taken.This data has been analyzed for four different categories of gravitational wave sources; millisecond bursts, …

Upper Limits on a Stochastic Background of Gravitational Waves

B. Abbott, R. Abbott, R. X. Adhikari, J. Agresti et autres

The Laser Interferometer Gravitational-Wave Observatory has performed a third science run with much improved sensitivities of all three interferometers. We present an analysis of approximately 200 hours of data acquired during this run, used to search for a stochastic background of gravitational …

Upper limits on the strength of periodic gravitational waves from PSR J1939+2134

B. Allen, G. Woan, B. Abbott, R. Abbott et autres

The first science run of the LIGO and GEO gravitational wave detectors presented the opportunity to test methods of searching for gravitational waves from known pulsars. Here we present new direct upper limits on the strength of waves from the pulsar PSR …
