For 17 days in August and September 2002, the LIGO and GEO interferometer gravitational wave detectors were operated in coincidence to produce their first data for scientific analysis. Although the detectors were still far from their design sensitivity levels, the data can be used to place better upper limits on the flux of gravitational waves incident on the earth than previous direct measurements. This paper describes the instruments and the data in some detail, as a companion to analysis papers based on the first data.

    • "The ground-based gravitational-wave detectors are rapidly increasing their sensitivities. The first generation detectors LIGO [1] [2] and Virgo [3] [4] have reached their design sensitivities and collected excellent data over several years of exposure. The second generation detectors , Advanced LIGO [5] [6], Advanced Virgo [7], GEO- HF [8], and LCGT [9] [10] are currently being built and commissioned. "

    ABSTRACT: Compact binary coalescences, such as binary neutron stars or black holes, are among the most promising candidate sources for the current and future terrestrial gravitational-wave detectors. While such sources are best searched using matched template techniques and chirp template banks, integrating chirp signals from binaries over the entire Universe also leads to a gravitational-wave background (GWB). In this paper we systematically scan the parameter space for the binary coalescence GWB models, taking into account uncertainties in the star formation rate and in the delay time between the formation and coalescence of the binary, and we compare the computed GWB to the sensitivities of the second and third generation gravitational-wave detector networks. We find that second generation detectors are likely to detect the binary coalescence GWB, while the third generation detectors will probe most of the available parameter space. The binary coalescence GWB will, in fact, be a foreground for the third-generation detectors, potentially masking the GWB background due to cosmological sources. Accessing the cosmological GWB with third generation detectors will therefore require identification and subtraction of all inspiral signals from all binaries in the detectors' frequency band.

    • "The length between the test masses will be controlled by applying forces on the masses to keep the photodiode signal locked on a dark fringe. This makes BBO more like a ground-based interferometer such as LIGO [5] [4] than LISA. LISA employs heterodyne interferometry based on offset lasers, and thus has no 'dark-fringe' position. "

    ABSTRACT: The Big Bang Observer is a proposed space-based gravitational-wave detector intended as a follow on mission to the Laser Interferometer Space Antenna (LISA). It is designed to detect the stochastic background of gravitational waves from the early universe. We discuss how the interferometry can be arranged between three spacecraft for this mission and what research and development on key technologies are necessary to realize this scheme.

    ABSTRACT: LIGO is dedicated to the detection of gravitational waves. To achieve the design sensitivity of the proposed Advanced LIGO detectors, the seismic isolation system is required to isolate the interferometer mirrors from ground motion above 0.1 Hz. The dominant source of motion above 0.1 Hz is the microseismic peaks near 0.15 Hz. The system needs to isolate the payload from this motion by at least a factor of five in all three translational degrees of freedom. Tilt-horizontal coupling is the most challenging problem for seismic isolation below 1 Hz. Tilt-horizontal coupling results from the principle of equivalence: inertial horizontal sensors cannot distinguish horizontal ac-celeration from tilt motion. Tilt-horizontal coupling rises dramatically at low frequencies, which makes low frequency isolation difficult. Several techniques are used to address the tilt-horizontal coupling problem. The isolation platform is designed to separate horizontal motions from tilt motions. Feedback control to displacement sensors is used to command the platform in all degrees of freedom. These sensors are "corrected" by ground seismometers, using an optimal FIR filtering technique to separate tilt noise from horizontal acceleration. With these techniques, we obtained isolation factors of 10 to 20 simultaneously in all three degrees of freedom at 0.15 Hz.
