Joint LIGO and TAMA300 search for gravitational waves from inspiralling neutron star binaries

B. Abbott, R. Abbott, R. X. Adhikari, A. Ageev et autres

We search for coincident gravitational wave signals from inspiralling neutron star binaries using LIGO and TAMA300 data taken during early 2003. Using a simple trigger exchange method, we perform an intercollaboration coincidence search during times when TAMA300 and only one of the …

Search for gravitational waves from binary black hole inspirals in LIGO data

B. Abbott, R. Abbott, R. X. Adhikari, A. Ageev et autres

We report on a search for gravitational waves from binary black hole inspirals in the data from the second science run of the LIGO interferometers. The search focused on binary systems with component masses between 3 and $20{M}_{\ensuremath{\bigodot}}$. Optimally oriented binaries with …

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 from the LIGO and TAMA detectors on the rate of gravitational-wave bursts

B. Abbott, R. Abbott, R. X. Adhikari, A. Ageev et autres

We report on the first joint search for gravitational waves by the TAMA and LIGO collaborations. We looked for millisecond-duration unmodeled gravitational-wave bursts in 473 hr of coincident data collected during early 2003. No candidate signals were found. We set an upper …

First all-sky upper limits from LIGO on the strength of periodic gravitational waves using the Hough transform

B. Abbott, R. Abbott, R. X. Adhikari, A. Ageev et autres

We perform a wide parameter-space search for continuous gravitational waves over the whole sky and over a large range of values of the frequency and the first spin-down parameter. Our search method is based on the Hough transform, which is a semicoherent, …

Search for gravitational waves from primordial black hole binary coalescences in the galactic halo

B. Abbott, R. Abbott, R. X. Adhikari, A. Ageev et autres

We use data from the second science run of the LIGO gravitational-wave detectors to search for the gravitational waves from primordial black hole binary coalescence with component masses in the range $0.2--1.0{M}_{\ensuremath{\bigodot}}$. The analysis requires a signal to be found in the …

Search for gravitational waves from galactic and extra-galactic binary neutron stars

B. Abbott, R. Abbott, R. X. Adhikari, A. Ageev et autres

We use 373 hours ($\ensuremath{\approx}15$ days) of data from the second science run of the LIGO gravitational-wave detectors to search for signals from binary neutron star coalescences within a maximum distance of about 1.5 Mpc, a volume of space which includes the …

Upper limits on gravitational wave bursts in LIGO’s second science run

B. Abbott, R. Abbott, R. X. Adhikari, A. Ageev et autres

We perform a search for gravitational wave bursts using data from the second science run of the LIGO detectors, using a method based on a wavelet time-frequency decomposition. This search is sensitive to bursts of duration much less than a second and …

Search for gravitational waves associated with the gamma ray burst GRB030329 using the LIGO detectors

B. Abbott, R. Abbott, R. X. Adhikari, A. Ageev et autres

We have performed a search for bursts of gravitational waves associated with the very bright gamma ray burst GRB030329, using the two detectors at the LIGO Hanford Observatory. Our search covered the most sensitive frequency range of the LIGO detectors (approximately $80--\ensuremath{-}2048\text{ …

Limits on Gravitational-Wave Emission from Selected Pulsars Using LIGO Data

B. Abbott, R. Abbott, R. X. Adhikari, A. Ageev et autres

We place direct upper limits on the amplitude of gravitational waves from 28 isolated radio pulsars by a coherent multidetector analysis of the data collected during the second science run of the LIGO interferometric detectors. These are the first direct upper limits …

Analysis of LIGO data for gravitational waves from binary neutron stars

B. Abbott, R. Abbott, R. X. Adhikari, A. Ageev et autres

We report on a search for gravitational waves from coalescing compact binary systems in the Milky Way and the Magellanic Clouds. The analysis uses data taken by two of the three LIGO interferometers during the first LIGO science run and illustrates a …
