We describe the observation of GW170104, a gravitational-wave signal produced by the coalescence of a pair of stellar-mass black holes. The signal was measured on January 4, 2017 at 10âˆ¶11:58.6 UTC by the twin advanced detectors of the Laser Interferometer Gravitational-Wave Observatory during their second observing run, with a network signal-to-noise ratioâ€¦ (More)

We consider the spacetime of a perfect fluid described by the Einstein-Euler equations. We assume given spatial growth for the fluid and spacetime initial data and estimate the temporal evolution of the spatial growth rates through the wave equations derived for the fluid and spacetime data.

On August 17, 2017 at 12âˆ¶41:04 UTC the Advanced LIGO and Advanced Virgo gravitational-wave detectors made their first observation of a binary neutron star inspiral. The signal, GW170817, was detected with a combined signal-to-noise ratio of 32.4 and a false-alarm-rate estimate of less than one per 8.0Ã—10^{4}â€‰â€‰years. We infer the component masses of theâ€¦ (More)

On August 14, 2017 at 10âˆ¶30:43 UTC, the Advanced Virgo detector and the two Advanced LIGO detectors coherently observed a transient gravitational-wave signal produced by the coalescence of two stellar mass black holes, with a false-alarm rate of â‰²1 in 27 000Â years. The signal was observed with a three-detector network matched-filter signal-to-noise ratio ofâ€¦ (More)

Binary systems of two compact objects circularize and spiral toward each other via the emission of gravitational waves. The coupling of the spins of each object with the orbital angular momentum causes the orbital plane to precess, which leads to modulation of the gravitational wave signal. Until now, generating frequency-domain waveforms for fullyâ€¦ (More)

We present the results of a semicoherent search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1, using data from the first Advanced LIGO observing run. The search method uses details of the modeled, parametrized continuous signal to combine coherently data separated by less than a specified coherence time, which can beâ€¦ (More)

The purpose of this work is to highlight the importance of the calculation of the nonlinear extreme wave kinematics appropriate for load calculations of the elements of a platform in deep water. Numerical calculations have been undertaken using a fully nonlinear three-dimensional wave model capable of accurately representing a realistic distribution of waveâ€¦ (More)
