Journal ArticleDOI

Implementation and testing of the first prompt search for gravitational wave transients with electromagnetic counterparts

J. Abadie, +901 more
TL;DR: In this paper, a low-latency analysis pipeline was used to identify and localize GW event candidates and to reconstruct maps of possible sky locations, and a catalog of nearby galaxies and Milky Way globular clusters were used to select the most promising sky positions to be imaged.
Journal ArticleDOI

Search for Tensor, Vector, and Scalar Polarizations in the Stochastic Gravitational-Wave Background

B. P. Abbott, +1143 more
TL;DR: Using data recorded by Advanced LIGO during its first observing run, no evidence for a background of any polarization is found, and the first direct bounds on the contributions of vector and scalar polarizations to the stochastic background are placed.
Journal ArticleDOI

A theory of gamma-ray bursts

TL;DR: In this article, it was shown that the Blandford-Znajek mechanism of electromagnetic extraction of spin energy from a black hole requires a high angular momentum in the progenitor object.
Journal ArticleDOI

Effects of waveform model systematics on the interpretation of GW150914

B. P. Abbott, +1033 more
TL;DR: In this paper, the effects of possible systematic errors in the waveform models on estimates of its source parameters were investigated and no evidence for a systematic bias relative to the statistical error of the original parameter recovery of GW150914 due to modeling approximations or modeling inaccuracies was found.
Journal ArticleDOI

Gravitational waves from known pulsars: results from the initial detector era

J. Aasi, +894 more
TL;DR: The results of searches for gravitational waves from a large selection of pulsars using data from the most recent science runs (S6, VSR2 and VSR4) of the initial generation of interferometric gravitational wave detectors LIGO (Laser Interferometric Gravitational-wave Observatory) and Virgo as mentioned in this paper.
