TL;DR: The VIRGO Central Interferometer (CITF) as mentioned in this paper is a short suspended interferometer operated with the central area elements of the VRGO detector, which allows the integration and debugging of a large part of the subsystems of the detector while the long arms of the antenna is being completed.

TL;DR: In this article, 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.

TL;DR: In this article, the authors performed a standard siren analysis of GW170817 and found that all galaxies brighter than 0.01 L^\star_B$ are equally likely to host a BNS merger.

TL;DR: In this article, the authors describe directed searches for continuous gravitational waves in data from the sixth LIGO science data run, where the targets were nine young supernova remnants not associated with pulsars; eight of the remnants are associated with non-pulsing suspected neutron stars.

TL;DR: In this article, direct upper limits on continuous gravitational wave emission from the Vela pulsar using data from the Virgo detector's second science run were obtained using three independent methods.
