Abstract We perform a statistical standard siren analysis of GW170817. Our does not utilize knowledge NGC 4993 as the unique host galaxy optical counterpart to Instead, we consider each within GW170817 localization region potential host; combining redshifts from all galaxies with distance estimate provides an Hubble constant, H 0 . Considering brighter than equally likely binary neutron star merger, find km s −1 Mpc (maximum posteriori and 68.3% highest density posterior interval; assuming...
In August 2017, Advanced Virgo joined LIGO for the end of O2 run, leading to first gravitational waves detections with three-detector network. This paper describes calibration and wave strain h(t) reconstruction during O2. The methods are same as ones developed initial detector have already been described in previous publications, this summarizes differences emphasis is put on estimating systematic uncertainties. Three versions signal computed an online version two post-run reprocessed...
Abstract The detection of a gravitational wave signal in September 2015 by LIGO interferometers, announced jointly collaboration and Virgo February 2016, opened new era Astrophysics brought to the whole community way look at - or “listen” Universe. In this regard, next big step was joint observation with least three detectors same time. This configuration provides twofold benefit: it increases signal-to-noise ratio events means triple coincidence allows narrower pinpointing GW sources, and,...
The LIGO and the Virgo collaborations have recently announced first detections of Gravitational Waves. Due to their weak amplitude, Waves are expected produce a very small effect on free-falling masses, which undergo displacement order 10 -18 m for Km-scale mutual distance. This discovery showed that interferometric detectors suitable reveal such feeble effect, therefore represent new tool astronomy, astrophysics cosmology in understanding Universe. To better reconstruct position Wave source...
Advanced Virgo is the French–Italian second generation laser gravitational wave detector, successor of Initial Virgo. This new interferometer keeps only infrastructure its predecessor and aims to be ten times more sensitive, with first science run planned for 2017. article gives an overview design technical choices behind it. Finally, up-to-date progresses upgrade following years are detailed.
Advanced Virgo is the French-Italian second generation laser gravitational wave detector, successor of Initial Virgo.This new interferometer keeps only infrastructure its predecessor and aims to be 10 times more sensitive, with first science run planned for 2017.This article gives an overview design technical choices behind it.Finally, up-to-date progresses upgrade following years are detailed.
The Advanced Virgo project was funded in 2009 with the aim of improving sensitivity interferometric detector for gravitational waves by a factor ten, which corresponds to an increase detection rate about three orders magnitude.The upgrade is now close completion: new interferometer will enter its commissioning phase 2016.The be hosted same infrastructure as Virgo, but many technological upgrades have been put place reach goal.In this paper design and observational perspectives are discussed.
