Un hologramme dans le spectromètre de LSST
Résumé Nous avons réalisé un hologramme pour le télescope auxiliaire de LSST, qui améliorera les mesures de la transparence de l’atmosphère en fonction de la longueur d’onde. Le gain apporté…
Constraints on cosmic strings using data from the third Advanced LIGO-Virgo observing run
Abstract: (APS) We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 dataset. Search results are presented for gravitational waves produced by cosmic…

GRANDMA observations of advanced LIGO’s and advanced Virgo’s third observational campaign
Abstract: (Oxford University Press) GRANDMA (Global Rapid Advanced Network Devoted to the Multi-messenger Addicts) is a network of 25 telescopes of different sizes, including both photometric and spectroscopic facilities. The…
Gravitational-wave Merger Forecasting: Scenarios for the Early Detection and Localization of Compact-binary Mergers with Ground-based Observatories
Abstract: (IOP) We present the prospects for the early (pre-merger) detection and localization of compact-binary coalescences using gravitational waves over the next 10 yr. Early warning can enable the direct…
GW190521: A Binary Black Hole Merger with a Total Mass of 150 M⊙
Abstract: (APS) On May 21, 2019 at 03:02:29 UTC Advanced LIGO and Advanced Virgo observed a short duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise ratio of 14.7, and…
Realtime search for compact binary mergers in Advanced LIGO and Virgo’s third observing run using PyCBC Live
Abstract: (arXiv) The third observing run of Advanced LIGO and Advanced Virgo took place between April 2019 and March 2020 and resulted in dozens of gravitational-wave candidates, many of which…
Omicron: a tool to characterize transient noise in gravitational-wave detectors
The Omicron software is a tool developed to perform a multi-resolution time-frequency analysis of data from gravitational-wave detectors: the LIGO, Virgo, and KAGRA detectors. Omicron generates spectrograms from whitened data…
The first six months of the Advanced LIGO’s and Advanced Virgo’s third observing run with GRANDMA
Abstract: (Oxford University Press) We present the Global Rapid Advanced Network Devoted to the Multi-messenger Addicts (GRANDMA). The network consists of 21 telescopes with both photometric and spectroscopic facilities. They…
