Virgo detector characterization and data quality: results from the O3 run

F. Acernese, M. Agathos, A. Ain, S. Albanesi et autres

Abstract The Advanced Virgo detector has contributed with its data to the rapid growth of the number of detected GW signals in the past few years, alongside the two Advanced LIGO instruments. First during the last month of the Observation Run 2 …

Search for gravitational-lensing signatures in the full third observing run of the LIGO-Virgo network

The LIGO Scientific Collaboration, the KAGRA Collaboration, R. Abbott, H. Abe et autres

Gravitational lensing by massive objects along the line of sight to the source causes distortions of gravitational wave-signals; such distortions may reveal information about fundamental physics, cosmology and astrophysics. In this work, we have extended the search for lensing signatures to all …

Search for intermediate-mass black hole binaries in the third observing run of Advanced LIGO and Advanced Virgo

R. Abbott, T. D. Abbott, F. Acernese, K. Ackley et autres

Intermediate-mass black holes (IMBHs) span the approximate mass range 100−105 M⊙, between black holes (BHs) that formed by stellar collapse and the supermassive BHs at the centers of galaxies. Mergers of IMBH binaries are the most energetic gravitational-wave sources accessible by the …

GW170104: Observation of a 50-Solar-Mass Binary Black Hole Coalescence at Redshift 0.2

B. P. Abbott, R. Abbott, T. D. Abbott, F. Acernese et autres

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 10∶11:58.6 UTC by the twin advanced detectors of the Laser Interferometer Gravitational-Wave Observatory …

Characterization of the Virgo Seismic Environment

T. Accadia, F. Acernese, P. Astone, G. Ballardin et autres

The Virgo gravitational wave detector is an interferometer (ITF) with 3km arms located in Pisa, Italy. From July to October 2010, Virgo performed its third science run (VSR3) in coincidence with the LIGO detectors. Despite several techniques adopted to isolate the interferometer …
