Precision measurements of the magnetic parameters of LISA Pathfinder test masses

M. Armano, H. Audley, J. Baird, Pierre Binétruy et autres

A precise characterization of the magnetic properties of LISA Pathfinder free falling test-masses is of special interest for future gravitational wave observatory in space. Magnetic forces have an important impact on the instrument sensitivity in the low frequency regime below the millihertz. …

Nano-Newton electrostatic force actuators for femto-Newton-sensitive measurements: System performance test in the LISA Pathfinder mission

M. Armano, H. Audley, J. Baird, Massimo Bassan et autres

Electrostatic force actuation is a key component of the system of geodesic reference test masses (TM) for the LISA orbiting gravitational wave observatory and in particular for performance at low frequencies, below 1 mHz, where the observatory sensitivity is limited by stray …

Model-based Cross-correlation Search for Gravitational Waves from the Low-mass X-Ray Binary Scorpius X-1 in LIGO O3 Data

R. Abbott, Haruka Abe, F. Acernese, K. Ackley et autres

Abstract We present the results of a model-based search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1 using LIGO detector data from the third observing run of Advanced LIGO and Advanced Virgo. This is a semicoherent search that uses …

Tests of General Relativity with GWTC-3

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

The ever-increasing number of detections of gravitational waves (GWs) from compact binaries by the Advanced LIGO and Advanced Virgo detectors allows us to perform ever-more sensitive tests of general relativity (GR) in the dynamical and strong-field regime of gravity. We perform a …

Model comparison from LIGO–Virgo data on GW170817’s binary components and consequences for the merger remnant

B. P. Abbott, R. Abbott, T D Abbott, Sabu Abraham et autres

Abstract GW170817 is the very first observation of gravitational waves originating from the coalescence of two compact objects in the mass range of neutron stars, accompanied by electromagnetic counterparts, and offers an opportunity to directly probe the internal structure of neutron stars. …

A guide to LIGO–Virgo detector noise and extraction of transient gravitational-wave signals

B. P. Abbott, R. Abbott, T D Abbott, Sabu Abraham et autres

The LIGO Scientific Collaboration and the Virgo Collaboration have cataloged eleven confidently detected gravitational-wave events during the first two observing runs of the advanced detector era. All eleven events were consistent with being from well-modeled mergers between compact stellar-mass objects: black holes …

Matrix heater in the gravitational wave observatory GEO 600

H. Wittel, C. Affeldt, A. Bisht, S. Doravari et autres

Large scale laser interferometric gravitational wave detectors (GWDs), such as GEO 600 require high quality optics to reach their design sensitivity. The inevitable surface imperfections, inhomogeneities, and light-absorption induced thermal lensing in the optics, can convert laser light from the fundamental mode …

Constraints on cosmic strings using data from the first Advanced LIGO observing run

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

Cosmic strings are topological defects which can be formed in grand unified theory scale phase transitions in the early universe. They are also predicted to form in the context of string theory. The main mechanism for a network of Nambu-Goto cosmic strings …

Search for gravitational radiation from intermediate mass black hole binaries in data from the second LIGO-Virgo joint science run

J. Aasi, B. P. Abbott, R. Abbott, T D Abbott et autres

This paper reports on an unmodeled, all-sky search for gravitational waves from merging intermediate mass black hole binaries (IMBHB). The search was performed on data from the second joint science run of the LIGO and Virgo detectors (July 2009--October 2010) and was …

Search for gravitational wave ringdowns from perturbed intermediate mass black holes in LIGO-Virgo data from 2005–2010

J. Aasi, B. P. Abbott, R. Abbott, T D Abbott et autres

We report results from a search for gravitational waves produced by perturbed intermediate mass black holes (IMBH) in data collected by LIGO and Virgo between 2005 and 2010. The search was sensitive to astrophysical sources that produced damped sinusoid gravitational wave signals, …

Predictions for the rates of compact binary coalescences observable by ground-based gravitational-wave detectors

J. Abadie, B. P. Abbott, R. Abbott, M. R. Abernathy et autres

We present an up-to-date, comprehensive summary of the rates for all types of compact binary coalescence sources detectable by the initial and advanced versions of the ground-based gravitational-wave detectors LIGO and Virgo. Astrophysical estimates for compact-binary coalescence rates depend on a number …
