All-sky search for continuous gravitational waves from isolated neutron stars using Advanced LIGO and Advanced Virgo O3 data

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

We present results of an all-sky search for continuous gravitational waves which can be produced by spinning neutron stars with an asymmetry around their rotation axis, using data from the third observing run of the Advanced LIGO and Advanced Virgo detectors. Four …

Search for gravitational-wave transients associated with magnetar bursts in Advanced LIGO and Advanced Virgo data from the third observing run

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

Gravitational waves are expected to be produced from neutron star oscillations associated with magnetar giant flares and short bursts. We present the results of a search for short-duration (milliseconds to seconds) and long-duration ($\sim$ 100 s) transient gravitational waves from 13 magnetar …

First joint observation by the underground gravitational-wave detector KAGRA with GEO 600

H. Abe, F. Acernese, K. Ackley, R. X. Adhikari et autres

Abstract We report the results of the first joint observation of the KAGRA detector with GEO 600. KAGRA is a cryogenic and underground gravitational-wave detector consisting of a laser interferometer with 3 km arms, located in Kamioka, Gifu, Japan. GEO 600 is …

All-sky search for short gravitational-wave bursts in the third Advanced LIGO and Advanced Virgo run

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

This paper presents the results of a search for generic short-duration gravitational-wave transients in data from the third observing run of Advanced LIGO and Advanced Virgo. Transients with durations of milliseconds to a few seconds in the 24--4096 Hz frequency band are …

Searches for Continuous Gravitational Waves from Young Supernova Remnants in the Early Third Observing Run of Advanced LIGO and Virgo

R. Abbott, T. D. Abbott, S. Abraham, F. Acernese et autres

Abstract We present results of three wide-band directed searches for continuous gravitational waves from 15 young supernova remnants in the first half of the third Advanced LIGO and Virgo observing run. We use three search pipelines with distinct signal models and methods …

All-sky search for continuous gravitational waves from isolated neutron stars in the early O3 LIGO data

R. Abbott, T. D. Abbott, S. Abraham, F. Acernese et autres

We report on an all-sky search for continuous gravitational waves in the frequency band 20--2000 Hz and with a frequency time derivative in the range of $[\ensuremath{-}1.0,+0.1]\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}8}\text{ }\text{ }\mathrm{Hz}/\mathrm{s}$. Such a signal could be produced by a nearby, spinning and slightly nonaxisymmetric …

Upper limits on the isotropic gravitational-wave background from Advanced LIGO and Advanced Virgo’s third observing run

R. Abbott, T. D. Abbott, S. Abraham, F. Acernese et autres

We report results of a search for an isotropic gravitational-wave background (GWB) using data from Advanced LIGO's and Advanced Virgo's third observing run (O3) combined with upper limits from the earlier O1 and O2 runs. Unlike in previous observing runs in the …

All-sky search in early O3 LIGO data for continuous gravitational-wave signals from unknown neutron stars in binary systems

R. Abbott, T. D. Abbott, S. Abraham, F. Acernese et autres

Rapidly spinning neutron stars are promising sources of continuous gravitational waves. Detecting such a signal would allow probing of the physical properties of matter under extreme conditions. A significant fraction of the known pulsar population belongs to binary systems. Searching for unknown …

Optically targeted search for gravitational waves emitted by core-collapse supernovae during the first and second observing runs of advanced LIGO and advanced Virgo

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

We present the results from a search for gravitational-wave transients associated with core-collapse supernovae observed within a source distance of approximately 20 Mpc during the first and second observing runs of Advanced LIGO and Advanced Virgo. No significant gravitational-wave candidate was detected. …
