Rapid localization of gravitational wave sources from compact binary coalescences using deep learning

This paper proposes the first deep learning-based approach for rapid and accurate sky localization of all types of binary coalescences, including neutron star-neutron star and neutronStar-black hole binaries for the first time.



Prospects for Observing and Localizing Gravitational-Wave Transients with Advanced LIGO and Advanced Virgo

A possible observing scenario for the Advanced LIGO and Advanced Virgo gravitational-wave detectors over the next decade is presented, and the expected sensitivity of the network to transient gravitational- wave signals is determined, and its capability to determine the sky location of the source is studied.

Characterization of the LIGO detectors during their sixth science run

In 2009–2010, the Laser Interferometer Gravitational-Wave Observatory (LIGO) operated together with international partners Virgo and GEO600 as a network to search for gravitational waves (GWs) of

Advanced Virgo: a second-generation interferometric gravitational wave detector

Advanced Virgo is the project to upgrade the Virgo interferometric detector of gravitational waves, with the aim of increasing the number of observable galaxies (and thus the detection rate) by three

On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced

Gravitational Waves and Gamma-Rays from a Binary Neutron Star Merger: GW170817 and GRB 170817A

On 2017 August 17, the gravitational-wave event GW170817 was observed by the Advanced LIGO and Virgo detectors, and the gamma-ray burst (GRB) GRB 170817A was observed independently by the Fermi

Capturing the electromagnetic counterparts of binary neutron star mergers through low-latency gravitational wave triggers

We investigate the prospects for joint low-latency gravitational wave (GW) detection and prompt electromagnetic (EM) follow-up observations of coalescing binary neutron stars (BNSs). For BNS mergers

GWTC-2.1: Deep Extended Catalog of Compact Binary Coalescences Observed by LIGO and Virgo During the First Half of the Third Observing Run

The second Gravitational-Wave Transient Catalog, GWTC-2, reported on 39 compact binary coalescences observed by the Advanced LIGO and Advanced Virgo detectors between 1 April 2019 15:00 UTC and 1

Sub-threshold Binary Neutron Star Search in Advanced LIGO’s First Observing Run

We present a search for gravitational waves from double neutron star binaries inspirals in Advanced Laser Interferometer Gravitational-Wave Observatory’s (LIGO’s) first observing run. The search

3-OGC: Catalog of Gravitational Waves from Compact-binary Mergers

We present the third open gravitational-wave catalog (3-OGC) of compact-binary coalescences, based on the analysis of the public LIGO and Virgo data from 2015 through 2019 (O1, O2, O3a). Our updated

INTEGRAL Detection of the First Prompt Gamma-Ray Signal Coincident with the Gravitational-wave Event GW170817

We report the INTernational Gamma-ray Astrophysics Laboratory (INTEGRAL) detection of the short gamma-ray burst GRB 170817A (discovered by Fermi-GBM) with a signal-to-noise ratio of 4.6, and, for the
