An increased estimate of the merger rate of double neutron stars from observations of a highly relativistic system
This work reports the discovery of a 22-ms pulsar, PSR J0737–3039, which is a member of a highly relativistic double-neutron-star binary with an orbital period of 2.4 hours, which implies an order-of-magnitude increase in the predicted merger rate for double- NEUTron- star systems in the authors' Galaxy (and in the rest of the Universe).
The discovery of the gravitational-wave source GW150914 with the Advanced LIGO detectors provides the first observational evidence for the existence of binary black-hole systems that inspiral and
Binary Black Hole Mergers in the First Advanced LIGO Observing Run
The first observational run of the Advanced LIGO detectors, from September 12, 2015 to January 19, 2016, saw the first detections of gravitational waves from binary black hole mergers. In this paper
GW190814: Gravitational Waves from the Coalescence of a 23 Solar Mass Black Hole with a 2.6 Solar Mass Compact Object
We report the observation of a compact binary coalescence involving a 22.2–24.3 M ⊙ black hole and a compact object with a mass of 2.50–2.67 M ⊙ (all measurements quoted at the 90% credible level).
The Rate of Binary Black Hole Mergers Inferred from Advanced LIGO Observations Surrounding GW150914
A transient gravitational-wave signal, GW150914, was identified in the twin Advanced LIGO detectors on September 14, 2015 at 09:50:45 UTC. To assess the implications of this discovery, the detectors
Host Galaxies Catalog Used in LIGO Searches for Compact Binary Coalescence Events
An up-to-date catalog of nearby galaxies considered to be hosts of binary compact objects is provided, with complete information about sky position, distance, extinction-corrected blue luminosity,
Parameter estimation for compact binaries with ground-based gravitational-wave observations using the LALInference software library
This work describes the LALInference software library for Bayesian parameter estimation of compact binary signals, which builds on several previous methods to provide a well-tested toolkit which has already been used for several studies.
Prospects for observing and localizing gravitational-wave transients with Advanced LIGO, Advanced Virgo and KAGRA
The sensitivity of the LIGO network to transient gravitational-wave signals is estimated, and the capability of the network to determine the sky location of the source is studied, to facilitate planning for multi-messenger astronomy with gravitational waves.
Exploring the Sensitivity of Next Generation Gravitational Wave Detectors
The second-generation of gravitational-wave detectors are just starting operation, and have already yielding their first detections. Research is now concentrated on how to maximize the scientific
Population Properties of Compact Objects from the Second LIGO–Virgo Gravitational-Wave Transient Catalog
We report on the population of 47 compact binary mergers detected with a false-alarm rate of < in the second LIGO–Virgo Gravitational-Wave Transient Catalog. We observe several characteristics of the
