Binary Black Hole Population Properties Inferred from the First and Second Observing Runs of Advanced LIGO and Advanced Virgo
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1138
We present results on the mass, spin, and redshift distributions with phenomenological population models using the ten binary black hole mergers detected in the first and second ob…
GWTC-1: A Gravitational-Wave Transient Catalog of Compact Binary Mergers Observed by LIGO and Virgo during the First and Second Observing Runs
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1148
We present the results from three gravitational-wave searches for coalescing compact binaries with component masses above 1 during the first and second observing…
Observing the post-merger signal of GW170817-like events with improved gravitational-wave detectors
Andoni Torres-Rivas, Katerina Chatziioannou, Andreas Bauswein +1
The recent detection of a neutron star binary through gravitational waves, GW170817, has offered another source of information about the properties of cold supranuclear matter. Inf…
Tests of General Relativity with GW170817
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1145
The recent discovery by Advanced LIGO and Advanced Virgo of a gravitational wave signal from a binary neutron star inspiral has enabled tests of general relativity (GR) with this n…
Phenomenological model for the gravitational-wave signal from precessing binary black holes with two-spin effects
Sebastian Khan, Katerina Chatziioannou, Mark Hannam +1
The properties of compact binaries, such as masses and spins, are imprinted in the gravitational-waves they emit and can be measured using parameterised waveform models. Accurately…
Constraining the p-mode--g-mode tidal instability with GW170817
The LIGO Scientific Collaboration, The Virgo Collaboration, B. P. Abbott +1136
We analyze the impact of a proposed tidal instability coupling -modes and -modes within neutron stars on GW170817. This non-resonant instability transfers energy from the orb…
Identifying a first-order phase transition in neutron star mergers through gravitational waves
Andreas Bauswein, Niels-Uwe F. Bastian, David B. Blaschke +4
We identify an observable imprint of a first-order hadron-quark phase transition at supranuclear densities on the gravitational-wave (GW) emission of neutron star mergers. Specific…
Mitigation of the instrumental noise transient in gravitational-wave data surrounding GW170817
Chris Pankow, Katerina Chatziioannou, Eve A. Chase +9
In the coming years gravitational-wave detectors will undergo a series of improvements, with an increase in their detection rate by about an order of magnitude. Routine detections…
A standard siren measurement of the Hubble constant from GW170817 without the electromagnetic counterpart
M. Fishbach, R. Gray, I. Magaña Hernandez +316
We perform a statistical standard siren analysis of GW170817. Our analysis does not utilize knowledge of NGC 4993 as the unique host galaxy of the optical counterpart to GW170817.…
Measuring the neutron star tidal deformability with equation-of-state-independent relations and gravitational waves
Katerina Chatziioannou, Carl-Johan Haster, Aaron Zimmerman
Gravitational wave measurements of binary neutron star coalescences offer information about the properties of the extreme matter that comprises the stars. Despite our expectation t…
GW170817: Measurements of Neutron Star Radii and Equation of State
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1149
On 17 August 2017, the LIGO and Virgo observatories made the first direct detection of gravitational waves from the coalescence of a neutron star binary system. The detection of th…
Properties of the binary neutron star merger GW170817
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1148
On August 17, 2017, the Advanced LIGO and Advanced Virgo gravitational-wave detectors observed a low-mass compact binary inspiral. The initial sky localization of the source of the…
A morphology-independent data analysis method for detecting and characterizing gravitational wave echoes
Ka Wa Tsang, Michiel Rollier, Archisman Ghosh +6
The ability to directly detect gravitational waves has enabled us to empirically probe the nature of ultra-compact relativistic objects. Several alternatives to the black holes of…
Measuring the properties of nearly extremal black holes with gravitational waves
Katerina Chatziioannou, Geoffrey Lovelace, Michael Boyle +7
Characterizing the properties of black holes is one of the most important science objectives for gravitational-wave observations. Astrophysical evidence suggests that black holes t…
