Impact of modelling galaxy redshift uncertainties on the gravitational-wave dark standard siren measurement of the Hubble constant
Cezary Turski, Maciej Bilicki, Gergely Dálya +2
Gravitational wave science is a new and rapidly expanding field of observational astronomy. Multimessenger observations of the binary neutron star merger GW170817 have provided som…
The Hitchhiker's guide to the galaxy catalog approach for gravitational wave cosmology
Jonathan R. Gair, Archisman Ghosh, Rachel Gray +28
We outline the ``dark siren'' galaxy catalog method for cosmological inference using gravitational wave (GW) standard sirens, clarifying some common misconceptions in the implement…
Cosmology in the dark: How compact binaries formation impact the gravitational-waves cosmological measurements
S. Mastrogiovanni, K. Leyde, C. Karathanasis +7
Information about the mass spectrum of compact stars can be used to infer cosmological parameters from gravitational waves (GW) in the absence of redshift measurements obtained fro…
Search for lensing signatures in the gravitational-wave observations from the first half of LIGO-Virgo's third observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1378
We search for signatures of gravitational lensing in the gravitational-wave signals from compact binary coalescences detected by Advanced LIGO and Advanced Virgo during O3a, the fi…
Cosmology in the dark: On the importance of source population models for gravitational-wave cosmology
S. Mastrogiovanni, K. Leyde, C. Karathanasis +7
Knowledge of the shape of the mass spectrum of compact objects can be used to help break the degeneracy between the mass and redshift of the gravitational wave (GW) sources, and th…
GWTC-2: Compact Binary Coalescences Observed by LIGO and Virgo During the First Half of the Third Observing Run
R. Abbott, T. D. Abbott, S. Abraham +1349
We report on gravitational wave discoveries from compact binary coalescences detected by Advanced LIGO and Advanced Virgo in the first half of the third observing run (O3a) between…
GW190521: A Binary Black Hole Merger with a Total Mass of
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1253
On May 21, 2019 at 03:02:29 UTC Advanced LIGO and Advanced Virgo observed a short duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise ratio…
Summary of Tests of General Relativity with the Binary Black Hole Signals from the LIGO-Virgo Catalog GWTC-1
Nathan K. Johnson-McDaniel
We summarize the four tests of general relativity carried out using the ten binary black hole signals detected by Advanced LIGO and Advanced Virgo and included in their first catal…
All-sky search for long-duration gravitational-wave transients in the second Advanced LIGO observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1183
We present the results of a search for long-duration gravitational-wave transients in the data from the Advanced LIGO second observation run; we search for gravitational-wave trans…
Tests of General Relativity with the Binary Black Hole Signals from the LIGO-Virgo Catalog GWTC-1
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1142
The detection of gravitational waves by Advanced LIGO and Advanced Virgo provides an opportunity to test general relativity in a regime that is inaccessible to traditional astronom…
Search for the isotropic stochastic background using data from Advanced LIGO's second observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1133
The stochastic gravitational-wave background is a superposition of sources that are either too weak or too numerous to detect individually. In this study we present the results fro…
