Tests of General Relativity with GWTC-3
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1682
The ever-increasing number of detections of gravitational waves (GWs) from compact binaries by the Advanced LIGO and Advanced Virgo detectors allows us to perform ever-more sensiti…
Constraints on the cosmic expansion history from GWTC-3
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1676
We use 47 gravitational-wave sources from the Third LIGO-Virgo-KAGRA Gravitational-Wave Transient Catalog (GWTC-3) to estimate the Hubble parameter , including its current va…
The Next Generation Global Gravitational Wave Observatory: The Science Book
Vicky Kalogera, B. S. Sathyaprakash, Matthew Bailes +88
The next generation of ground-based gravitational-wave detectors will observe coalescences of black holes and neutron stars throughout the cosmos, thousands of them with exceptiona…
Search for Gravitational Waves Associated with Gamma-Ray Bursts Detected by Fermi and Swift During the LIGO-Virgo Run O3b
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1632
We search for gravitational-wave signals associated with gamma-ray bursts detected by the Fermi and Swift satellites during the second half of the third observing run of Advanced L…
The population of merging compact binaries inferred using gravitational waves through GWTC-3
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1634
We report on the population properties of compact binary mergers inferred from gravitational-wave observations of these systems during the first three LIGO-Virgo observing runs. Th…
GWTC-3: Compact Binary Coalescences Observed by LIGO and Virgo During the Second Part of the Third Observing Run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1659
The third Gravitational-Wave Transient Catalog (GWTC-3) describes signals detected with Advanced LIGO and Advanced Virgo up to the end of their third observing run. Updating the pr…
Search for subsolar-mass binaries in the first half of Advanced LIGO and Virgo's third observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1634
We report on a search for compact binary coalescences where at least one binary component has a mass between 0.2 and 1.0 in Advanced LIGO and Advanced Virgo dat…
Uncertainty limits on neutron star radius measurements with gravitational waves
Katerina Chatziioannou
Upcoming observing campaigns with improved detectors will yield numerous detections of gravitational waves from neutron star binary inspirals. Rare loud signals together with numer…
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 LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1429
The second Gravitational-Wave Transient Catalog reported on 39 compact binary coalescences observed by the Advanced LIGO and Advanced Virgo detectors between 1 April 2019 15:00 UTC…
All-sky search for short gravitational-wave bursts in the third Advanced LIGO and Advanced Virgo run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1630
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. Trans…
Impact of the PSR J0740+6620 radius constraint on the properties of high-density matter
Isaac Legred, Katerina Chatziioannou, Reed Essick +2
X-ray pulse profile modeling of PSR J0740+6620, the most massive known pulsar, with data from the NICER and XMM-Newton observatories recently led to a measurement of its radius. We…
A morphology-independent test of the mixed polarization content of gravitational wave signals from compact binary coalescences
Katerina Chatziioannou, Maximiliano Isi, Carl-Johan Haster +1
Gravitational waves in general relativity contain two polarization degrees of freedom, commonly labeled plus and cross. Besides those two tensor modes, generic theories of gravity…
Modeling compact binary signals and instrumental glitches in gravitational wave data
Katerina Chatziioannou, Neil Cornish, Marcella Wijngaarden +1
Transient non-gaussian noise in gravitational wave detectors, commonly referred to as glitches, pose challenges for inference of the astrophysical properties of detected signals wh…
Prospects of gravitational-waves detections from common-envelope evolution with LISA
M. Renzo, T. Callister, K. Chatziioannou +6
Understanding common envelope (CE) evolution is an outstanding problem in binary evolution. Although the CE phase is not driven by gravitational-wave (GW) emission, the in-spiralin…
Constraints on cosmic strings using data from the third Advanced LIGO-Virgo observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1586
We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 data set. Search results are presented for gravitational waves produced b…
