Gravitational waveforms from SpEC simulations : neutron star-neutron star and low-mass black hole-neutron star binaries
Francois Foucart, Matthew D. Duez, Tanja Hinderer +9
Gravitational waveforms from numerical simulations are a critical tool to test and analytically calibrate the waveform models used to study the properties of merging compact object…
GW150914 peak frequency: a novel consistency test of strong-field General Relativity
Gregorio Carullo, Gunnar Riemenschneider, Ka Wa Tsang +2
We introduce a novel test of General Relativity in the strong-field regime of a binary black hole coalescence. Combining information coming from Numerical Relativity simulations of…
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…
Waveform systematics for binary neutron star gravitational wave signals: effects of the point-particle baseline and tidal descriptions
Anuradha Samajdar, Tim Dietrich
Gravitational wave (GW) astronomy has consolidated its role as a new observational window to reveal the properties of compact binaries in the Universe. In particular, the discovery…
Search for gravitational waves from a long-lived remnant of the binary neutron star merger GW170817
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1138
One unanswered question about the binary neutron star coalescence GW170817 is the nature of its post-merger remnant. A previous search for post-merger gravitational waves targeted…
Testing the multipole structure of compact binaries using gravitational wave observations
Shilpa Kastha, Anuradha Gupta, K. G. Arun +2
We propose a novel method to test the consistency of the multipole moments of compact binary systems with the predictions of General Relativity (GR). The multipole moments of a com…
Relevance of tidal effects and post-merger dynamics for binary neutron star parameter estimation
Reetika Dudi, Francesco Pannarale, Tim Dietrich +4
Measurements of the properties of binary neutron star systems from gravitational-wave observations require accurate theoretical models for such signals. However, current models are…
Axion star collisions with black holes and neutron stars in full 3D numerical relativity
Katy Clough, Tim Dietrich, Jens C. Niemeyer
Axions are a potential dark matter candidate, which may condense and form self gravitating compact objects, called axion stars (ASs). In this work, we study for the first time head…
Full 3D Numerical Relativity Simulations of Neutron Star -- Boson Star Collisions with BAM
Tim Dietrich, Serguei Ossokine, Katy Clough
With the first direct detections of gravitational waves (GWs) from the coalescence of compact binaries observed by the advanced LIGO and VIRGO interferometers, the era of GW astron…
Gravitational waves and mass ejecta from binary neutron star mergers: Effect of large eccentricities
Swami Vivekanandji Chaurasia, Tim Dietrich, Nathan K. Johnson-McDaniel +3
As current gravitational wave (GW) detectors increase in sensitivity, and particularly as new instruments are being planned, there is the possibility that ground-based GW detectors…
Calibration of Advanced Virgo and Reconstruction of the Gravitational Wave Signal h(t) during the Observing Run O2
Virgo Collaboration, F. Acernese, T. Adams +281
In August 2017, Advanced Virgo joined Advanced LIGO for the end of the O2 run, leading to the first gravitational waves detections with the three-detector network. This paper descr…
Black holes, gravitational waves and fundamental physics: a roadmap
Leor Barack, Vitor Cardoso, Samaya Nissanke +203
The grand challenges of contemporary fundamental physics---dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-…
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…
Empirical tests of the black hole no-hair conjecture using gravitational-wave observations
Gregorio Carullo, Laura van der Schaaf, Lionel London +10
We show that second-generation gravitational-wave detectors at their design sensitivity will allow us to directly probe the ringdown phase of binary black hole coalescences. This o…
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…
