Formulation Improvements for Critical Collapse Simulations
Daniela Cors, Sarah Renkhoff, Hannes R. Rüter +2
The precise tuning required to observe critical phenomena in gravitational collapse poses a challenge for most numerical codes. First, threshold estimation searches may be obstruct…
Laying the foundation of the effective-one-body waveform models SEOBNRv5: improved accuracy and efficiency for spinning non-precessing binary black holes
Lorenzo Pompili, Alessandra Buonanno, Héctor Estellés +21
We present SEOBNRv5HM, a more accurate and faster inspiral-merger-ringdown gravitational waveform model for quasi-circular, spinning, nonprecessing binary black holes within the ef…
Investigating GW190425 with numerical-relativity simulations
Reetika Dudi, Ananya Adhikari, Bernd Brügmann +7
The third observing run of the LIGO-Virgo collaboration has resulted in about hundred gravitational-wave triggers including the binary neutron star merger GW190425. However, none o…
High-accuracy simulations of highly spinning binary neutron star systems
Reetika Dudi, Tim Dietrich, Alireza Rashti +3
With an increasing number of expected gravitational-wave detections of binary neutron star mergers, it is essential that gravitational-wave models employed for the analysis of obse…
Tests of General Relativity with Binary Black Holes from the second LIGO-Virgo Gravitational-Wave Transient Catalog
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1344
Gravitational waves enable tests of general relativity in the highly dynamical and strong-field regime. Using events detected by LIGO-Virgo up to 1 October 2019, we evaluate the co…
Gravitational waves and mass ejecta from binary neutron star mergers: Effect of the spin orientation
Swami Vivekanandji Chaurasia, Tim Dietrich, Maximiliano Ujevic +5
We continue our study of the binary neutron star parameter space by investigating the effect of the spin orientation on the dynamics, gravitational wave emission, and mass ejection…
Distinguishing high-mass binary neutron stars from binary black holes with second- and third-generation gravitational wave observatories
An Chen, Nathan K. Johnson-McDaniel, Tim Dietrich +1
(Abridged) While the gravitational-wave (GW) signal GW170817 was accompanied by a variety of electromagnetic (EM) counterparts, sufficiently high-mass binary neutron star (BNS) mer…
Constructing Binary Neutron Star Initial Data with High Spins, High Compactness, and High Mass-Ratios
Wolfgang Tichy, Alireza Rashti, Tim Dietrich +2
The construction of accurate and consistent initial data for various binary parameters is a critical ingredient for numerical relativity simulations of the compact binary coalescen…
Improving the NRTidal model for binary neutron star systems
Tim Dietrich, Anuradha Samajdar, Sebastian Khan +3
Accurate and fast gravitational waveform (GW) models are essential to extract information about the properties of compact binary systems that generate GWs. Building on previous wor…
Quasi-5.5PN TaylorF2 approximant for compact binaries: point-mass phasing and impact on the tidal polarizability inference
Francesco Messina, Reetika Dudi, Alessandro Nagar +1
We derive a point-mass (nonspinning) frequency-domain TaylorF2 phasing approximant at quasi-5.5 post-Newtonian (PN) accuracy for the gravitational wave from coalescing compact bina…
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…
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…
Matter imprints in waveform models for neutron star binaries: tidal and self-spin effects
Tim Dietrich, Sebastian Khan, Reetika Dudi +16
The combined observation of gravitational and electromagnetic waves from the coalescence of two neutron stars marks the beginning of multi-messenger astronomy with gravitational wa…
