How accurate is Spectral Einstein Code (SpEC)? And what limits its accuracy?
Himanshu Chaudhary, Mark A. Scheel, Robert Owen +4
The improved sensitivity of upcoming gravitational-wave detectors will require correspondingly more accurate binary black hole (BBH) simulations. Given the high cost of such simula…
A catalog of long, eccentric and precessing binary black hole simulations from ICTS-TIFR
Vaishak Prasad, Prayush Kumar, Michael Boyle +3
We present a catalogue of 31 binary black hole simulations performed with the Spectral Einstein Code (SpEC) on the Sonic cluster at ICTS-TIFR, Bengaluru between August 2023 and Dec…
Quadratic Gravitational-Wave Scattering by Kerr Black Holes
Lennox S. Keeble, Hengrui Zhu, Lawrence E. Kidder +2
Second-order black-hole perturbation theory will be an important component of precision gravitational-wave modeling and tests of strong-field gravity with next-generation detectors…
Enabling gravitational-wave astronomy with spin-precessing black holes on generic orbits
Aldo Gamboa, Lorenzo Pompili, Alessandra Buonanno +7
Binary black holes (BBHs) formed in dense stellar environments or in hierarchical triples can coalesce on eccentric orbits and carry spins of arbitrary orientation, leaving distinc…
High-accuracy drivers to simulate black hole binaries beyond general relativity with the fixing-the-equations approach
Guillermo Lara, Harald P. Pfeiffer, Nils Deppe +9
We implement the "fixing-the-equations" approach [Phys.Rev.D 96 (2017) 8, 084043] in spectre, an NR code using a pseudo-spectral discontinuous Galerkin scheme, to produce long and…
Towards long and accurate numerical relativity waveforms of binary black holes beyond general relativity
Guillermo Lara, Harald P. Pfeiffer, Nils Deppe +9
Numerical relativity (NR) simulations of compact binaries in theories beyond general relativity (GR) will be pivotal for the continued development of future tests of gravity with g…
Impact of neutrino-electron scattering and an improved treatment of pair processes on binary neutron star mergers
Francois Foucart, Samantha Rath, Rowan Davidson +5
Multimessenger observations of neutron star mergers are unique opportunities to constrain the properties of dense matter and the production site of heavy nuclei. To leverage these…
Assessing the Relative Importance of Neutrino Matter Interaction Channels in Post-Merger Remnant of Binary Neutron Stars
Samantha Rath, Francois Foucart, Lawrence E. Kidder +2
Neutron star mergers are amongst the most promising sources for the joint detection of gravitational waves and electromagnetic signals. They are also potential sites for the produc…
Accurate waveforms for generic planar-orbit binary black holes: The multipolar effective-one-body model SEOBNRv6EHM
Aldo Gamboa, Alessandra Buonanno, Lorenzo Pompili +8
Accurate and computationally efficient waveform models are required to infer the parameters of compact binaries from their gravitational wave (GW) emission. Among these parameters,…
Merger remnant and eccentricity dynamics surrogates for eccentric nonspinning black hole binaries
Adhrit Ravichandran, Peter James Nee, Keefe Mitman +22
Accurate models of merger remnants are increasingly important for gravitational-wave science, including precision tests of gravity with ringdown, inference of black-hole population…
Including higher-order modes in a quadrupolar eccentric numerical relativity surrogate using universal eccentric modulation functions
Tousif Islam, Adhrit Ravichandran, Peter James Nee +15
\texttt{gwNRHME} is a framework that converts multi-modal (i.e., containing several spherical harmonic modes) quasi-circular waveforms into their eccentric counterparts, provided t…
LISA science ground segment conventions
Quentin Baghi, Stanislas Babak, Leor Barack +22
This document sets out the conventions used for data simulations, waveforms, and analysis pipelines within the Distributed Data Processing Centre (DDPC) of the Laser Interferometer…
