On the accuracy and precision of numerical waveforms: Effect of waveform extraction methodology
Tony Chu, Heather Fong, Prayush Kumar +6
We present a new set of 95 numerical relativity simulations of non-precessing binary black holes (BBHs). The simulations sample comprehensively both black-hole spins up to spin mag…
Science with the space-based interferometer eLISA. I: Supermassive black hole binaries
Antoine Klein, Enrico Barausse, Alberto Sesana +8
We compare the science capabilities of different eLISA mission designs, including four-link (two-arm) and six-link (three-arm) configurations with different arm lengths, low-freque…
Formulation of discontinuous Galerkin methods for relativistic astrophysics
Saul A. Teukolsky
The DG algorithm is a powerful method for solving pdes, especially for evolution equations in conservation form. Since the algorithm involves integration over volume elements, it i…
Challenging the Presence of Scalar Charge and Dipolar Radiation in Binary Pulsars
Kent Yagi, Leo C. Stein, Nicolas Yunes
Corrections to general relativity that introduce long-ranged scalar fields which are non-minimally coupled to curvature typically predict that neutron stars possess a non-trivial s…
Gravitational waveforms for neutron star binaries from binary black hole simulations
Kevin Barkett, Mark A. Scheel, Roland Haas +9
Gravitational waves from binary neutron star (BNS) and black hole/neutron star (BHNS) inspirals are primary sources for detection by the Advanced Laser Interferometer Gravitational…
Transformations of asymptotic gravitational-wave data
Michael Boyle
Gravitational-wave data is gauge dependent. While we can restrict the class of gauges in which such data may be expressed, there will still be an infinite-dimensional group of tran…
Binary Neutron Stars with Arbitrary Spins in Numerical Relativity
Nick Tacik, Francois Foucart, Harald P. Pfeiffer +8
We present a code to construct initial data for binary neutron star systems in which the stars are rotating. Our code, based on a formalism developed by Tichy, allows for arbitrary…
Improvements to the construction of binary black hole initial data
Serguei Ossokine, Francois Foucart, Harald P. Pfeiffer +2
Construction of binary black hole initial data is a prerequisite for numerical evolutions of binary black holes. This paper reports improvements to the binary black hole initial da…
Octupolar invariants for compact binaries on quasi-circular orbits
Patrick Nolan, Chris Kavanagh, Sam R Dolan +3
We extend the gravitational self-force methodology to identify and compute new tidal invariants for a compact body of mass on a quasi-circular orbit about a black hole o…
Applying the effective-source approach to frequency-domain self-force calculations: Lorenz-gauge gravitational perturbations
Barry Wardell, Niels Warburton
With a view to developing a formalism that will be applicable at second perturbative order, we devise a new practical scheme for computing the gravitational self-force experienced…
Static Self-Forces in a Five-Dimensional Black Hole Spacetime
Peter Taylor, Éanna É. Flanagan
We obtain the electric field and scalar field for a static point charge in closed form in the 5D Schwarzschild-Tangherlini black hole spacetime. We then compute the static self-for…
Is motion under the conservative self-force in black hole spacetimes an integrable Hamiltonian system?
Justin Vines, Éanna É. Flanagan
A point-like object moving in a background black hole spacetime experiences a gravitational self-force which can be expressed as a local function of the object's instantaneous posi…
Analytical high-order post-Newtonian expansions for extreme mass ratio binaries
Chris Kavanagh, Adrian C. Ottewill, Barry Wardell
We present analytic computations of gauge invariant quantities for a point mass in a circular orbit around a Schwarzschild black hole, giving results up to 15.5 post-Newtonian orde…
Numerical relativity reaching into post-Newtonian territory: a compact-object binary simulation spanning 350 gravitational-wave cycles
Bela Szilagyi, Jonathan Blackman, Alessandra Buonanno +6
We present the first numerical-relativity simulation of a compact-object binary whose gravitational waveform is long enough to cover the entire frequency band of advanced gravitati…
Comparing Post-Newtonian and Numerical-Relativity Precession Dynamics
Serguei Ossokine, Michael Boyle, Lawrence E. Kidder +3
Binary black-hole systems are expected to be important sources of gravitational waves for upcoming gravitational-wave detectors. If the spins are not colinear with each other or wi…
Fast and accurate prediction of numerical relativity waveforms from binary black hole coalescences using surrogate models
Jonathan Blackman, Scott E. Field, Chad R. Galley +4
Simulating a binary black hole (BBH) coalescence by solving Einstein's equations is computationally expensive, requiring days to months of supercomputing time. Using reduced order…
Self-force: Computational Strategies
Barry Wardell
Building on substantial foundational progress in understanding the effect of a small body's self-field on its own motion, the past 15 years has seen the emergence of several strate…
Testing General Relativity with Present and Future Astrophysical Observations
Emanuele Berti, Enrico Barausse, Vitor Cardoso +50
One century after its formulation, Einstein's general relativity has made remarkable predictions and turned out to be compatible with all experimental tests. Most of these tests pr…
