Comparison of 4.5PN and 2SF gravitational energy fluxes from quasicircular compact binaries
Niels Warburton, Barry Wardell, David Trestini +6
Recent years have seen significant advances in models of gravitational waveforms emitted by quasicircular compact binaries in two regimes: the weak-field, post-Newtonian regime, in…
Worldtube puncture scheme for first- and second-order self-force calculations in the Fourier domain
Jeremy Miller, Benjamin Leather, Adam Pound +1
Second-order gravitational self-force theory has recently led to the breakthrough calculation of ``first post-adiabatic'' (1PA) compact-binary waveforms [Phys. Rev. Lett. 130, 2414…
Accuracy Requirements: Assessing the Importance of First Post-Adiabatic Terms for Small-Mass-Ratio Binaries
Ollie Burke, Gabriel Andres Piovano, Niels Warburton +7
We investigate the impact of post-adiabatic (1PA) terms on parameter estimation for extreme and intermediate mass-ratio inspirals using state-of-the-art waveform models. Our analys…
Enhancing the SEOBNRv5 effective-one-body waveform model with second-order gravitational self-force fluxes
Maarten van de Meent, Alessandra Buonanno, Deyan P. Mihaylov +7
We leverage recent breakthrough calculations using second-order gravitational self-force (2GSF) theory to improve both the gravitational-mode amplitudes and radiation-reaction forc…
Gravastar-like black hole solutions in -theory
M. Selch, J. Miller, M. A. Zubkov
We present a stationary spherically symmetric solution of the Einstein equations, with a source generated by a scalar field of -theory. In this theory Riemannian gravity, as des…
Comparing second-order gravitational self-force and effective one body waveforms from inspiralling, quasi-circular and nonspinning black hole binaries II: the large-mass-ratio case
Angelica Albertini, Alessandro Nagar, Adam Pound +4
We compare recently computed waveforms from second-order gravitational self-force (GSF) theory to those generated by a new, GSF-informed, effective one body (EOB) waveform model fo…
Comparing second-order gravitational self-force, numerical relativity and effective one body waveforms from inspiralling, quasi-circular and nonspinning black hole binaries
Angelica Albertini, Alessandro Nagar, Adam Pound +4
We present the first systematic comparison between gravitational waveforms emitted by inspiralling, quasi-circular and nonspinning black hole binaries computed with three different…
Gravitational waveforms for compact binaries from second-order self-force theory
Barry Wardell, Adam Pound, Niels Warburton +3
We produce gravitational waveforms for nonspinning compact binaries undergoing a quasicircular inspiral. Our approach is based on a two-timescale expansion of the Einstein equation…
Gravitational-wave energy flux for compact binaries through second order in the mass ratio
Niels Warburton, Adam Pound, Barry Wardell +2
Within the framework of self-force theory, we compute the gravitational-wave energy flux through second order in the mass ratio for compact binaries in quasicircular orbits. Our re…
Two-timescale evolution of extreme-mass-ratio inspirals: waveform generation scheme for quasicircular orbits in Schwarzschild spacetime
Jeremy Miller, Adam Pound
Extreme-mass-ratio inspirals, in which a stellar-mass compact object spirals into a supermassive black hole in a galactic core, are expected to be key sources for LISA. Modelling t…
Second-order self-force calculation of the gravitational binding energy in compact binaries
Adam Pound, Barry Wardell, Niels Warburton +1
Self-force theory is the leading method of modeling extreme-mass-ratio inspirals (EMRIs), key sources for the gravitational-wave detector LISA. It is well known that for an accurat…
Second-order perturbation theory: the problem of infinite mode coupling
Jeremy Miller, Barry Wardell, Adam Pound
Second-order self-force computations, which will be essential in modeling extreme-mass-ratio inspirals, involve two major new difficulties that were not present at first order. One…
A practical, covariant puncture for second-order self-force calculations
Adam Pound, Jeremy Miller
Accurately modeling an extreme-mass-ratio inspiral requires knowledge of the second-order gravitational self-force on the inspiraling small object. Recently, numerical puncture sch…
