Analytic self-force calculations in the post-Newtonian regime: eccentric orbits on a Schwarzschild background

Seth Hopper, Chris Kavanagh, Adrian C. Ottewill

We present a method for solving the first-order field equations in a post-Newtonian (PN) expansion. Our calculations generalize work of Bini and Damour and subsequently Kavanagh et…

Numerical computation of the EOB potential q using self-force results

Sarp Akcay, Maarten van de Meent

The effective-one-body theory (EOB) describes the conservative dynamics of compact binary systems in terms of an effective Hamiltonian approach. The Hamiltonian for moderately ecce…

Eccentric-orbit EMRI gravitational wave energy fluxes to 7PN order

Erik Forseth, Charles R. Evans, Seth Hopper

We present new results through 7PN order on the energy flux from eccentric extreme-mass-ratio binaries. The black hole perturbation calculations are made at very high accuracy (200…

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…

High-order Tail in Schwarzschild Space-time

Marc Casals, Adrian C. Ottewill

We present an analysis of the behaviour at late-times of linear field perturbations of a Schwarzschild black hole space-time. In particular, we give explicit analytic expressions f…

Geometric properties of a 2-D space-time arising in 4-D black hole physics

Marc Casals, Brien C. Nolan

The Schwarzschild exterior space-time is conformally related to a direct product space-time, , where is a two-dimensional space-time. This…

Equations of Motion of Schwarzschild, Reissner-Nordstrom and Kerr Particles

Peter A. Hogan

A technique for extracting from the appropriate field equations the relativistic motion of Schwarzschild, Reissner-Nordstrom and Kerr particles moving in external fields is motivat…

Vacuum polarization on the brane

Cormac Breen, Matthew Hewitt, Adrian C. Ottewill +1

We compute the renormalized expectation value of the square of a massless, conformally coupled, quantum scalar field on the brane of a higher-dimensional black hole. Working in the…

Fast spectral source integration in black hole perturbation calculations

Seth Hopper, Erik Forseth, Thomas Osburn +1

This paper presents a new technique for achieving spectral accuracy and fast computational performance in a class of black hole perturbation and gravitational self-force calculatio…

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…

Comparison Between Self-Force and Post-Newtonian Dynamics: Beyond Circular Orbits

Sarp Akcay, Alexandre Le Tiec, Leor Barack +2

The gravitational self-force (GSF) and post-Newtonian (PN) schemes are complementary approximation methods for modelling the dynamics of compact binary systems. Comparison of their…

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…

Colliding Impulsive Gravitational Waves and a Cosmological Constant

C. Barrabès, P. A. Hogan

We present a space--time model of the collision of two homogeneous, plane impulsive gravitational waves (each having a delta function profile) propagating in a vacuum before collis…
