In this paper, the equation of motion of a small, compact body in an external vacuum spacetime through second order in the body's mass was derived using a rigorous method of matched asymptotic expansions.
Abstract
Using a rigorous method of matched asymptotic expansions, I derive the equation of motion of a small, compact body in an external vacuum spacetime through second order in the body's mass (neglecting effects of internal structure). The motion is found to be geodesic in a certain locally defined regular geometry satisfying Einstein's equation at second order. I outline a method of numerically obtaining both the metric of that regular geometry and the complete second-order metric perturbation produced by the body.

A Relativist's Toolkit, The Mathematics of Black-Hole Mechanics

TL;DR: In this article, the authors present a toolkit for general relativity with a focus on the application of general relativity to black hole spacetimes, including a discussion of isolated and dynamical horizons, which Ashtekar and coworkers have done so much to develop recently.

Energetics and scattering of gravitational two-body systems at fourth post-Minkowskian order

TL;DR: In this article , the authors compared the accuracy of the 4PM-expanded Hamiltonian with numerical-relativity (NR) simulations for the circular-orbit binding energy and for the scattering angle.

Classical theory of radiating electrons

TL;DR: In this article, the authors argue that the Lorentz model has reached the limit of its usefulness and must be abandoned before we can make further progress in the field of physics.

Gravitational field of a particle falling in a schwarzschild geometry analyzed in tensor harmonics

TL;DR: In this article, the authors considered the problem of a small particle falling in a Schwarzschild background ("black hole") and examined its spectrum in the high-frequency limit, in terms of the traceless transverse tensor harmonics called electric and magnetic by Mathews.
