Effective-one-body (EOB) waveforms employed by the LIGO-Virgo-KAGRA Collaboration
have primarily been developed by resumming the post-Newtonian expansion of the …

We compute the purely local-in-time (scale-free and logarithm-free) part of the conservative
dynamics of gravitationally interacting two-body systems at the fourth post-Minkowskian …

Effective-one-body (EOB) models are based on analytical building blocks that,
mathematically, are truncated Taylor series with logarithms. These functions are usually …

A bstract Worldline quantum field theory (WQFT) has proven itself a powerful tool for
classical two-body scattering calculations in general relativity. In this paper we develop a …

Computation of spin-resummed observables in post-Minkowskian dynamics typically involve
evaluation of Feynman integrals deformed by an exponential factor, where the exponent is a …

The measurement of orbital eccentricity in gravitational-wave (GW) signals will provide
unique insights into the astrophysical origin of binary systems, while ignoring eccentricity in …

A bstract Employing techniques from scattering amplitudes and effective field theory, we
model the dynamics of hierarchical triples, which are three-body systems composed of two …

In the last decade, the first law of binary black hole mechanics played an important unifying
role in the gravitational two-body problem. More recently, binary black hole scattering and …

Geodesic scattering of a test particle off a Schwarzschild black hole can be parametrized by
the speed-at-infinity v and the impact parameter b, with a “separatrix,” b= bc (v), marking the …

We study observables in the scattering of classical, spinning objects using the KMOC
formalism. In particular, we derive formulas to higher order in spin and one loop $\mathcal …
