Motivated by conceptual problems in quantum theories of gravity, the gravitational eikonal
approach, inspired by its electromagnetic predecessor, has been successfully applied to the …

The post-Minkowskian expansion of Einstein's general theory of relativity has received much
attention in recent years due to the possibility of harnessing the computational power of …

We complete the calculation of conservative two-body scattering dynamics at fourth post-
Minkowskian order, ie, O (G 4) and all orders in velocity, including radiative contributions …

Using scattering amplitudes, we obtain the potential contributions to conservative binary
dynamics in general relativity at fourth post-Minkowskian order O (G 4). As in previous lower …

Using the N= 1 supersymmetric, spinning worldline quantum field theory formalism, we
compute the conservative spin-orbit part of the momentum impulse Δ pi μ, spin kick Δ S i μ …

A bstract Using a heavy-mass effective field theory (HEFT), we study gravitational-wave
emission in the scattering of two spinless black holes or neutron stars of arbitrary masses at …

We compute the conservative dynamics of nonspinning binaries at fourth post-Minkowskian
order in the large-eccentricity limit, including both potential and radiation-reaction tail effects …

A bstract We propose a method to compute the scattering angle for classical black hole
scattering directly from two massive particle irreducible diagrams in a heavy-mass effective …

A bstract Using\(\mathcal {N}\)= 8 supergravity as a theoretical laboratory, we extract the
3PM gravitational eikonal for two colliding massive scalars from the classical limit of the …

A bstract We compute classical gravitational observables for the scattering of two spinless
black holes in general relativity and\(\mathcal {N}\)= 8 supergravity in the formalism of …
