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

We obtain the total impulse in the scattering of nonspinning binaries in general relativity at
fourth post-Minkowskian order, ie, O (G 4), including linear, nonlinear, and hereditary …

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

We compute the radiation reacted momentum impulse Δ pi μ, spin kick Δ S i μ, and
scattering angle θ between two scattered spinning massive bodies (black holes or neutron …

Using the spinning worldline quantum field theory formalism we calculate the quadratic-in-
spin momentum impulse Δ pi μ and spin kick Δ ai μ from a scattering of two arbitrarily …

We calculate the scattering amplitude of two rotating objects with the linear-in-curvature spin-
induced multipoles of Kerr black holes at O (G 2) and all orders in the spins of both objects …

We show how to compute classical wave observables using quantum scattering amplitudes.
We discuss observables both with incoming and with outgoing waves. The required …

A bstract By combining the KMOC-formalism with the exponential representation of the
scattering matrix we show that the two-body scattering angle is given by the corresponding …
