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 apply a formulation of Einstein's general relativity with only cubic interactions for deriving
the metric of a Schwarzschild black hole to all orders in perturbation theory. This cubic …

A bstract Using universal predictions provided by classical soft theorems, we revisit the
energy emission spectrum for gravitational scatterings of compact objects in the low …

Using the multipolar post-Minkowskian formalism, we compute the frequency-domain
waveform generated by the gravitational scattering of two nonspinning bodies at the fourth …

A bstract The dynamics of the leading self-force (0SF) order, corresponding to the geodesic
motion of a light body in the exact background of a heavy body, are explicitly derived for the …

We review the description of classical gravitational scatterings of two compact objects by
means of the eikonal framework. This encodes via scattering amplitudes both the motion of …

A bstract We extend the Veneziano and Shapiro-Virasoro amplitudes to four arbitrarily
excited states in bosonic string theory. We use the formalism of coherent string states based …

In this paper we present an approach to compute analytical post-Minkowskian corrections to
unbound two-body scattering in the self-force formalism. Our method relies on a further low …

A bstract Tree-level gravitational amplitudes satisfy an infinite hierarchy of soft factorization
theorems. The existence of these theorems has been recently linked with the existence of an …

Emitted radiation and absorption effects in black hole dynamics lead to inelastic scattering
amplitudes. In this paper, we study how these effects introduce an inelasticity function to the …
