We derive the total radiated spacetime momentum as well as the associated energy flux. The latter can be
used to compute gravitational-wave observables for generic (un)bound orbits. We employ the (“in-in”)
Schwinger-Keldysh worldline effective field theory framework in combination with modern “multiloop”
integration techniques from collider physics. The complete results are in agreement with various partial
calculations in the post-Minkowskian and post-Newtonian expansion.
