Query: Classical Gravitational Bremsstrahlung from a Worldline Quantum Field
  Theory   Using the recently established formalism of a worldline quantum field theory
(WQFT) description of the classical scattering of two spinless black holes, we
compute the far-field time-domain waveform of the gravitational waves produced
in the encounter at leading order in the post-Minkowskian (weak field, but
generic velocity) expansion. We reproduce previous results of Kovacs and Thorne
in a highly economic way. Then using the waveform we extract the leading-order
total radiated angular momentum and energy (including differential results).
Our work may enable crucial improvements of gravitational-wave predictions in
the regime of large relative velocities.
