Classical double copy at null infinity

Abstract We give two double copy prescriptions which construct asymptotically flat solutions in gravity from gauge fields. The first prescription applies to radiative fields, are non-linear vacuum determined by characteristic data at null infinity. For any such fields (linear or non-linear), the of a metric, dilaton and axion is constructed simple ‘squaring’ procedure, giving classical level radiation demonstrate procedure with several examples where can be explicitly integrated; for linear this also sheds light on twistorial description Weyl copy. Our second all their asymptotic equations motion: we map between solution Maxwell Einstein This extends charges duals, preserves soft hard sectors theory gravity, related usual notion scattering amplitudes.
