      abstract     = {In this paper we study the multipole expansion of the
                      long-wavelength effective action for radiative sources in
                      (d+1) spacetime dimensions. We present detailed expressions
                      for the multipole moments for the case of scalar-,
                      electromagnetic-, and (linearized) gravitational-wave
                      emission. For electromagnetism and gravity, we derive
                      expressions for the odd-parity, magnetic-type moments as
                      SO(d) duals of the ones traditionally used in the
                      literature. The d-dimensional case features a novel set of
                      “Weyl-type” moments, coupling to the spatial part of the
                      Weyl tensor, which are absent in three dimensions. Agreement
                      is found in the overlap with previous known results, notably
                      in the d→3 limit. Because of its reliance on dimensional
                      regularization, the results presented here play a crucial
                      role for the further development of the effective field
                      theory approach to gravitational dynamics, and in particular
                      for the computation of the gravitational-wave flux, starting
                      at the third post-Newtonian order.},
