  "abstract": "We characterize the wave front set $WF^P_\\ast(u)$ with respect to the iterates of a linear partial differential operator with constant coefficients of a classical distribution $u\\in{\\mathcal D}'(\\Omega)$, $\\Omega$ an open subset in ${\\mathbb R}^n$. We use recent Paley-Wiener theorems for generalized ultradifferentiable classes in the sense of Braun, Meise and Taylor. We also give several examples and applications to the regularity of operators with variable coefficients and constant strength. Finally, we construct a distribution with prescribed wave front set of this type.",
