Query: Momentum dependence of the bispectrum in two-field inflation   We examine the momentum dependence of the bispectrum of two-field
inflationary models within the long-wavelength formalism. We determine the
sources of scale dependence in the expression for the parameter of
non-Gaussianity fNL and study two types of variation of the momentum triangle:
changing its size and changing its shape. We introduce two spectral indices
that quantify the possible types of momentum dependence of the local type fNL
and illustrate our results with examples.
