Query: Imprint of primordial non-Gaussianity on dark matter halo profiles   We study the impact of primordial non-Gaussianity on the density profile of
dark matter halos by using the semi-analytical model introduced recently by
Dalal {\it et al.} which relates the peaks of the initial linear density field
to the final density profile of dark matter halos. Models with primordial
non-Gaussianity typically produce an initial density field that differs from
that produced in Gaussian models. We use the path-integral formulation of
excursion set theory to calculate the non-Gaussian corrections to the peak
profile and derive the statistics of the peaks of non-Gaussian density field.
In the context of the semi-analytic model for halo profiles, currently allowed
values for primordial non-Gaussianity would increase the shapes of the inner
dark matter profiles, but only at the sub-percent level except in the very
innermost regions.
