Query: Non-gaussian Features of Linear Cosmic String Models   We investigate the non-gaussian properties of cosmic-string-seeded linear
density perturbations with cold and hot dark matter backgrounds, using
high-resolution numerical simulations. We compute the one-point probability
density function of the resulting density field, its skewness, kurtosis, and
genus curves for different smoothing scales. A semi-analytic model is then
invoked to provide a physical interpretation of our results. We conclude that
on scales smaller than $1.5{(\Omega h^2)}^{-1}$Mpc, perturbations seeded by
cosmic strings are very non-gaussian. These scales may still be in a linear or
mildly non-linear regime in an open or $\Lambda$-universe with $\Gamma=\Omega h
\lsim 0.2$.
