 Title: Effect of Non-Gaussianity from Multi-Field Models on the Large Scale Structure
 Key Words: Non-Gaussianity, Large Scale Structure, N-body simulations
 Abstract: We investigate the signature of primordial non-Gaussianity generated from multi-field models on large scale structure using N-body simulations. We examine how the gravitational evolution of perturbations changes by an addition of small amount of highly non-Gaussian field to the dominant adiabatic Gaussian field. We systematically performed simulations over various models of the non-Gaussian field for its type of non-Gaussianity, adiabaticity, and correlation to the Gaussian field.  We found that scale-dependence of bias and stochasticity of clustering of the simulated dark matter haloes to that of matter density field are common natures for a wide range of multi-field models. We also discuss the detectability and feasibility of distinction among different models from future observations.
