This paper describes the generation of Gaussian random fields with multiple levels of resolution. We present the theory of adaptive mesh refinement of Gaussian random fields followed by the implementation and testing of a computer code package performing this refinement called "GRAFIC2." This package is available to the computational cosmology community at or by e-mail from the author. 

Initial Conditions For Large Cosmological Simulations

This technical paper describes a software package that was designed to produce initial conditions for large cosmological simulations in the context of the Horizon collaboration. These tools

On fast generation of cosmological random fields

The statistical translation invariance of cosmological random fields is broken by a finite survey boundary, correlating the observable Fourier modes. Standard methods for generating Gaussian fields

Structure, Kinematics and Evolution of Elliptical Galaxies from Hydrodynamical Simulations

Introduction This work presents an original approach to the study of the formation and evolution of elliptical galaxies in a cosmological context. The first section of this introduction is concerned

Initial Conditions to Cosmological N-Body Simulations, or, How to Run an Ensemble of Simulations

The conventional method of generating initial conditions for cosmological N-body simulations introduces a significant error in the real-space statistical properties of the particles. More

Resolution convergence in cosmological hydrodynamical simulations using adaptive mesh refinement

We have explored the evolution of gas distributions from cosmological simulations carried out using the RAMSES adaptive mesh refinement (AMR) code, to explore the effects of resolution on

Numerical investigation of lens models with substructures using the perturbative method

We present a statistical study of the effects induced by substructures on the deflection potential of dark matter haloes in the strong lensing regime. This investigation is based on the pertubative

Efficient Simulation of Stationary Multivariate Gaussian Random Fields with Given Cross-Covariance

A new approach to simulate any stationary multivariate Gaussian random field whose cross-covariances are predefined continuous and integrable functions, developed to support simulation algorithms for mineral microstructures in geoscience.

Density field in extended Lagrangian perturbation theory

We analyze the performance of a perturbation theory for nonlinear cosmological dynamics, based on the Lagrangian description of hydrodynamics. In our previous paper, we solved the hydrodynamic

Setting the stage: structures from Gaussian random fields

We study structure formation in a set of cosmological simulations to uncover the scales in the initial density field that gave rise to the formation of present-day structures. Our simulations share a

We study the impact of setting initial conditions in numerical simulations using the standard procedure based on the Zel'dovich approximation (ZA). As it is well known from the perturbation theory,



Constrained realizations of Gaussian fields : a simple algorithm

A straightforward method for the construction of constrained realizations of Gaussian fields is presented, based on a simple construction of this residual field, which is then added to the analytically calculated mean field.

Can dissipationless N-body simulations be used to reliably determine the structural and substructure properties of dark matter halos? A large simulation of a galaxy cluster in a cold dark matter

Generation of Correlated and Constrained Gaussian Stochastic Processes for N-Body Simulations

A novel method of generating initial conditions for cosmolo gical simulations based on the filtering of white noise and it is shown that instances of constrained GSPs may be obtained from instances of unconstrained processes by another simple filtering proces.
