Cosmological N-body simulations have become an essential tool for studying formation of large scale structure. These simulations are computationally challenging even though the available computing power gets better every year. A number of efficient algorithms have been developed to run large simulations with better dynamic range and resolution. We discuss key algorithms in this review, focusing on techniques used and their efficacy. N-body simulations solve a model that is an approximation of… Expand
Effects of the size of cosmological N-body simulations on physical quantities – III. Skewness
N-body simulations are an important tool in the study of formation of large-scale structures. Much of the progress in understanding the physics of galaxy clustering and comparison with observationsExpand
The Adaptive TreePM: an adaptive resolution code for cosmological N‐body simulations
Cosmological N-body simulations are used for a variety of applications. Indeed progress in the study of large-scale structures and galaxy formation would have been very limited without this tool. ForExpand
Physical Models of Galaxy Formation in a Cosmological Framework
Modeling galaxy formation in a cosmological context presents one of the greatest challenges in astrophysics today due to the vast range of scales and numerous physical processes involved. Here weExpand
A new gravitational N-body simulation algorithm for investigation of cosmological chaotic advection
Recently alternative approaches in cosmology seeks to explain the nature of dark matter as a direct result of the non-linear spacetime curvature due to different types of deformation potentials. InExpand
Towards quantitative control on discreteness error in the non-linear regime of cosmological N-body simulations
The effects of discreteness arising from the use of the N-body method on the accuracy of simulations of cosmological structure formation are not currently well understood. In the first part of thisExpand
A new framework for numerical simulations of structure formation
In the absence of a full analytical treatment of nonlinear structure formation in the universe, numerical simulations provide the critical link between the properties of the underlying model and theExpand
Spatial description of large scale structure and reionisation
This thesis is the result of a PhD project that tried to investigate and find new descriptions of entities arising in large scale structure based upon their spatial configuration. For this we analyseExpand

The standard paradigm of cosmology assumes General Relativity (GR) is a valid theory for gravity at scales in which it has not been properly tested. Developing novel tests of GR and its alternativesExpand
Particle-based sampling of N-body simulations
This paper introduces a novel approach for sampling the orbits of an N-body simulation. The gist of the method is to exploit individual phase-space coordinates acquired during integration of theExpand
Yukawa vs. Newton: gravitational forces in a cubic cosmological simulation box
We study the behaviour of Yukawa and Newtonian gravitational forces in a cubic box with fully periodic boundaries commonly encountered in N-body simulations of the structure formation. Placing aExpand
