# Numerical Simulations in Cosmology I: Methods

@article{Klypin2000NumericalSI, title={Numerical Simulations in Cosmology I: Methods}, author={Anatoly Klypin}, journal={arXiv: Astrophysics}, year={2000} }

This lecture gives a short introduction to different methods used in cosmology. The focus is on major features of N-body simulations: equations, main numerical techniques, effects of resolution, and methods of halo identification.

### Cosmology and stellar equilibrium using Newtonian hydrodynamics with general relativistic pressure

- Physics
- 2016

We revisit the analysis made by Hwang and Noh [JCAP 1310 (2013)] aiming the construction of a Newtonian set of equations incorporating pressure effects typical of the General Relativity theory. We…

### Galaxy and structure formation in dynamical and coupled dark energy

- Physics
- 2015

In this thesis I study the effects of different Dark Energy models on galaxy formation via numerical simulations. I investigate systems around and be- low Milky-Way masses and describe the effects of…

### A lower bound on the mass of dark matter particles

- Physics
- 2009

We discuss the bounds on the mass of Dark Matter (DM) particles, coming from the analysis of DM phase-space distribution in dwarf spheroidal galaxies (dSphs). After reviewing the existing approaches,…

### Lyman-alpha constraints on warm and on warm-plus-cold dark matter models

- Physics
- 2009

We revisit Lyman-alpha bounds on the dark matter mass in Lambda Warm Dark Matter (Lambda-WDM) models, and derive new bounds in the case of mixed Cold plus Warm models (Lambda-CWDM), using a set up…

### Mark Correlations: Relating Physical Properties to Spatial Distributions

- Physics
- 2002

Mark correlations provide a systematic approach to look at objects both distributed in space and bearing intrinsic information, for instance on physical properties. The interplay of the objects'…

### How can computer simulations produce new knowledge?

- Philosophy
- 2012

It is often claimed that scientists can obtain new knowledge about nature by running computer simulations. How is this possible? I answer this question by arguing that computer simulations are…
