Particle cosmology

TL;DR

This paper reviews the current standard cosmological model, focusing on the origin of cosmic perturbations, dark matter, and dark energy, highlighting recent developments in understanding the universe's large-scale structure.

Contribution

It provides a comprehensive overview of the hot Big Bang, inflation, and the origins of cosmic structures, emphasizing recent insights into dark matter and dark energy.

Findings

Cosmic microwave background anisotropies explained by primordial perturbations

Large scale structure linked to inflationary fluctuations

Dark matter and dark energy remain key puzzles in cosmology

Abstract

In these lectures the present status of the so-called standard cosmological model, based on the hot Big Bang theory and the inflationary paradigm is reviewed. Special emphasis is given to the origin of the cosmological perturbations we see today under the form of the cosmic microwave background anisotropies and the large scale structure and to the dark matter and dark energy puzzles.
