- Contents
Introduction to the general relativity and the Einstein equations for the gravitational field. The cosmological problem: the Friedmann-Lemaitre equations, cosmological models and the Big-Bang theory. Cosmological paramenters: astrophysical and astro-particle experimental observations for their measurement.- Reference texts
Weinberg, Gravitation and Cosmology Bergstrom-Goobar, Cosmology and Astroparticle Physics Handouts and notes are made available to the students along the teaching period on the Unistudium online platform.- Educational objectives
The main objective of this course is to give an up-to-date overview of the most significant models used to describe the evolution of the universe as well as to give a flavour of the current challenges and open issues in the field. Connections between the cosmological problem and fundamental particle physics are evidentiated both from the theoretical and the experimental point of view.- Prerequisites
A basic knowledge of special relativity and particle physics are highly desirable in order to fully understand and to know how to tackle the course.- Teaching methods
Lectures of 2-3 hours.- Other information
- Even if not strictly mandatory, attendance to the lectures is highly recommended.
- Learning verification modality
The exam consists of a 45'-60' interview with question on the different topics addressed in the lectures.- Extended program
Summary of special relativity. Energy-Momentum tensor definition. Introduction to general relativity, Robertson-Walker metric, Friedmann-Lemaitre equations, energy, radiation and matter balance in the universe. Cosmologic models. Cosmography: definition of redshift and deceleration parameter of the RW metric, astrophysical observation of the geometrical properties of the universe. The Big-Bang model: the phases of the primordial universe evolution. Introduction to inflation, nucleosynthesis, recombination. The rise of the background cosmic radiation.
