Prerequisites:
|
Generally the bases useful to attend this course are provided by the various courses within a given chosen curriculum. |
Target skills and knowledge:
|
Aim of the course is to provide the student with the necessary tools to understand and analyze the main issues dealing with the physics of the Early Universe, both from a theoretical modeling point of view and from an observational point of view. Particular attention will be devoted to the most updated research topics within this research field. |
Examination methods:
|
Oral exam |
Assessment criteria:
|
Acquisition of the basic concepts of the course, ability of the student to elaborate in an original and independent way the concepts acquired, capacity of reasoning and of applying the tools provided by the course. |
Course unit contents:
|
General introduction. The problem of the initial conditions: primordial density perturbations at the origin of the formation of the Large Scale Structure of the Universe.
- Short recall of the main problems of the standard cosmological model
- Inflationary cosmology in the Early Universe as a solution to the problems of the standard model
Modeling:
- Inflationary models: vacuum energy and the inflation field; dynamics of a scalar field in a Friedman-Robertson-Walker Universe; possible realizations of the inflationary scenario
- Cosmological models of inflation and main features of the models within high-energy particle physics
- Observational predictions of the inflationary models: from the quantum perturbations in an expanding universe to the primordial density perturbations; generation of primordial gravitational waves and their observability (cosmological and interferometric probes).
Reheating phase and baryogengesis mechanisms
Delta-N and in-in formalisms for the study of cosmological perturbations. Example: primordial non-Gaussianity
Cosmological perturbations in General Relativity:
- scalar, vector and tensor perturbations
- gauge transformations
- Einstein equations linearly perturbed around the Robertson-Walker metric
Observational tests of the Early Universe |
Planned learning activities and teaching methods:
|
Lectures with a proposal of exercises and examples |
Additional notes about suggested reading:
|
The relevant parts of the course will be clearly identified in the various textbooks and notes of the teacher will be available for various parts of the course.
For some topics specific references in the literature will also be provided for those students who eventually want to have some further details. |
