Prerequisites
Introduction to the Physics of the Cosmos
Objectives and Contextualisation
The course is intended to provide students with a introductory lectures to Cosmology. The standard Cosmological model, the open questions and the current research lines in the field.
Competences
- Formulate and tackle problems, both open and more defined, identifying the most relevant principles and using approaches where necessary to reach a solution, which should be presented with an explanation of the suppositions and approaches.
- Understand the bases of advanced topics selected at the frontier of high energy physics, astrophysics and cosmology and apply them consistently.
Learning Outcomes
- Apply the theory of cosmic perturbation to the problem of the formation of the structure of the universe.
- Distinguish and analyse the problems of the classic Big Bang theory.
- Recognise the basics of the theory of cosmic perturbation theory.
Content
- Introduction to Cosmology: the Big Bang theory, Hubble's law, nucleosynthesis. Cosmic background radiation.
- Cosmic Expansion: models, scale factors, redshift, measurements of H.
- Cosmological equations: continuity equation and state equation,
- Friedmann equation, acceleration, cosmological parameters, dark matter and energy.
- Spacetime measurements: cosmic distances, horizons, age and volume.
- Problems with the Big Bang theory: baryogenesis, inflation, dark matter, origen of structures.
- Structure formation: gravitational collapse, instability hierarchical, power spectrum, acoustic oscillations, galaxy formation, numerical simulations, halo models.
Methodology
Theory lectures and exercises.
Classwork and Homework.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment
This subject/module does not foresee the single assessment system.
Attendance to class is a mandatory requirement. 50% of the grade comes from assignments of problems and the completion of a research project in groups. The other 50% comes from a written exam. To be able to participate in the written exam, you must have obtained a grade higher than 3.5/10 in the assignments of problems and the project.
