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

  1. Apply the theory of cosmic perturbation to the problem of the formation of the structure of the universe.
  2. Distinguish and analyse the problems of the classic Big Bang theory.
  3. Recognise the basics of the theory of cosmic perturbation theory.

Content

  1. Introduction to Cosmology: the Big Bang theory, Hubble's law, nucleosynthesis. Cosmic background radiation.
  2. Cosmic Expansion: models, scale factors, redshift, measurements of H.
  3. Cosmological equations: continuity equation and state equation,
  4. Friedmann equation, acceleration, cosmological parameters, dark matter and energy.
  5. Spacetime measurements: cosmic distances, horizons, age and volume.
  6. Problems with the Big Bang theory: baryogenesis, inflation, dark matter, origen of structures.
  7. Structure formation: gravitational collapse, instability hierarchical, power spectrum, acoustic oscillations, galaxy formation, numerical simulations, halo models.

Methodology

Assessment

Assistance to classes is a requirement.

Some parts of the class will require class projects and some other parts to present problems.

This can be both writen or oral presentation to a total value of 50%.

The other 50% is a written exam.

There will be a resit exam for 50% of the grade.

In order to take part in the resit exam you must have obtained a mark of 3.5 or higher.
