Objectives
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.
Skills
- 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.
