Main themes

Inhomogeneous universe, theory of cosmological perturbations, cosmic microwave background anisotropies, the early universe.

-The inhomegeneous universe
  * CMB anisotropies and large scale
structures
   * Horizon and flatness problem, the origin
of inhomogeneities
- Theory of cosmological perturbations
   * Gauge invariance, decomposition Scalar-
Vector-Tensor
   * Perturbed metric and Einstein equations
   * Density fluctuations, evolution and
power spectrum
- Cosmic microwave background anisotropies
   * Photon propagation
   * Perturbed Boltzmann equation
   * Angular power spectrum
   * Initial conditions and cosmological
parameter estimation

 

Aims

This course introduces the concepts required to understand modern Cosmology. It addresses the evolution of cosmological perturbations from the radiation era to the formation of galaxies, while discussing their imprints in the cosmic microwave background.
