(syllabus)
- Pills of relativity: the Friedmann Robertson-Walker Universe. Hubble Law. Redshift. Cosmological constant. Big Bang and cosmological horizon.
- Cosmological perturbations: Newtonian approximation and Jeans length. Transfer function.
- Cosmic Microwave background: primordial anisotropies; acoustic peaks; Sachs-Wolfe effect.
- More cosmic backgrounds: Radio, X, Infra-red and Gamma.
- Secondary anisotropies in the cosmic backgrounds: Ly-alpha forest; Gunn-Peterson Effect; reionization and 21 cm background; Sunayev-Zel'dovich effect.
- Large-Scale Structure of the Universe; statistical analyses of the galaxy distribution; probability distribution;
correlation functions; power spectra; peculiar velocities and redshift space distortions.
- Non-linear evolution of the cosmic perturbations; the Zel’dovich approximation; spherical collapse; N-body problem
and cosmological simulations.
- Virialized structures. The Press-Schechter theory (and its extension); cosmic structure mass function.
- Elements of galaxy formation: theory vs observations.
