Modern cosmology has created a tight link between particle physics / field theory and a wealth of new observational data on the structure of the Universe. These lecture notes focus on some of the most important aspects concerning the connection between theory and observations.

Basics of inflationary models for the early universe, concentrating on the generation of density fluctuations from scalar-field dynamics. The subsequent gravitational dynamics of these fluctuations in dark matter in a Friedmann model are described.

We review cosmological inflation and its realization in quantum field theory and string theory. We describe two intertwined approaches to the physics of inflation: from the bottom up in effective field theory, and from the top down in string theory.

We review the question of primordial magnetic fields and consider the limits set on their strength by the observational data. The various mechanisms of pre-recombination magnetogenesis are presented and their advantages and shortcomings are debated.

The main motivations and challenges related with the physics of large-scale magnetic fields are briefly analyzed. The interplay between large-scale magnetic fields and scalar CMB anisotropies is addressed with specific attention on recent progresses.
