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 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.

This text discusses the cosmological constant problem at a pedagogical but fully technical level. We review how the vacuum energy can be regularized in flat and curved space-time and how it can be understood in terms of Feynman bubble diagrams.

In this review we present a thoroughly comprehensive survey of recent work on modified theories of gravity and their cosmological consequences. We cover General Relativity, Scalar-Tensor, Einstein-Aether, Bimetric theories, TeVeS, Galileons, etc.
