Cosmic Structure, Averaging and Dark Energy
by David L. Wiltshire
Publisher: arXiv 2013
Number of pages: 55
These lecture notes review the theoretical problems associated with coarse-graining the observed inhomogeneous structure of the universe at late epochs, of describing average cosmic evolution in the presence of growing inhomogeneity, and of relating average quantities to physical observables. In particular, a detailed discussion of the timescape scenario is presented.

Introductory lectures on cosmology for students specializing in particle physics are presented. Many important subjects are not covered because of lack of time and space but hopefully the lectures may serve as a starting point for further studies.

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.
