Cosmic Structure, Averaging and Dark Energy
by

Publisher: arXiv
Number of pages: 55

Description:
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.

This text covers the theory of cosmological perturbations, which describes the generation of inhomogeneities in the early universe and their evolution until the current time. The theory is applied to three classes of models of the early universe.

Cosmology and particle physics are deeply interrelated. Among the common problems are dark energy, dark matter and baryon asymmetry of the Universe. We discuss these problems in general terms, and concentrate on several particular hypotheses.
