Cosmic Structure, Averaging and Dark Energy
by David L. Wiltshire
Publisher: arXiv 2013
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.

Particle Physics Aspects of Modern Cosmology
by Robert H. Brandenberger - arXiv
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 notes focus on some aspects concerning the connection between theory and observations.

The Cosmic Web: Geometric Analysis
by Rien van de Weygaert, Willem Schaap - arXiv
The lecture notes describe the Delaunay Tessellation Field Estimator for Cosmic Web analysis. The high sensitivity of Voronoi/Delaunay tessellations to the local point distribution is used to obtain estimates of density and related quantities.

Cosmology for Particle Physicists
by U. A. Yajnik - arXiv
We begin with a recapitulation of General Relativity, and the Standard Model of Cosmology. This is followed by lectures on inflation, density perturbations, study of hot and cold relics decoupled from the remaining constituents, and baryon asymmetry.
