Cosmology http://www.superstringtheory.com/cosmo/index.html
From the Official String Theory Website. Basic and advanced tutorials on the age and structure of the universe, the Big Bang, and the relation of string theory to cosmology.

Cosmological Models http://it.arXiv.org/abs/gr-qc/9812046
The aim of this set of lectures is a systematic presentation of a 1+3 covariant approach to studying the geometry, dynamics, and observational properties of relativistic cosmological models.

Particle Aspects of Cosmology and Baryogenesis http://arxiv.org/abs/hep-ph/0302020
An introduction to particle aspects of cosmology with particular reference to primordial nucleosynthesis, dark matter and baryogenesis is provided. In particular, various scenarios-GUT baryogenesis, electroweak baryogenesis and baryogenesis through leptogenesis are reviewed.
