An Introduction into the Theory of Cosmological Structure Formation
by Christian Knobel
Publisher: arXiv 2012
Number of pages: 102
This text aims to give a pedagogical introduction into the main concepts of the theory of structure formation in the universe. The text is suited for graduate students of astronomy with a moderate background in general relativity. A special focus is laid on deriving the results formally from first principles.

Ekpyrotic and cyclic cosmologies provide theories of the very early and of the very late universe. In these models, the big bang is described as a collision of branes - and thus the big bang is not the beginning of time.

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.

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.

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.
