Primordial Magnetogenesis
by Alejandra Kandus, Kerstin E. Kunze, Christos G. Tsagas
Publisher: arXiv 2011
Number of pages: 107
Description:
We review the question of primordial magnetic fields and consider the limits set on their strength by the current observational data. The various mechanisms of pre-recombination magnetogenesis are presented and their advantages and shortcomings are debated. We consider both classical and quantum scenarios, that operate within as well as outside the standard model, and also discuss how future observations could be used to decide whether the large-scale magnetic fields we see in the universe today are truly primordial or not.

Inflation and String Theoryby Daniel Baumann, Liam McAllister - arXiv
We review cosmological inflation and its realization in quantum field theory and string theory. We describe two intertwined approaches to the physics of inflation: from the bottom up in effective field theory, and from the top down in string theory.

Cosmic Microwave Background Anisotropies up to Second Orderby Nicola Bartolo, Sabino Matarrese, Antonio Riotto - arXiv
These notes present the computation of the system of Boltzmann equations describing the evolution of the photon, baryon and cold dark matter fluids up to second order in perturbation theory. They follow the time evolution of the CMB anisotropies.
