Ekpyrotic and Cyclic Cosmology
by Jean-Luc Lehners
Publisher: arXiv 2009
Number of pages: 79
Description:
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. Before the big bang, there is an ekpyrotic phase with equation of state w=P/rho >> 1 during which the universe slowly contracts.

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.

Applied Cosmography: A Pedagogical Reviewby Yu. L. Bolotin, et al. - arXiv.org
Cosmography is in fact a kinematics of cosmological expansion. The effectiveness of cosmography lies in the fact that it allows, based on the observations, to perform a rigid selection of models that do not contradict the cosmological principle.
