TL;DR: A review of particle-theory models of inflation, and their predictions for the primordial density perturbation that is thought to be the origin of structure in the Universe is given in this paper.

TL;DR: A review of models of inflation and their predictions for the primordial non-Gaussianity in the density perturbations which are thought to be at the origin of structures in the Universe is given in this article.

TL;DR: In this paper, the authors presented constraints on the mass of WDM particles from a combined analysis of the matter power spectrum inferred from the high-resolution high signal-to-noise Lyman-$\ensuremath{\alpha}$ forest data of Kim et al. and the cosmic microwave background data of WMAP.

TL;DR: In this article, a thorough study of thermal leptogenesis was performed by adding finite temperature effects, RGE corrections, scatterings involving gauge bosons and by properly avoiding overcounting on-shell processes.

TL;DR: In this article, the cosmological perturbations generated during inflation up to second order in deviations from the homogeneous background solution are investigated. But the results indicate that detecting the non-Gaussianity in the cosmic microwave background anisotropies emerging from the second-order calculation will be a challenge for the forthcoming satellite experiments.
