Journal ArticleDOI
Particle physics models of inflation and the cosmological density perturbation
David H. Lyth,Antonio Riotto +1 more
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.
Journal ArticleDOI
Non-Gaussianity from inflation: theory and observations
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.
Journal ArticleDOI
Constraining warm dark matter candidates including sterile neutrinos and light gravitinos with WMAP and the Lyman-{alpha} forest
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.
Journal ArticleDOI
Towards a complete theory of thermal leptogenesis in the SM and MSSM
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.
Journal ArticleDOI
Second-Order Cosmological Perturbations from Inflation
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.
