Journal ArticleDOI
Neutrinos in cosmology
TL;DR: In this paper, the cosmological implications of neutrinos are reviewed at a different level of scrutiny, including neutrino mass, neutrini mass limits and their effect on primordial nucleosynthesis.
Journal ArticleDOI
Massive sterile neutrinos as warm dark matter
Alexander D. Dolgov,S.H. Hansen +1 more
TL;DR: In this paper, it was shown that massive sterile neutrinos mixed with the ordinary ones may be produced in the early universe in the right amount to be natural warm dark matter particles.
Journal ArticleDOI
Cosmological bounds on neutrino degeneracy improved by flavor oscillations
Alexander D. Dolgov,S. H. Hansen,Sergio Pastor,S. T. Petcov,Georg G. Raffelt,Dmitry V. Semikoz +5 more
TL;DR: In this article, the authors studied three-flavor neutrino oscillations in the early universe and found that effective flavor equilibrium between all active neutrinos species is established well before the big-bang nucleosynthesis (BBN) epoch.
Journal ArticleDOI
Cosmology and elementary particles
TL;DR: In this paper, the restrictions on elementary particle properties which can be derived from cosmological and astrophysical data are considered, and the inverse relations between micro- and macrophysics are also discussed, in particular the origin of the baryon asymmetry of the universe.
Journal ArticleDOI
Asymmetric inflationary reheating and the nature of mirror universe
TL;DR: In this paper, the authors show that the asymmetric reheating can be related to a difference of the electroweak symmetry breaking scales in the two sectors, which is needed for a solution of the neutrino puzzles in this picture.
