Speaker
Christian Wagner
(MPA)
Description
After reviewing the basics of neutrino physics in the context of cosmology, Christian will focus on neutrino effects on the large scale structure of the universe. Especially, he will discuss how the matter power spectrum and galaxy cluster abundance are altered by the total mass of the neutrinos. Along the way, predictions of the effects using linear theory as well as N-body simulations are presented. Christian will conclude by summarizing the latest observational constraints derived from various cosmological data sets including a discussion of their possible systematics.
