Titre |
Modern Neutrino Cosmology |
|
Résumé |
Neutrinos are ubiquitous in cosmology and they always represent a substantial
fraction of the energy density of the Universe. This makes cosmology a key arena to
test the properties of the most elusive particles in the Standard Model. In this
talk, I will begin by first reviewing the various ways in which neutrinos impact
cosmological observables. I will discuss the origin of the cosmic neutrino
background, and how neutrino physics can alter BBN and the CMB. I will then discuss
three topics that I find timely in the context of precision cosmology, namely: 1)
what is the value of Neff in the Standard Model and how do we calculate it, 2) what
can cosmological observations tell us about BSM neutrino interactions, and 3) how
robust are the very stringent cosmological neutrino mass bounds. |
