The connection between cosmology and neutrino physics

TL;DR

Cosmology offers a powerful way to test neutrino physics, with current measurements and future prospects including potential direct detection of the cosmic neutrino background and its anisotropies.

Contribution

This paper reviews the current status of cosmological neutrino measurements and discusses future experimental prospects and the potential for direct detection of the cosmic neutrino background.

Findings

Current cosmological neutrino constraints are improving.

Future experiments may detect the cosmic neutrino background directly.

The interplay between cosmology and neutrino physics enhances understanding.

Abstract

Cosmology provides a unique and very powerful laboratory for testing neutrino physics. Here, I review the current status of cosmological neutrino measurements. Future prospects are also discussed, with particular emphasis on the interplay with experimental neutrino physics. Finally I discuss the possibility of a direct detection of the cosmic neutrino background and its associated anisotropy.
