I give an overview of the effects of neutrino masses in cosmology, focusing on the role they play in the evolution of cosmological perturbations. I discuss how recent observations of the cosmic microwave background anisotropies and the large-scale matter distribution can probe neutrino masses with greater precision than current laboratory experiments. I describe several new techniques that will be used to probe cosmology in the future, as well as recent advances in the computation of the nonlinear matter-power spectrum and related observables.

Updated results on neutrino mass and mass hierarchy from cosmology with Planck 2018 likelihoods (2019, background): “Effects of massive neutrinos on cosmological observables have been extensively studied in the literature [16–22] and these effects help in constraining the sum of neutrino masses.”
An efficient implementation of massive neutrinos in non-linear structure formation simulations (2012, background): “In each case the CMB anisotropy power spectrum is affected (Lesgourgues & Pastor 2006; Wong 2011), which has allowed CMB observations to set what is perhaps the most robust constraint on the neutrino mass, ∑ mν < 1.3 eV (Komatsu et al. 2011).”
Neutrino electromagnetic interactions: A window to new physics (2014, background): “…data in the framework of the standard Cold Dark Matter model with a cosmological constant (ΛCDM) disfavors neutrino masses larger than some fraction of eV, but the value of the upper bound on the sum of neutrino masses depends on model assumptions and on the considered data set (see Wong (2011)).”
