It is commonly assumed that the energy density of the Universe was dominated by radiation
between reheating after inflation and the onset of matter domination 54,000 years later …

A number of anomalous results in short-baseline oscillation may hint at the existence of one
or more light sterile neutrino states in the eV mass range and have triggered a wave of new …

We revisit the decoupling of neutrinos in the early universe with flavour oscillations. We
rederive the quantum kinetic equations which determine the neutrino evolution based on a …

From a theoretical point of view, there is a strong motivation to consider an MeV-scale
reheating temperature induced by long-lived massive particles with masses around the …

We present an up-to-date global analysis of data coming from neutrino oscillation and non-
oscillation experiments, as available in April 2018, within the standard framework including …

A bstract We present the results of an updated fit of short-baseline neutrino oscillation data
in the framework of 3+ 1 active-sterile neutrino mixing. We first consider ν e and\({\overline …

Neutrinos, being the only fermions in the Standard Model of Particle Physics that do not
possess electromagnetic or color charges, have the unique opportunity to communicate with …

This paper presents cosmological results based on full-mission Planck observations of
temperature and polarization anisotropies of the cosmic microwave background (CMB) …

We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting
views and insights from all disciplines involved—cosmology, astrophysics, nuclear, and …

Large, nonstandard neutrino self-interactions have been shown to resolve the∼ 4 σ tension
in Hubble constant measurements and a milder tension in the amplitude of matter …
