Improved hot dark matter bound on the QCD axion
A Notari, F Rompineve, G Villadoro - Physical Review Letters, 2023 - APS
We obtain a reliable cosmological bound on the axion mass ma by (1) deriving the
production rate directly from pion-pion scattering data, which overcomes the breakdown of …

Cosmic neutrino background detection in large-neutrino-mass cosmologies
The cosmic neutrino background (CNB) is a definite prediction of the standard cosmological
model and its direct discovery would represent a milestone in cosmology and neutrino …

Neutrino cosmology after DESI: tightest mass upper limits, preference for the normal ordering, and tension with terrestrial observations
JQ Jiang, W Giare, S Gariazzo, MG Dainotti… - arXiv preprint arXiv …, 2024 - arxiv.org
The recent DESI Baryon Acoustic Oscillation measurements have led to tight upper limits on
the neutrino mass sum, potentially in tension with oscillation constraints requiring $\sum m …

A new probe of relic neutrino clustering using cosmogenic neutrinos
We propose a new probe of cosmic relic neutrinos (CνB) using their resonant scattering
against cosmogenic neutrinos. Depending on the lightest neutrino mass and the energy …

Living at the Edge: A Critical Look at the Cosmological Neutrino Mass Bound
D Naredo-Tuero, M Escudero… - arXiv preprint arXiv …, 2024 - arxiv.org
Cosmological neutrino mass bounds are becoming increasingly stringent. The latest limit
within $\Lambda $ CDM from Planck 2018+ ACT lensing+ DESI is $\sum m_\nu< 0.072\,{\rm …

Model marginalized constraints on neutrino properties from cosmology
E Di Valentino, S Gariazzo, O Mena - Physical Review D, 2022 - APS
We present robust, model-marginalized limits on both the total neutrino mass (∑ m ν) and
abundances (N eff) to minimize the role of parametrizations, priors and models when …

Influence of local structure on relic neutrino abundances and anisotropies
Gravitational potentials of the Milky Way and extragalactic structures can influence the
propagation of the cosmic neutrino background (CNB). Of particular interest to future CNB …

A seesaw model for large neutrino masses in concordance with cosmology
M Escudero, T Schwetz, J Terol-Calvo - Journal of High Energy Physics, 2023 - Springer
A bstract Cosmological constraints on the sum of the neutrino masses can be relaxed if the
