New physics in the neutrino sector might be necessary to address anomalies between
different neutrino oscillation experiments. Intriguingly, it also offers a possible solution to the …

We revisit cosmological constraints on the sum of the neutrino masses Σ m ν from a
combination of full-shape BOSS galaxy clustering [P (k)] data and measurements of the …

A bstract At present, cosmological observations set the most stringent bound on the neutrino
mass scale. Within the standard cosmological model (ΛCDM), the Planck collaboration …

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 …

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 …

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 …

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 …

Astroparticle physics is undergoing a profound transformation, due to a series of
extraordinary new results, such as the discovery of high-energy cosmic neutrinos with …

Low-redshift probes, such as baryon acoustic oscillations (BAO) and supernovae Ia
luminosity distances, have been shown to be crucial for improving the bounds on the total …

We explore a self-interacting neutrino cosmology in which neutrinos experience a delayed
onset of free-streaming. We use the effective field theory of large-scale structure (LSS) to …
