Origin of cosmological neutrino mass bounds: background perturbations
Toni Bertólez-MartÃnez, Ivan Esteban, Rasmi Hajjar +2
The cosmological upper bound on the total neutrino mass is the dominant limit on this fundamental parameter. Recent observations-soon to be improved-have strongly tightened it, app…

Detectable MeV Neutrino Signals from Neutron-Star Common-Envelope Systems
Ivan Esteban, John F. Beacom, Joachim Kopp
Common-envelope evolution - where a star is engulfed by a companion - is a critical but poorly understood step in, e.g., the formation pathways for gravitational-wave sources. Howe…

Neutrino Theory in the Precision Era
Asmaa Abada, Gabriela Barenboim, Toni Bertólez-MartÃnez +76
This document summarises discussions on future directions in theoretical neutrino physics, which are the outcome of a neutrino theory workshop held at CERN in February 2025. The st…
