Magnetar-powered Neutrinos and Magnetic Moment Signatures at IceCube

Abstract

The IceCube collaboration pioneered the detection of $\mathcal{O}(\text{PeV})$ neutrino events and the identification of astrophysical sources of high-energy neutrinos. In this study, we explore scenarios in which high-energy neutrinos are produced in the vicinity of astrophysical objects with strong magnetic field, such as magnetars. While propagating through such magnetic field, neutrinos experience spin precession induced by their magnetic moments, and this impacts their helicity and flavor composition at Earth. Considering both flavor composition of high-energy neutrinos and Glashow resonance events we find that detectable signatures may arise at neutrino telescopes, such as IceCube, for presently unconstrained neutrino magnetic moments in the range between $\mathcal{O}(10^{-15}){\mu }_B$ and $\mathcal{O}(10^{-12}){\mu }_B$.
