TL;DR
The paper discusses how the Glashow resonance can reveal the nature of cosmic neutrino sources by analyzing the electron antineutrino content in astrophysical fluxes, with implications from IceCube data.
Contribution
It introduces the concept of the 'Glashow resonometer' as a tool to probe the properties of cosmic neutrino sources based on resonance event rates.
Findings
No Glashow events observed in IceCube data.
The Glashow resonance rate depends on source environment and production mechanisms.
Potential to distinguish different astrophysical neutrino sources.
Abstract
The Glashow resonance at E_\nu=6.3 PeV is a measure of the \bar\nu_e content of the astrophysical neutrino flux. The fractional \bar\nu_e content depends on the neutrino production model at the cosmic neutrino source, and the environment at the source. Thus, the strength of the Glashow resonance event rate is a potential window into astrophysical sources. We quantify the "Glashow resonometer" and comment on the significance that no Glashow events are observed in the IceCube three-year data.
