abstract
We consider the prospects for observing the effects of quantum decoherence in high-energy (TeV-PeV) neutrinos from astrophysical sources. In particular, we study Galactic sources of electron anti-neutrinos produced in the decay of ultra-high energy neutrons. We find that next generation neutrino telescopes should be capable of placing limits on quantum decoherence effects over multi-kiloparsec baselines, surpassing current bounds by a factor of $10^{12}$ to $10^{33}$, depending on the model considered.

Visible inelasticity as a probe of tau flavor content of astrophysical neutrinos
Visible inelasticity in starting tracks can statistically separate tau and muon neutrino events, yielding competitive sensitivity to the tau-to-muon flux ratio with current IceCube exposures.
