Prospects for Flavor Measurements of High-Energy Astrophysical Neutrinos

Neutrinos of cosmic origin are excellent messengers to investigate the Universe. The IceCube experiment discovered TeV-PeV neutrinos of astrophysical origin which opened a new window to the cosmos. The flavor composition of astrophysical neutrinos carries information about the production mechanisms as well as possible beyond-standard-model effects during neutrino propagation. In the future, with boosted exposure, features of the flavor composition can be probed with the next-generation neutrino telescopes.  In this talk, I will discuss the prospects of identifying energy-dependent flavor composition and lifting the degeneracy of neutrinos and antineutrinos with Glashow Resonance.
