We discuss the prospects for next generation neutrino telescopes, such as IceCube, to measure the flavor ratios of high-energy astrophysical neutrinos. The expected flavor ratios at the sources are $\phi_{\nu_e}:\phi_{\nu_{\mu}}:\phi_{\nu_{\tau}} = 1:2:0$, and neutrino oscillations quickly transform these to $1:1:1$. The flavor ratios can be deduced from the relative rates of showers ($\nu_e$ charged-current, most $\nu_\tau$ charged-current, and all flavors neutral-current), muon tracks ($\nu_… 17 Citations Astrophysical neutrino flavor ratios in the presence of sterile neutrinos Astrophysical objects such as active-galactic nuclei (AGN) and gamma-ray bursts (GRBs) can be sources of high energy, astrophysical neutrinos.

The flavor of cosmic neutrinos may help unveil their sources and could reveal the presence of new physics in the neutrino sector. We consider impacts of next-generation neutrino detectors, including
Pseudo-Dirac neutrino scenario: Cosmic neutrinos at neutrino telescopes
Within the 'pseudo-Dirac' scenario for massive neutrinos the existence of sterile neutrinos which are almost degenerate in mass with the active ones is hypothesized. The presence of these sterile
