Abstract

It is shown how high energy neutrino beams from very distant sources can be utilised to learn about many neutrino properties such as lifetimes, mass hierarchy, mixing, minuscule pseudo-Dirac mass splittings and other exotic properties. In addition, the production mechanism of neutrinos in the astrophysical sources can also be elucidated.
