Lecture on Neutrino Astronomy

Basic purpose of this lecture is to present on Neutrino Astronomy. Neutrino astronomy is the branch of astronomy that observes astronomical objects with neutrino detectors in special observatories. Here briefly focus on why Neutrinos: Questions in ultra high energy astrophysics; Source of UHE cosmic rays; GRBs; AGN and Other Physics Questions – DM, Top Down models, etc. Astrophysical sources of high-energy neutrinos have not been observed directly, but their existence can be inferred from the properties of cosmic rays.
