Description
High energy astrophysical neutrinos can provide essential information on the source location, acceleration mechanism and composition of the Cosmic Rays and on the structure of astrophysical jets. Since neutrinos rarely interact, huge detectors covering an area of more than 1 km2 are required to make a statistically significant measurement. The South Pole in Antarctica is the host of IceCube, the first 1 km2 scale high energy neutrino detector that was completed in 2011. In this talk I will review the main mechanisms that may lead to the production of High Energy Neutrinos (TeV-PeV) from astrophysical sources like Gamma-Ray Bursts (GRBs), Microquasars and other sources. I will give an overview on the characteristic of these emissions and an estimate of the fluxes and rates that can be detected at the future and present neutrino telescopes. I will discuss the constraints given on these sources from the results of IceCube.
