Neutrino Astrophysics
A general overview of neutrino physics and astrophysics is given, starting with a historical account of the development of our understanding of neutrinos and how they helped to unravel the structure of the Standard Model. We discuss why it is so important to establish if neutrinos are massive and introduce the main scenarios to provide them a mass. The present bounds and the positive indication...
متن کاملNeutrino Conversion and Neutrino Astrophysics *
We consider main ingredients which determine neutrino transformations in media. Strong transformations relevant for the astrophysics can be due to large depth oscillations, resonance conversion, parametric resonance effect, interplay of oscillations and inelastic collisions. Properties of transitions are discussed using the graphic representation. The applications of the transitions to supernov...

The observation of neutrinos is an experimental challenge due to their weak interactions that makes them elusive particles. Though they are difficult to detect, they are excellent probes to observe the most distant sources and their interior. Until now only MeV extra-terrestrial neutrinos have been observed from the Sun and SN1987A. Nevertheless there is growing activity to build detectors for ...
متن کاملHigh Energy Neutrino Astrophysics
Since early this century it has been known that a steady stream of charged nuclei, and to a lesser extent electrons and photons, reaches the Earth. The origin of the cosmic radiation, however, has not be explained satisfactorily. Finding an answer to this apparently simple question is complicated by the fact that extensive knowledge of several physical disciplines is required for an appropriate...
