High Energy Neutrino Astrophysics
I give a brief discussion of possible sources of high energy neutrinos of astrophysical origin over the energy range from ∼ 10 12 eV to ∼ 10 25 eV. In particular I shall review predictions of the diffuse neutrino intensity. Neutrinos from interactions of galactic cosmic rays with interstellar matter are guaranteed, and the intensity can be reliably predicted to within a factor of 2. Somewhat le...
متن کاملHigh Energy Neutrino Astrophysics
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...
متن کاملNuclear and High-energy Astrophysics
There has never been a more exciting time in the overlapping areas of nuclear physics, particle physics and relativistic astrophysics than today. Orbiting observatories such as the Hubble Space Telescope, Rossi X-ray Timing Explorer (RXTE), Chandra X-ray satellite, and the X-ray Multi Mirror Mission (XMM) have extended our vision tremendously, allowing us to see vistas with an unprecedented cla...
متن کاملVery-High Energy Gamma Astrophysics
High energy photons are a powerful probe for astrophysics and for fundamental physics under extreme conditions. During the recent years, our knowledge of the most violent phenomena in the Universe has impressively progressed thanks to the advent of new detectors for high energy gamma rays. Observation of γ-rays gives an exciting view of the high energy universe thanks to the current (AGILE) and...
