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...

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 ...

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...

From Ellsberg to Machina : Confronting decision models under ambiguitywith experimental evidenceHow do decision makers act and how should they act when confronted with uncertainty ?Economic behavior under uncertainty is often influenced by the informational structureof the decision context. Remarkably, the joint presence (juxtaposition or combination) oftwo sources of un...
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...
