9 The Nobel Prize in Physics 2002 Information for the Public October 8, 2002 This year's Nobel Prize in Physics is concerned with the discoveries and detection of cosmic particles and radiation, from which two new fields of research have emerged, neutrino astronomy and X-ray astronomy. The Prize is awarded with one half jointly to: Raymond Davis Jr, Department of Physics and Astronomy, University of Pennsylvania, Philadelphia, USA, and Masatoshi Koshiba, International Center for Elementary Particle Physics, University of Tokyo, Japan, “for pioneering contributions to astrophysics, in particular for the detection of cosmic neutrinos”, and the second half to Riccardo Giacconi, Associated Universities, Inc., Washington, DC, USA, “for pioneering contributions to astrophysics, which have led to the discovery of cosmic X-ray sources”. Here is a description of the scientists' award-winning achievements. The Sun by Neutrinograph

10 Skyplot of Reconstructed Neutrino Induced Events SuperKamiokande (A. L. Stachyra, 2002) MACRO (M. Ambrosio et al, 2001)

11 Observation Techniques nebula γ ray bursts Cosmic Ray Showers

12 Neutrinos do not have electromagnetic interactions Galactic Magnetic Field vs Gravitational Lensing 1pc=3.086 10 16 m

13 The Origin of Cosmic Rays Cosmic Accelerators

14 Possible Origin of the Ultra Energetic Cosmic Rays Decays of particles produced by topological defects or relic particles Z decays due to UHE neutrino interactions on relic ν’s UHECR photopion production on CMB

15 KANGAROO multi-wavelength spectrum TeV γ-rays of hadronic origin ?

16 H. Voelk- TAUP2003 TeV γ-rays of hadronic origin ? Crab Nebula: Another indication ?

17 Neutrinos would verify the hadronic acceleration scenario

18 Dark Matter and Neutrinos WIMPS accumulated inside celestial bodies decaying in neutrinos

19 Neutrino Sources Active Galactic Nuclei Cataclysmic Phenomena Dark Matter of the Universe Relics of the Grand Unification Era THE UNEXPECTED Diffused fluxes Point sources Background Environmental noise atmospheric muons atmospheric neutrinos
