2 LHC ~E -2.7 ~E -3 ankle 1 part km -2 yr -1 knee 1 part m -2 yr -1 T. Gaisser 2005 Nature accelerates particles 10 7 times the energy of LHC! where?how? cosmic rays

3 flux of extra-galactic cosmic rays ankle  one 10 19 eV particle per km squared per sec per sr

4 flux = velocity x density :

5 Radiation Enveloping Black Hole p +  -> n +  + ~ cosmic ray + neutrino -> p +  0 ~ cosmic ray + gamma NEUTRINO BEAMS: HEAVEN & EARTH Neutrino Beams: Heaven & Earth

6 collapse of massive star produces a gamma ray burst highest energy particles

7 we know that : Black holes accelerate electrons: seen as synchrotron photons Black holes accelerate protons: seen as cosmic rays Black holes are surrounded by radiation fields and gases  cosmic beam dumps exist cosmic ray puzzle: where is the black hole ?

8 Waxman-Bahcall Flux in  + decay oscillations

9 detection method lattice of light sensors

10 events per km 2 year:

11 gamma ray bursts sources are transparent
