Solution To The Cosmic Rays Puzzle ?

Recent observations provide compelling evidence that the bulk of the high energy cosmic rays (CRs) and gamma-ray bursts (GRBs) are co-produced by highly relativistic jets of plasmoids of stellar matter. These jets are launched by fall back matter on newly born neutron stars and stellar black holes in core collapse of stripped envelope massive stars with or without an associated supernova. The electrons in the plasmoids produce GRB pulses mainly by inverse Compton scattering of photons on their path, while magnetic reflection of the charged particles produces the high energy cosmic rays.
