Abstract


Gamma Ray Bursts (GRBs) and Cosmic Rays (CRs) are easily understandable. Solid observations of quasars and micro-quasars show how these objets emit “Cannonballs” (CBs), though the underlying mechanisms are not theoretically well understood. The assumption that core-collapse supernovae emit CBs plus some trivial relativistic kinematics provide a success ...
