THE EVOLUTION OF THE ACCELERATION MECHANISMS OF COSMIC RAYS AND RELATIVISTIC ELECTRONS IN RADIO GALAXIES

THE EVOLUTION OF THE ACCELERATION MECHANISMS OF COSMIC RAYS AND RELATIVISTIC ELECTRONS IN RADIO GALAXIES

There are estimated an efficacy for dif­ferent acceleration mechanisms of e- and p-cosmic rays (CRs) in radio galaxies, using an evolution model for jet gaps and shock fronts with a turbulence. It is shown that diffusion shock acceleration of the CRs is the most effi­cient mechanism in the FR II rad...
