Stochastic acceleration of cosmic rays in region of relativistic jet deceleration in blazars

Abstract

We investigate an acceleration of relativistic particles (cosmic rays) in turbulent magnetized plasma in central regions of blazars, created by interaction of relativistic jets of FRI radio galaxies with circumnuclear and/or interstellar medium. Especially, we consider interaction of fast particles with Alfven waves in the frame of the second order Fermi mechanism of cosmic ray acceleration.
