Abstract / Description:The radiative cooling of electrons responsible for the nonthermal synchrotron
emission of large scale jets of radiogalaxies and quasars requires quasi
continuous (in time and space) production of relativistic electrons throughout
the jets over the scales exceeding 100 kpc. While in the standard paradigm of
large scale jets this implies in situ acceleration of electrons, in this letter
we propose a principally different ``non-acceleration'' origin of these
electrons, assuming that they are implemented all over the length of the jet
through effective development of electromagnetic cascades initiated by
extremely high energy gamma-rays injected into the jet from the central object.
This scenario provides a natural and very economic way to power the jets up to
distances of 100 kpc and beyond.
