Title of the communication: Jet and radio lobe analytical modelling
Preliminary abstract (12 lines max.):
An approximate approach to the modelling of jet and large-scale
structure evolution of powerful extragalactic radio sources will be presented.
It is assumed that two plasma jets propagate from the core through the
ambient medium, create a shock front at the jet head and deposit constant
fractions of the jet energy into a lobe in the forms of cosmic ray electrons
and ions, thermal particles and magnetic fields. The whole forming lobe is
approximated by a range of adjacent volume elements that evolve individually
and sideways only. From the pressure and energy balance geometrical
properties of this evolution are found as well as energy and synchrotron
luminosity of the entire lobe. Classical and relativistic description of the
jet propagation and various physical parameters in the jet and the lobe will
be discussed in the framework of the presented model.
