Suggested model of radio-galaxy growth stimulated by recurrent activity. The core is marked with a black dot. The lobes created in the original phase of activity are marked in black, and the lobes created in the restarted phase of activity are marked in gray. Phase I: FRII RG in its original phase of activity. Phase II: RG after the AGN activity got quenched and restarted. The inner double (gray) propagates on the interior of the relic cocoon (black). Phase III: Restarted jet reaches the thermal medium on the outside of the relic cocoon. The evolution in the restarted phase continues in a way similar to a regular FRII RG. The relic matter becomes an “extension” of the newly formed double. A contrast of spectral age between the head and the extension should be observed. Phase IV: Restarted phase continues the growth. The relic matter expends so much energy that it can no longer be observed. The RG appears as a single-double. According to this model, J1528+0544 reached phase III before the restarted activity in the “intermediate” phase became quenched.
