FRII source

There is mounting evidence that AGN feedback is important in galaxy evolution. Radio-mode feedback is thought to be particularly significant because the mechanical action of the expanding lobes provides a strong coupling mechanism between AGN energy and the surrounding environment. In order to quantify this feedback, detailed models of radio lobe evolution are required. Self-similar analytic models exist for large FRII radio sources but the evolution of the young precursor radio sources is not yet fully understood. The task now is to develop a young source model and rigorously test it against the observed distribution of sources on the radio power - linear size (PD) diagram.
