We propose to investigate luminous extended emission-line regions (EELRs) that are found exclusively around FR II radio sources (AGNs with strong radio jets). The current theory suggests that the EELRs consist of gas driven out of the AGN host galaxy by blast waves that accompany the initiation of radio jets. The amount of the gas ejected in such activity can be on the order of the mass of the interstellar medium in the Milky Way. Such massive outflows must have a significant impact on the growth of the central supermassive black holes and star formation rate in the system. To better understand the triggering mechanism and early evolution of these outflows. Here we propose to use the Integral Field Unit (IFU) on Gemini to study the EELRs around very young (~ 10^4 years) radio galaxies. We ask for 7 hours of Gemini time to observe 3 interesting CSS targets.
