Abstract

Supermassive black holes associated with active galactic nuclei (AGN) affect galaxy evolution via radio-emitting jets that influence star formation (a process known as feedback). The XXL-S field was observed at 2.1 GHz with the Australia Telescope Compact Array for the purpose of measuring the evolution of feedback from high excitation radio galaxies (HERGs) and
low excitation radio galaxies (LERGs) therein. The LERGs display weak evolution, while the HERGs demonstrate stronger evolution, but the latter is weaker compared to previous HERG evolution measurements. This implies that feedback from HERGs is more prominent in the nearby universe than previously thought.
