Title: Radio-AGN evolution and feedback across cosmic time

Abstract: It is now widely accepted that AGN, in particular radio-AGN, play a crucial role in the evolutionary lifecycles of massive galaxies; however, much remains to be understood about exactly how these processes work. I will review our understanding of this topic, and in particular will focus on the advances in our understanding being made possible by the vast, high-sensitivity radio catalogues being produced by the LOFAR Two-Metre Sky Survey (LoTSS), including its dedicated Deep Fields. These provide a remarkable resource to understand the triggering, evolution and feedback effects of radio-AGN, when combined with high-quality multi-wavelength datasets and spectroscopic surveys. I will show the relationships between radio-AGN activity and other host galaxy properties, including stellar mass, black hole mass, star-formation rate, environment and galaxy morphology, and will discuss the implications of these results for radio-AGN fuelling and the radio-AGN feedback cycle.
