Abstract
Elucidating the relationship between intense star formation and the AGN phenomenon is crucial to our understanding of the formation of galaxies and their supermassive black holes (SMBHs) in the early Universe. There have been many suggestions that starbursts play a powerful role in nearby Seyfert 2 galaxies. However, the role that starburst play in more powerful distant AGN is not known. This contribution shows how deep spectroscopy and imaging taken with OSIRIS and EMIR will help to determine whether the ubiquitous link between star formation and nuclear activity established for nearby Seyferts extends to more powerful distant AGN.
