Recent simulations which include AGN feedback and postulate that AGN form during galaxy mergers, have received much attention recently because of their success in reproducing a range of observed properties of both AGN and galaxies. A clear prediction of these simulations is that there should be an association between AGN and starburst events. Examples of such composite objects are rather isolated in the literature however. I will present the latest work on the subject and summarize the surveys that will be used to tackle this open question in the future.
