Abstract :
One of the main open questions of galaxy evolution is how active galactic nuclei (AGN) can affect the ongoing star-formation and interstellar medium (ISM) properties of galaxies. To reproduce the properties of galaxies in the local universe, cosmological and semi-analytical models of galaxy formation and evolution find it necessary to use AGN feedback as a regulator of star formation, in the form of heating and outflows of the surrounding gas. To find observational evidence that AGN do have a significant role in regulating galaxy growth, we need to study the star formation and ISM properties of active galaxies. In this seminar I will present the main results from my research on the SFR and ISM properties of AGN across cosmic time.
