Abstract

In the past 10-15 years our view of AGN has significantly evolved thanks to the combination of new observations and models. X-ray, infrared and sub-mm data have been crucial to peer into the inner region of AGN and study the properties of the tori, circum-nuclear disks and nuclear outflows. In this talk I will summarize our current view of nuclear obscuration in AGN, focusing on the variations of the torus properties with gas phase. I will also present preliminary results from a new project aimed to characterize nuclear outflows in a sample of nearby quasars and study their impact in the stellar populations, on-going star formation and molecular gas reservoirs of the galaxies.
