Abstract
Elucidating the relationship between intense star-formation and the AGN phenomenon is crucial to our understanding of the formation and evolution of galaxies and their SMBHs in the early universe. The warm interstellar gas is an excellent probe of the feedback processes taking place in galaxies, in particular in AGNs and starbursts. Deep imaging taken with OSIRIS tuned at the emission lines Lyα , CIV, HeII, Hα, and optical collisional lines of AGNs (Seyferts, Radio Galaxies and QSOs) and Starbursts (ULIRGs-VLIRGs) will help to determine whether there is an evolutionary link between star-formation and nuclear activity.
