| Abstract: |
A fraction of galactic nuclei which are optically classified as starburst or as "normal" nuclei show indications for the presence of a powerful AGN when observed in the X-rays, in the infrared or in the radio. I will discuss these evidences obtained from past and new observations and suggest that these galaxies are probably hosting AGN which are obscured in all directions and, therefore, do not produce the AGN signatures typically observed in the optical. An important implication of these findings is that optical surveys have probably underestimated the fraction of AGN hosted in starburst and normal galaxies in the local universe. I will also discuss important implications on the starburst-AGN connection and, in particular, the relation between AGN obscuration, starburst activity and non axisymmetric morphologies of the host galaxies. |
