Abstract
The main purpose of this research was to investigate how energetic processes associated with active galactic nuclei (AGN) are related to those due to nuclear or circumnuclear star formation activity. Photometric and spectroscopic data were used to discriminate between these processes in a sample of starburst, infrared galaxies and AGNs. Here, we propose new diagnostic diagrams based on the 7.7 μm polycyclic aromatic hydrocarbon emission band, the L(MIR,FIR) infrared ratio and the q parameter. The diagnostic diagrams allow us to discriminate the behavior of quasars and Seyfert 1-Seyfert 2 galaxies from starbursts and LIRGs-ULIRGs objects.Similar Articles
