Starburst-AGN mixing - II. Optically selected active galaxies

Davies, Rebecca; Kewley, Lisa; Ho, I-Ting; Dopita, Michael


We use four galaxies from the Calar Alto Legacy Integral Field Area survey with clear signs of accretion on to supermassive black holes to investigate the relative contribution of star formation and active galactic nucleus (AGN) activity to the line emission of each galaxy as a function of radius. The combination of star formation and AGN activity produces curved 'mixing sequences' on standard optical diagnostic diagrams, and the fraction of emission due to AGN activity decreases smoothly with...[Show more]
