Dissecting Galaxies: Spatial and Spectral Separation of Emission Excited by Star Formation and AGN Activity
Rebecca L. Davies, Brent Groves, Lisa J. Kewley +13
The optical spectra of Seyfert galaxies are often dominated by emission lines excited by both star formation and AGN activity. Standard calibrations (such as for the star formation…
