TORRES-PAPAQUI, J. P. et al. What Do the Star Formation Histories of Galaxies Tell Us About the Starburst-AGN Connection?. Rev. mex. astron. astrofis [online]. 2013, vol.49, n.2, pp.311-332. ISSN 0185-1101.

We have determined the normal star formation histories (SFHs) for narrow emission line galaxies classified as star forming galaxies (SFGs), transition type objects (TOs), Seyfert 2s (Sy2s) and LINERs. The SFH varied with the activity type, following the mass of the galaxies and the importance of their bulge: LINERs reside in massive early-type galaxies, Sy2s and TOs in intermediate mass galaxies with intermediate morphological types, and SFGs are hosted in lower mass late-type spirals. Also, the maximum star formation rate in the past was found to increase with the virial mass within the aperture (VMA). This correlation suggests that the bulges and the supermassive black holes at the center of galaxies grow in parallel, in good agreement with the relation M_BH-σ*.
