Abstract

Large optical surveys provide an unprecedsCeented census of galaxies in the local Universe, forming an invaluable framework into which more detailed studies of objects can be placed. But how useful are optical surveys for understanding the co-evolution of black holes and galaxies, given their limited wavelength coverage, selection criteria, and depth? Here we present work-in-progress comparing optical and mid-IR, diagnostics of three "unusual" low-z populations (luminous Seyferts, dusty Balmer-strong AGN, ULIRCs) with a set of ordinary star-forming galaxies from the SDSS. We address the questions "how well do the mid-IR and optical diagnostics of star formation and AGN strength agree?" and "to what extent do optical surveys allow us to include extreme, dusty, morphologically disturbed galaxies in our 'complete' census of BB-galaxy co-evolution?
