Black hole growth in the local Universe

Do AGN phases affect the evolution of galaxies? I will present some
recent results based on data from the Sloan Digital Sky Survey and the
Galaxy Zoo project to argue that the question has multiple answers and
that it strongly depends on galaxy morphology. We now have a general
picture of the ongoing formation and evolution of early-type galaxies
via a specific evolutionary sequence starting in the blue cloud and
ending in the low-mass end of the red sequence. This evolutionary
sequence includes a Seyfert AGN phase in the green valley, but this
phase occurs too late after the shutdown of star formation to be
responsible for it. Thus, the bulk of black hole accretion in
low-redshift early-type galaxies occurs in post-starburst objects, and
not concurrent with star formation. The majority of black hole growth
in the local Universe however is associate with late-type galaxies and
likely has a fundamentally different connection to the host galaxy
evolution, if any.
