« Bursty stellar populations and obscured AGN in local galaxy bulges: an SDSS perspective »

A popular model for the coevolution of bulges and supermassive black holes is one in which a galaxy merger leads to the inflow of gas which fuels a strong starburst, followed by an AGN phase in which the black hole grows significantly. I will present some recent results on the stellar populations of AGN hosts in the SDSS spectroscopic galaxy catalogue, which use a new, high signal-to-noise ratio spectral diagnostic of recent star formation history.
