Post-starburst quasars are broad-lined AGN that also display the strong Balmer jumps and high-order Balmer absorption lines characteristic of a very massive stellar population with ages on the order of 100 Myrs. These sources are rare, representing a few percent of the quasar population. Their significance is not yet clear; they may represent an evolutionary phase common to all galaxies that shows how the correlation between black hole mass and stellar bulge mass arises, or they may represent a rare but particularly violent interaction that leads to both massive starbursts and nuclear activity.
We explore the environment within 100 kpc of some 600 spectroscopically selected post-starburst quasars from the Sloan Digital Sky Survey in comparison to that of normal quasars.
