Scientific paper

The bulge-BH mass relation in galaxies is poorly understood. Our discovery of low-luminosity AGN in post-starburst, post-merger galaxies suggests that any rapid growth phase of the AGN has ended roughly with the star formation. Is this connection between BH and bulge evolution causal, as proposed by a new crop of merger-induced, AGN-feedback models? Testing these models requires 1) dating, within the first few 100 Myr, the starburst's age, 2) searching for the declining AGN in X-rays to limit obscuration, and 3) using high-resolution X-ray imaging to exclude the starburst's hot gas as the X-ray source. We propose to look for AGN in four post-merger, post-starburst galaxies whose young stellar clusters place a tight upper-limit on the time elapsed since the starburst.
