Title: The High Mass End of the Black Hole Mass - Stellar Velocity Dispersion Relation in AGNs

Abstract: In 2006, we started a program with Gemini/NIFS to obtain stellar velocity dispersions for all high redshift (z > 0.06) AGNs with secure reverberation-mapping measurements of the BH mass. Our program has been very successful: the two galaxies for which data are already in hand (four are in the queue for 2010A but have yet to be observed) have produced interesting results that have been published. In particular, in addition to showing peculiarities in the circumnuclear stellar population, the galaxy with the most massive black hole appears to lie significantly above the extrapolation of the M-sigma relation defined by less massive systems. The present request of 8.89 hours will complete the program by targeting the two remaining reverberation-mapped AGNs for which these studies are feasible.
