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.
