Abstract:
We present a stellar dynamical estimate of the black hole (BH) mass in
the Seyfert 1 galaxy, NGC 4151. We analyze ground-based spectroscopy
as well as imaging data from the ground and space, and we construct
three-integral axisymmetric models in order to constrain the BH mass
and mass-to-light ratio.
Description:
We made use of a set of ground-based BVR images from the MDM 1.3m
McGraw-Hill telescope as well as Hubble Space Telescope (HST) imaging
data obtained with the High Resolution Channel (HRC) of the Advanced
Camera for Surveys (ACS).
