J. Magorrian,Scott Tremaine,Scott Tremaine,Douglas O. Richstone,Ralf Bender,G. A. Bower,Alan Dressler,Sandra M. Faber,Karl Gebhardt,Richard E. Green,Carl J. Grillmair,John Kormendy,Tod R. Lauer +12 more
TL;DR: In this article, the authors constructed dynamical models for a sample of 36 nearby galaxies with Hubble Space Telescope (HST) photometry and ground-based kinematics, assuming that each galaxy is axisymmetric, with a two-integral distribution function, arbitrary inclination angle, a position-independent stellar mass-to-light ratio, and a central massive dark object of arbitrary mass M•.
Journal ArticleDOI

TL;DR: In this article, the authors presented stellar kinematics for a sample of 10 early-type galaxies observed using the Space Telescope Imaging Spectrograph (STIS) aboard the Hubble Space Telescope, and the Modular Spectrogram on the MDM Observatory 24m telescope.

TL;DR: In this article, the authors present the best-fit model for NGC 1399, the central galaxy in Fornax, and find the best fit model contai ns a black hole of (5: 1� 0: 7)� 10 8 M� (at a distance of 21.1 Mpc).
