The Black Hole Mass and Extreme Orbital Structure in NGC1399
Karl Gebhardt, Tod R. Lauer, Jason Pinkney +12
The largest galaxies, and in particular central galaxies in clusters, offer unique insight into understanding the mechanism for the growth of nuclear black holes. We present Hubble…
The Centers of Early-Type Galaxies with HST. V. New WFPC2 Photometry
Tod R. Lauer, S. M. Faber, Karl Gebhardt +14
We analyze HST+WFPC2 images of 77 early-type galaxies. Brightness profiles are classed into "core" or "power-law" forms. Cores are typically rounder than power-law galaxies. Nearly…
Black Hole Mass Determinations From Orbit Superposition Models are Reliable
Douglas Richstone, Karl Gebhardt, Monique Aller +13
We show that orbit-superposition dynamical models (Schwarzschild's method) provide reliable estimates of nuclear black hole masses and errors when constructed from adequate orbit l…
Kinematics of Ten Early-Type Galaxies from HST and Ground-Based Spectroscopy
Jason Pinkney, Karl Gebhardt, Ralf Bender +11
We present stellar kinematics for a sample of 10 early-type galaxies observed using the STIS aboard the Hubble Space Telescope, and the Modular Spectrograph on the MDM Observatory…
Axisymmetric Dynamical Models of the Central Regions of Galaxies
Karl Gebhardt, Douglas Richstone, Scott Tremaine +12
We present axisymmetric, orbit superposition models for 12 galaxies using data taken with the Hubble Space Telescope (HST) and ground-based observatories. In each galaxy, we detect…
