A Stellar Dynamical Measurement of the Black Hole Mass in the Maser Galaxy NGC 4258
Christos Siopis, Karl Gebhardt, Tod R. Lauer +13
We determine the mass of the black hole at the center of the spiral galaxy NGC 4258 by constructing axisymmetric dynamical models of the galaxy. These models are constrained by hig…
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…
