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…
Globular Clusters in Early-Type Galaxies with GMOS
Terry Bridges, Mike Beasley, Favio Faifer +6
We present recent results from our long-term Gemini/GMOS study of globular clusters in early-type galaxies. To date, we have obtained photometry and spectroscopy for clusters in NG…
Influence of Black Holes on Stellar Orbits
Karl Gebhardt
We review the current state of dynamical modeling for galaxies in terms of being able to measure both the central black hole mass and stellar orbital structure. Both of these must…
Spectroscopy of Globular Clusters in NGC 1399 - A Progress Report
T. Richtler, B. Dirsch, D. Geisler +9
We performed spectroscopy of globular clusters associated with NGC 1399 and measured radial velocities of more than 400 clusters, the largest sample ever obtained for dynamical stu…
Obtaining Galaxy Masses Using Stellar Absorption and [O II] Emission-Line Diagnostics in Late-Type Galaxies
Chip Kobulnicky, Karl Gebhardt
The [O II] lambda3727 emission lines and absorption features from stellar Balmer and Ca H&K lines are the most accessible kinematic diagnotics in galaxies at z~1. We investigate th…
The Quadruple Gravitational Lens PG1115+080: Time Delays and Models
P. L. Schechter, C. D. Bailyn, R. Barr +24
Optical photometry is presented for the quadruple gravitational lens PG1115+080. A preliminary reduction of data taken from November 1995 to June 1996 gives component ``C'' leading…
