Two ten-billion-solar-mass black holes at the centres of giant elliptical galaxies
Nicholas J. McConnell, Chung-Pei Ma, Karl Gebhardt +5
Observational work conducted over the last few decades indicates that all massive galaxies have supermassive black holes at their centres. Although the luminosities and brightness…
The central dark matter distribution of NGC 2976
Joshua J. Adams, Karl Gebhardt, Guillermo A. Blanc +5
We study the mass distribution in the late-type dwarf galaxy NGC 2976 through stellar kinematics obtained with the VIRUS-P integral-field spectrograph and anisotropic Jeans models…
Galaxy Kinematics with VIRUS-P: The Dark Matter Halo of M87
Jeremy D. Murphy, Karl Gebhardt, Joshua J. Adams
We present 2-D stellar kinematics of M87 out to R = 238" taken with the integral field spectrograph VIRUS-P. We run a large set of axisymmetric, orbit-based dynamical models and fi…
The Black-Hole Mass in M87 from Gemini/NIFS Adaptive Optics Observations
Karl Gebhardt, Joshua Adams, Douglas Richstone +5
We present the stellar kinematics in the central 2" of the luminous elliptical galaxy M87 (NGC 4486), using laser adaptive optics to feed the Gemini telescope integral-field spectr…
