The Black Hole Mass and Photometric Components of NGC 4826 Open
We present infrared photometry and Hubble Space Telescope imaging and spectroscopy of the Sab galaxy NGC 4826. Schwarzschild dynamical modeling is used to measure its central black hole mass M . Photometric decomposition is used to enable …

The Black Hole Mass and Photometric Components of NGC 4826 Open
We present IR photometry and HST imaging and spectroscopy of Sab galaxy NGC 4826. Schwarzschild dynamical modeling is used to measure its central black hole mass $M$. Photometric decomposition is used to enable a comparison of $M$ to publi…

Orbit-based dynamical models of the Sombrero Galaxy (NGC 4594) Open
We present axisymmetric, orbit-based models to study the central black hole (BH), stellar mass-to-light ratio (M/L), and dark matter (DM) halo of NGC4594 (M104, the Sombrero Galaxy). For stellar kinematics, we use published high-resolution…

A 5 × 10<sup>9</sup> M<sub>⊙</sub> BLACK HOLE IN NGC 1277 FROM ADAPTIVE OPTICS SPECTROSCOPY Open
The nearby lenticular galaxy NGC 1277 is thought to host one of the largest black holes known, however the black hole mass measurement is based on low spatial resolution spectroscopy. In this paper, we present Gemini Near-infrared Integral…

A Quintet Of Black Hole Mass Determinations Open
We report five new measurements of central black hole masses based on Space Telescope Imaging Spectrograph and Wide Field Planetary Camera 2 observations with the Hubble Space Telescope (HST) and on axisymmetric, three-integral, Schwarzsch…
