Most of the supermassive black hole mass (M • ) estimates based on stellar kinematics use the assumption that galaxies are axisymmetric oblate spheroids or spherical. Here, we use fully general triaxial orbit-based models to explore the effect of relaxing the axisymmetric assumption on the previously studied galaxies M32 and NGC 3379. We find that M32 can only be modelled accurately using an axisymmetric shape viewed nearly edge-on, and our black hole mass estimate is identical to previous…

Dynamical Modeling of Galaxies and Supermassive Black Holes: Axisymmetry in Triaxial Schwarzschild Orbit Superposition Models
We present a detailed analysis of the behavior of the triaxial Schwarzschild orbit superposition method near the axisymmetric limit. Orbit superposition modeling is the primary method used to
Triaxial models of massive elliptical galaxies
Massive triaxial early-type galaxies sit at the end of galaxy evolution and account for almost one third of the most luminous galaxies in the local Universe. They presumably host the highest mass
The Black Hole in the Most Massive Ultracompact Dwarf Galaxy M59-UCD3
We examine the internal properties of the most massive ultracompact dwarf galaxy (UCD), M59-UCD3, by combining adaptive optics assisted near-IR integral field spectroscopy from Gemini/NIFS, and
The Effect of Spatial Gradients in Stellar Mass-to-light Ratio on Black Hole Mass Measurements
We have tested the effect of spatial gradients in stellar mass-to-light ratio () on measurements of black hole masses (M •) derived from stellar orbit superposition models. Such models construct a
Two channels of supermassive black hole growth as seen on the galaxies mass–size plane
We investigate the variation of black hole masses (Mbh) as a function of their host galaxy stellar mass (Mstar) and half-light radius (Re). We confirm that the scatter in Mbh within this plane is
A black hole mass determination for the compact galaxy Mrk 1216
Mrk 1216 is a nearby, early-type galaxy with a small effective radius of 2.8 kpc and a large stellar velocity dispersion of 308 km/s for its K-band luminosity of 1.4x10^11 L_sun. Using integral-field
An over-massive black hole in the compact lenticular galaxy NGC 1277
Observations of the stellar kinematics of NGC 1277, which is a compact, lenticular galaxy, determine that the mass of the central black hole is 1.7 × 1010 solar masses, or 59 per cent of its bulge mass, and show observations of five other compact galaxies that have properties similar to NGC-1277 and therefore may also contain over-massive black holes.
Stellar dynamical modeling is a powerful method to determine the mass of black holes in quiescent galaxies. However, in previous work the presence of a dark matter halo has been ignored in the
The M87 Black Hole Mass From Gas-Dynamical Models Of Space Telescope Imaging Spectrograph Observations
The supermassive black hole of M87 is one of the most massive black holes known and has been the subject of several stellar and gas-dynamical mass measurements; however, the most recent revision to
Depleted Galaxy Cores and Dynamical Black Hole Masses
Shallow cores in bright, massive galaxies are commonly thought to be the result of scouring of stars by mergers of binary supermassive black holes. Past investigations have suggested correlations
