We construct dynamical models for a sample of 36 nearby galaxies with Hubble Space Telescope (HST) photometry and ground-based kinematics. The models assume that each galaxy is axisymmetric, with a two-integral distribution function, arbitrary inclination angle, a position-independent stellar mass-to-light ratio , and a central massive dark object (MDO) of arbitrary mass M•. They provide acceptable fits to 32 of the galaxies for some value of M• and ; the four galaxies that cannot be fitted… Expand
Axisymmetric Dynamical Models of the Central Regions of Galaxies
We present axisymmetric, orbit superposition models for 12 galaxies using data taken with the Hubble Space Telescope (HST) and ground-based observatories. In each galaxy, we detect a central blackExpand

ABSTRACT In this work we build a detailed dynamic model for a S0 galaxy possibly hostinga central massive dark object (MDO). We show that the photometric profiles and thekinematics along the major andExpand

An over-massive black hole in the compact lenticular galaxy NGC 1277
TLDR
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.
