The contour integral method of Hunter & Qian is applied to axisymmetric galaxy models in which the distribution function (DF) is of the form f=f(E,L_z), where E and L_z are the classical integrals of motion in an axisymmetric potential. A practical way to construct the unique even part of the DF for such systems is presented. It is applied to models, both oblate and prolate, in which the mass density is stratified on similar concentric spheroids. The spheroids with scale-free densities are…

Axisymmetric Three-Integral Models for Galaxies
We describe an improved, practical method for constructing galaxy models that match an arbitrary set of observational constraints, without prior assumptions about the phase-space distribution
Two-integral distribution functions in axisymmetric galaxies: Implications for dark matter searches
We address the problem of reconstructing the phase-space distribution function for an extended collisionless system, with known density profile and in equilibrium within an axisymmetric gravitational
Dynamical Stability of N-Body Models for M32 with a Central Black Hole
We study the stability of stellar dynamical equilibrium models for M32. Kinematic observations show that M32 has a central dark mass of ~3 × 106 M☉, most likely a black hole, and a phase-space
Flattened Jaffe models for galaxies
This paper introduces a class of galactic models which extend Jaffe's spherical models to axisymmetric systems, and then studies the properties of their densities and two-integral even distribution
Two-integral Schwarzschild models
We describe a practical method for constructing axisymmetric two-integral galaxy models [with distribution functions of the form f(E, L z ), in which E is the orbital energy, and L z is the vertical
The dynamical structure of isotropic spherical galaxies with a central black hole
We discuss the kinematical structure of a two-parameter family of isotropic models with a central black hole. The family contains the slope of the central density cusp and the relative black hole
Improved Evidence for a Black Hole in M32 from HST/FOS Spectra. II. Axisymmetric Dynamical Models
Axisymmetric dynamical models are constructed for the E3 galaxy M32 to interpret high spatial resolution stellar kinematical data obtained with the Hubble Space Telescope (HST). Models are studied
Building Galaxy Models with Schwarzschild Method and Spectral Dynamics
Tremendous progress has been made recently in modelling the morphology and kinematics of centers of galaxies. Increasingly realistic models are built for central bar, bulge, nucleus and black hole of
Dynamical models of ngc 3115
We present new dynamical models of the S0 galaxy N3115, making use of the available published photometry and kinematics as well as two-dimensional TIGER spectrography. The models are based on
Shear and ellipticity in gravitational lenses
Galaxies modeled as singular isothermal ellipsoids with an axis ratio distribution similar to the observed axis ratio distribution of E and S0 galaxies are statistically consistent with both the
