Anisotropic distribution functions for spherical galaxies
Zhenglu Jiang, Leonid Ossipkov
A method is presented for finding anisotropic distribution functions for stellar systems with known, spherically symmetric, densities, which depends only on the two classical integ…
Dynamical modelling of the elliptical galaxy NGC 2974
Zhenglu Jiang
In this paper we analyse the relations between a previously described oblate Jaffe model for an ellipsoidal galaxy and the observed quantities for NGC 2974, and obtain the length a…
General Flattened Jaffe Models for Galaxies
Zhenglu Jiang, Daoyuan Fang, Hongxia Liu +1
In this paper we extend oblate and prolate Jaffe models into more general flattened Jaffe models. Since dynamical properties of oblate and prolate Jaffe Models have been studied by…
Axisymmetric models for galaxies by equipotential and equidensity methods
Zhenglu Jiang, Daoyuan Fang, David Moss
In this paper we outline equipotential and equidensity methods of constructing axisymmetric models for galaxies. The former method defines equipotentials, from which the correspond…
Two-integral distribution functions for axisymmetric stellar systems with separable densities
Zhenglu Jiang, Leonid Ossipkov
We show different expressions of distribution functions (DFs) which depend only on the two classical integrals of the energy and the magnitude of the angular momentum with respect…
