Completely analytical families of anisotropic gamma-models
Pieter Buyle, Chris Hunter, Herwig Dejonghe
We present new analytical distribution functions for anisotropic spherical galaxies. They have the density profiles of the gamma-models, which allow a wide range of central density…
Jeans solutions for triaxial galaxies
Glenn van de Ven, Chris Hunter, Ellen Verolme +1
The Jeans equations relate the second-order velocity moments to the density and potential of a stellar system. For general three-dimensional stellar systems, there are three equati…
Lensing Properties of Cored Galaxy Models
N. W. Evans, C. Hunter
A method is developed to evaluate the magnifications of the images of galaxies with lensing potentials stratified on similar concentric ellipses. A simple contour integral is provi…
Lensing Properties of Scale-Free Galaxies
C. Hunter, N. W. Evans
The multiple images of lensed quasars provide evidence on the mass distribution of the lensing galaxy. The lensing invariants are constructed from the positions of the images, thei…
Axisymmetric galaxy models wth central BHs, with an application to M32
E. E. Qian, P. T. de Zeeuw, R. P. van der Marel +1
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 cla…
