Scientific paper

We show that self-consistent, triaxial models for galactic nuclei containing supermassive black holes can be constructed. We first use Schwarzschild's method to find families of orbits that reproduce an assumed power-law mass distribution around a central point mass; the model axis ratios are 1.0 : 0.79 : 0.5 and we consider density laws of ρ ~ r-γ with γ =1,2. The models are found to be supported mostly by tube orbits. We then generate Monte-Carlo sets of initial conditions and integrate them forward in time using an N-body code. The models evolve only slightly and maintain their triaxial shapes. We discuss the observable properties of the models.
