Three-dimensional Keplerian orbit-superposition models of the nucleus of M31
We present three-dimensional eccentric disc models of the nucleus of M31, modelling the disc as a linear combination of thick rings of massless stars orbiting in the potential of a central black hole. Our models are nonparametric generalisations of the parametric models of Peiris and Tremaine. The m...
