« New methods for Galaxy modelling »

A series of massive surveys, including SDSS, SEGUE, RAVE, Pan Starrs, Hermes and Gaia, are enormously increasing the wealth of data for the Milky Way. We hope to use these data to map the distribution of dark matter and to deduce the history of our very typical Galaxy. This programme requires dynamical models that far surpass what is currently available in flexibility and sophistication. A discussion of our modelling requirements will be followed by an introduction to the torus modelling technique. This development of Schwarzschild modelling, in which orbits become geometrical structures in phase space rather than time series of phase-space points, promises to satisfy our modelling requirements.
