Kinematics and Dynamics of the Galactic Bulge through Planetary Nebulae

The discovery of $∼$500 planetary nebulae (PNe) in the bulge region allows us to probe the bulge out to $∼8$ kpc. This opens up the possibility to track bulge-disc interactions to unprecedented details. We present an exploration of bulge dynamics with Nbody models of a triaxial bulge embedded in an exponential disc (Peyaud 2005).
