Large-scale model of the Milky Way: Stellar kinematics and the microlensing event timescale distribution in the Galactic bulge

We build a stellar-dynamical model of the Milky Way's barred bulge and disk, using a newly implemented adaptive particle method. The underlying mass model has been previously shown to match the Galactic near-infrared surface brightness as well as gas-kinematic observations. Here we show that the new stellar-dynamical model also matches the observed stellar kinematics in several bulge fields and that its distribution of microlensing event timescales reproduces the observed timescale distribution of the MACHO experiment with a reasonable stellar mass function. The model is therefore an excellent basis for further studies of the Milky Way. We also predict the observational consequences of this mass function for parallax shifted events.
