Description
The dynamical state of the Milky Way's stellar disk can be represented by a phase space distribution function (DF), which gives the density of stars in terms of position and velocity. Using the DF, the gravitational potential can be estimated, and subsequently the dark matter content. I will describe a machine learning algorithm based on mixture models to determine the DF and gravitational potential from observational surveys such as Gaia DR3.
