Jeans Anisotropic Modelling (JAM) of Galactic Dynamics
Usage examples in Jupyter Notebook for the Jeans Anisotropic Modelling JAM method, originally described for cylindrically aligned velocity ellipsoids in Cappellari (2008) and for a spherically aligned velocity ellipsoid in Cappellari (2020).
The Jeans Anisotropic Modelling (JAM) method models the stellar kinematics of galaxies to determine their intrinsic structure and mass distribution. It solves the Jeans equations of stellar hydrodynamics for a spherical or axisymmetric stellar system.
One can run the Jupyter notebooks without installing anything by clicking on the binder button above. Just note that the code will run much faster on your local computer.
