Galactic Chemical Dynamics

We are developing multidimensional computer simulations of the origin and evolution of galaxies. These include hydrodynamic simulations of various gas components and N-body simulations of the stellar populations. These simulations are being used to study various galaxy formation and evolution scenarios. We also study galactic abundance gradients and constraints on the history of star formation and the stellar initial mass function. and the origin of globular clusters.
