Title: When Old Meets New:  Mixing Between Our Galaxy and Infalling Clouds

Abstract:

Our Galaxy is not alone.   It is surrounded by a gaggle of smaller galaxies and by enormous clouds of gas.    Just as some of the smaller galaxies orbit into and merge with the Milky Way, it appears that some of the clouds are also colliding with and merging into the Milky Way.    The collisions are hydrodynamic and magnetohydrodynamic in nature, in that they involve the flow and mixing of fluids.   My group has been simulating the mixing, with the aid of high performance computer systems.    I will present our simulational results and show how they compare with observations of the clouds.
