Most of these movies were made in collaboration with the named person. They can be downloaded and used for any educational purpose. Please give appropriate credit - thanks! The best Linux player I have found is mtv. Older versions of Windows media player may not play some of the larger movies. Warning - some of these movies are very large. Most were made with Joachim Stadel's PKDGRAV code and TISPY.

Jürg Diemand: vl_form_z12....
The hierarchical formation of the dark matter halo that might surround our own Milky Way. Structures start forming a few million years after the big bang and grown ever larger through violent merging and accretion. What you see orbiting within our final galactic halo are the remnants of this merging hierarchy that have yet to be observed

John Dubinski: tflops
The future of our Galaxy. In a few billion years our neighbour the Andromeda galaxy will collide with the Milky Way. We can calculate this evolution and future using supercomputer simulations. The final outcome is a new elliptical galaxy

Oscar Agertz: magstream2
This ghostly cloud is suffering hydrodynamical drag as it moves within our Galactic halo. The turbulence and disruption process can be simulated with an adaptive mesh hydrodynamics code.

Sinziana Paduroiu: qqq.avi
We don't know the nature of most of the mass in the universe. This movie shows the formation of cosmic structures in a Universe dominated by warm dark matter. The top down formation of structures is very different from the above hierarchical CDM movle.

Sinziana Paduroiu: qq.avi
A close up view of the formation of a warm dark matter filament

Oscar Agertz: coolhalo.x.
How do molecular clouds and stars form? This movie shows the accretion of gas into the disk of a galaxy and the resulting turbulence and molecular cloud formation and evolution

Oscar Agertz: coolhalo.star.x
This movie shows the stars that form within the molecular clouds from the above movie

Chris Mihos: Cartwheelfull
A collision between two galaxies of different masses can create spectacular new galaxies, like the Cartwheel galaxy, which evolve into giant low surface brightness galaxies
