Simulation Visualizations

Simulation Visualizations

I have generated a number of nice structure formation movies from our simulations. This page contains all the structure formation movies I generated for the OWLS project (Schaye et al. 2010). My other movies, inluding other types of OWLS movies and older visualizations are on my Other Movies page. Feel free to use any of these movies in talks and the like. If you see something in one of the movies that raises any questions, or would like any additional information then feel free to email me.

If you have issues with playback, I recommend downloading VLC (Mac, Windows, Linux) or Perian (Mac).

Simulations of the Milky Way

These movies show a face-on view of a simulated Milky Way type galaxy. The colours show the gas density. The movies run for a total of 2 Gyr, and are relatively high resolution (800x800 pixels). I generally use these on the first page of a presentation to make the titles more interesting and accordingly have provided two versions: one with a black background and one in white.

The OWLS 25 Mpc/h Region

A Slice From The Entire Volume

A slice through the 25Mpc/h OWLS simulation. The slice is 1Mpc/h thick and the movie runs from a redshift of 20 down to redshift two.

A slice through the 25Mpc/h OWLS simulation. The slice is 2Mpc/h thick and the movie runs from a redshift of 20 down to redshift zero. The video to the left shows density, other available projections: A video combining all projections is here:

Group Galaxies

These movies correspond to a region with a comoving size of 3Mpc/h. By redshift zero the main object in this volume will become a halo of mass 1014 M sun, this movie stops at redshift 2. Click each section for the movies.

The image to the left links to a move showing all of the density, temperature, metallicity and stellar distribution. The links below go to the individual movies

The OWLS 100 Mpc/h Volume

The Formation of a Galaxy Cluster

This movie shows the formation of a cluster of galaxies down to redshift zero. The two panels show density and metallicity. This movie was encoded using a different encoder than most of the others on this page. If you cannot get it to play you may need to install the XViD codec, or can download the .mpg file
