The Evolution of Galaxies in Cosmological
Simulations. This movie was shown at
the ETH Zürich Exhibition in the International Year
of Astronomy 2009. [117 MB] |
|
This movie shows how a galaxy group grows over
cosmic history. The color channels
correspond to BRI filter bands and are approximately what
one would see with his/her own eyes. [1.4 MB] |

heavily distorted by a satellite galaxy (run with the SPH
& N-body code GASOLINE). |

| Redshift z~0.5. The age of the Universe is 8
billion years. |
A few hundred million years later. An elliptical
satellite approaches the disk galaxy. |
3 million years later. The disk is heavily
damaged. |
8 million years later. The disk is partially
restored. |
| False color images of
the intergalactic gas in a cosmological simulation of
a galaxy group.
The simulations have been run with the AMR code RAMSES. |

I created these
movies and images with the help of GIMP, the ImageMagick
suite and mencoder. Thanks folks for developing and
maintaining these great software tools!
