This movie shows the
formation of the stellar halo Aq-F-2 from the
Aquarius series. Time runs from redshift z~4 to
z=0. At z=0, the stellar halo is dominated by a spectacular shell system.
The camera points towards its centre of
the main galactic halo all times. The brightness of
particles corresponds to their projected
density, and their colour to their velocity
dispersion. |

You also need the right software. You can use the 'mplayer' program under Linux. On Windows you can use Windows Media Player and on a Mac Quicktime should work. |
This movie shows the
formation of another stellar halo, Aq-A-2, from
the Aquarius series. This halo assembles most
of its mass much earlier than Aq-F-2 and has a
quieter growth history. It contains several
prominent streams and is likely to be a closer
analogue of the Milky Way or M31 haloes than
Aq-F-2. |
