The above movies show the evolution of projected distribution of
mass-weighted gas temperature, gas mass, and dark matter mass
in a comoving 50x50x10 Mpc/h slice. The above is the same slice as the one
shown in the paper.
The clock shows from left to right, the snapshot number, scale-factor, redshift, and the cosmic time in units of the current Hubble time tH=14 Gyr (for h=0.7). The reionization takes place at z=6 in this simulation. As we showed in Nagamine & Loeb (2003, New Astronomy, 8, 439), the dark matter mass distribution hardly evolves after t/tH=3.0. You'll see that the temperature quickly decreases after t/tH=3.0 due to the exponential expansion of the universe.
The clock and the pictures may not synchronize well depending on your download speed. The movies tend to get behind of the clock by 1-2 frames if your download speed is slow. The temperature movie goes all green suddenly at z=6, so you'll know when you're out of sync. I've disabled the looping of the movie to avoid accumulating the sync. If you're out of sync, wait for the first movie to finish, and click `Reload' or `Refresh' to see it from the beginning again. (But I've found that they sometimes don't behave as I wanted to. For example, the Netscape on my Mac laptop doesn't bother to reload the movies when I click `Reload'. The results are perhaps browser dependent, and IE seems to work well.)
