1. distribution of mass-weighted ionization fraction
: ionization fraction is 1 for red, about 0.5 for green, and 0 for blue.

- 25 Mpc/h subvolume : slide (download slide files) or mpeg
- 50 Mpc/h subvolume : slide (download slide files) or mpeg
- 100 Mpc/h : slide (download slide files) or mpeg (fast but small size) mpeg (slow but large size)

2. distribution of matter density and ionization fraction
: one slice of a simulation box. (shade region = neutral, red = high density)
- 100 Mpc/h : slide or mpeg

3. power spectrum of ionized hydrogen density, neutral hydrogen density,
and matter density

: blue = ionized hydrogen, red = neutral hydrogen, solid black = matter,
dash black = sum of ionized hydrogen power spectrum and neutral hydrogen power spectrum
