Reionization movie page
The following movies have been produced either from full-fleshed
radiative transfer simulations or from semi-analytic schemes based on
the excursion-set formalism. It may be good to load the movies into
cache first and then start over, for smooth viewing:
Flying through the reionizing universe
This a flight through a 500Mpc/h box, viewing 21cm brightness temperature,
from z=16 to 11. One case with recombinations a la Miralda-Escude
(2000), in the other without. x_i is changing from roughly 0.1 to 1.0
during the movie. A constant color gradient makes evident that
overdense (red) regions are over time consumed by bubbles in dark blue
coloring. z_av(box=14.0, zeta=60. Resolution 512^3. Smoothing about 2
pixels. There's a .ps file in the same folder showing a sideways cut
through the simulation box.
without recombinations
with recombinations
Comparison of radiative transfer simulations and simple analytic
models. Box is 65.6Mpc/h, resolution
256^3. Smoothed corresponding to about an arcmin on the sky.
Movie
This shows HII regions expanding with time, the redshift is 8, timing is such that 10^7 years pass per second of showing
time. Sidelength 100 Mpc/h. zeta=10. Resolution 128^3, smoothed down to two
arcminutes. anim1-4 are just different cuts through the simulation
boxes.
