Here are some renderings of 21cm simulations with different views of the evolution of primordial hydrogen in the early universe (at about 500My after the big bang).

3D flythrough. You’ll need red blue glasses.

The movies are made by using output from a reionization simulation (21cmfast) and then rendered in Blender. Rendering heavy lifting was done by SESE Visualization Specialist Reid Landeen with help from the Marston Theater team Jacob Burba, Tyler Cox, Cameron White and MET director Ric Ailling.


The construction of the NRAO 140ft dish was a truly awesome feat of scientific engineering. A documentary was made. Heres a cut down to the good parts. The full thing is here.


PAPER data as sound.  For the afficionados we are playing a each baseline’s raveled out waterfall spectrum. The tones you here are bright sources which have a sinusoidal fringe spectrum; your ear is doing a delay transform!
