Fly through: Volume rendering of the neutral hydrogen gas density overlaid with a transparency mask to visualize regions with significant ionizing radiation in the Thesan simulation. The movie shows the patchy ionization structure of the intergalactic medium before the completion of reionization. By the end of the movie only self-shielded high-density filaments remain unionized.

Volume rendering of the gas density overlaid with a transparency mask to only visualize regions with significant ionizing radiation in the Thesan-1 simulation. The initial flickering highlights the burstiness of radiation output from low mass galaxies. As reionization progresses the radiation field permeates throughout the Universe and gradually reveals the complex large-scale cosmic structure.
