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.

Volume rendering of the neutral hydrogen gas density overlaid with a transparency mask to only visualize regions with significant ionizing radiation in the Thesan-1 simulation. This view 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.
