3D evolution of HI and ionizing radiation
Volume rendering of the HI fraction (left) and ionizing radiation field (right) in the Thesan-1 simulation. The top and bottom plots show the time evolution of these quantities, with the moving circle
representing the time shown in the renderings.

3D evolution of ionization fronts (360° video)
3D rendering of the evolution of reionization fronts in Thesan-1. Reionization fronts are defined as regions having an ionized fraction of 0.5 after being smoothed with a top-hat kernel of size approximately 0.5 Mpc.

Ionization fronts evolution in Thesan models
3D rendering of the evolution of reionization fronts in different simulations from the Thesan suite. Reionization fronts are defined as regions having an ionized fraction of 0.5 after being smoothed with a top-hat kernel of size approximately 0.5 Mpc.

Evolution of gas and radiation in Thesan
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.

3D evolution of ionization fronts (flythrough)
3D rendering of the evolution of reionization fronts in Thesan-1. Reionization fronts are defined as regions having an ionized fraction of 0.5 after being smoothed with a top-hat kernel of size approximately 0.5 Mpc.

3D internal evolution of gas and radiation
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.
