The purple cosmic web of gas feeds intense star formation in the first galaxies. As stars live and die, they produce oxygen (yellow) and photons (white), all self-consistently evolved and tracked together by the new Megatron simulations.
New MEGATRON simulations connect the first stars and dwarf galaxies, showing how ancient explosions may explain the iron patterns astronomers observe today.
