The IllustrisTNG project is an ongoing series of large, cosmological magnetohydrodynamical simulations of galaxy formation. TNG aims to illuminate the physical processes that drive galaxy formation: to understand when and how galaxies evolve into the structures that are observed in the night sky, and to make predictions for current and future observational programs. The simulations use a state of the art numerical code which includes a comprehensive physical model and runs on some of the largest supercomputers in the world. TNG is a successor to the original Illustris simulation and builds on several years of effort by many people. The project description page contains an introduction to the motivations, techniques, and early science results of the TNG simulations. Presently, the project includes three primary runs spanning a range of volume and resolution; these are called TNG50, TNG100, and TNG300.
