Description
It has recently become possible to numerically simulate large, representative volumes of the Universe. These cosmological (magneto)hydrodynamical simulations solve for the coupled evolution of gas, dark matter, stars, and supermassive black holes interacting via the coupled equations of self-gravity and fluid dynamics, all within the context of an expanding spacetime.
The IllustrisTNG simulations exemplify the current state-of-the-art in this context. They simultaneously resolve tens of thousands, to millions, of individual galaxies - with properties and characteristics in broad agreement with observational data of real galaxy populations. This enables many theoretical studies on galaxy formation and evolution, as well as large-scale structure and cosmology.
I will give a tour of the TNG simulations, touching on a few scientific applications and novel insights. I will showcase the information content and breadth of a virtual Universe, and describe our efforts to publicly release these large datasets through a powerful, online science platform (www.tng-project.org) that is democratizing access to cosmological simulations and paving the way for Open Science and Open Data in theoretical astrophysics.
