Abstract

Cosmological hydrodynamical simulations of galaxy formation are a powerful theoretical tool, and enable us to directly calculate the observable signatures resulting from the complex process of cosmic structure formation. Here we present early results from the ongoing TNG50 run, an unprecedented ‘next generation’ cosmological, magnetohydrodynamical simulation—the third and final volume of the IllustrisTNG project, with over 20 billion resolution elements and capturing spatial scales of \(\sim \)100 parsecs. It incorporates the comprehensive TNG model for galaxy formation physics, and we here describe the simulation scope, novel achievements, and early investigations on resolved galactic and halo structural properties.

We also keep fixed all the relevant physical and numerical parameters when varying the numerical resolution, an approach not always adopted in computational galaxy formation. This allows us to establish a well-posed numerical problem towards which we can demonstrate convergence.
