Abstract

IllustrisTNG (www.tng-project.org) is a series of three cosmological gravity+magnetohydrodynamics simulations for galaxy physics spanning cosmological volumes of 50, 100, and 300 Mpc a side, respectively. They return a synthetic sample of thousands of well-resolved galaxies across cosmic times and environments. I will give an overview of the insights that these simulations are allowing us to uncover on the evolution of the galaxy populations and of the galaxies' inner properties, from the stellar mass assembly of the most massive brightest cluster galaxies at recent times to the evolution of the star formation activity of galaxies from high redshift to today, in isolation or as satellites. In particular, I will focus on the outcome of the final run of the series, TNG50, a cosmological volume at zoom resolution. TNG50 is allowing to reveal, for example, the quantitative details of gas outflows and their relation to galaxy properties as well as to follow the emergence of stellar and gaseous disks across cosmic times.
