SUMMARY:Supercomputer Simulations of the Universe: Interfacing galaxy 
 formation with precision cosmology\, Astronomy Colloquium\, Volker Spr
 ingel\, Max-Planck Institute for Astrophysics
DESCRIPTION:Numerical simulations of cosmic structure formation have b
 ecome a powerful tool in astrophysics. Starting right after the Big Ba
 ng\, they predict the dark matter backbone of the cosmic web far into 
 the non-linear regime and follow complex galaxy formation physics with
  rapidly improving fidelity. In my talk\, I will review the methodolog
 y and selected results of recent hydrodynamical galaxy formation simul
 ations\, such as the IllustrisTNG MillenniumTNG projects. In particula
 r I will discuss some of the primary challenges in modelling strong\, 
 scale-dependent feedback processes that regulate star formation\, and 
 highlight the important role played by supermassive black holes in gal
 axy formation. I will also discuss extremely large simulations and des
 cribe how they help to make reliable predictions for the impact of bar
 yons and massive neutrinos on cosmological observables\, effects that 
 need to be understood to make full use of upcoming new survey data.
