How black holes shape the cosmos

Astrophysicists from Heidelberg, Garching, and the USA gained new insights into the formation and evolution of galaxies. They calculated how black holes influence the distribution of dark matter, how heavy elements are produced and distributed throughout the cosmos, and where magnetic fields originate. This was possible by developing and programming a new simulation model for the universe, which created the most extensive simulations of this kind to date. First results of the “IllustrisTNG” project have now been published in three articles in the journal Monthly Notices of the Royal Astronomical Society. These findings should help to answer fundamental questions in cosmology.
