Illustris TNG is a theoretical astrophysics project that created the most detailed simulation of the universe to date, and it turns out that black holes influence the distribution of dark matter.
Via the project page:
Every galaxy harbours a supermassive black hole at its center. A new computer model now shows how these gravity monsters influence the large-scale structure of our universe. The research team includes scientists from the Heidelberg Institute for Theoretical Studies (HITS), Heidelberg University, the Max-Planck-Institutes for Astronomy (MPIA, Heidelberg) and for Astrophysics (MPA, Garching), US universities Harvard and the Massachusetts Institute of Technology (MIT), as well as the Center for Computational Astrophysics in New York. The project, "Illustris–The Next Generation" (IllustrisTNG) is the most complete simulation of its kind to date. Based on the basic laws of physics, the simulation shows how our cosmos evolved since the Big Bang. Adding to the predecessor Illustris project, IllustrisTNG includes some of the physical processes which play a crucial role in this evolution for the very first time in such an extensive simulation.
