New #AstroPhysicsFactlet related to the numerical simulation of #feedback from active galactic nuclei and star formation in the simulations we used to produce hypothetic histories of our Universe. The specific outcome of feedback affects our predictions of the amount of metals and magnetic fields in the universe outside of galaxies, the fate of “missing baryons” that have escaped massive halos across cosmic history, and much more. #astronomy #astronomy https://files.mastodon.social/media_attachments/files/111/154/300/744/055/953/original/1be55b36f2e6aeff.png
