"Simulating the large-scale baryonic Universe"

Bottom panel shows the gas density (blue) and temperature (red) in the large-scale Horizon-AGN simulation.

The tow top panels are zoomed-in view around a large-scale (~10 Mpc) filament simulated either without (left) or with (right) feedback from supermassive black holes (the so-called Active Galactic Nuclei, AGN).

AGN powers massive outflows from galaxies and heat up cosmic gas up to ~Mpc scales.
