Uncovering a Cosmic Matter Reservoir
Uncovering promising evidence that may reveal the location of the missing baryonic matter in the universe.
Baryonification – Dark matter N-body simulations and the impact of gas-trophysics
The effects of gas are complicated and challenging to simulate. Today’s paper explores a way to account for gas in cosmological simulations without actually including it!
