N-body Simulation - Incorporating Baryons, Leptons and Photons Into Simulations

Incorporating Baryons, Leptons and Photons Into Simulations

Many simulations simulate only cold dark matter, and thus include only the gravitational force. Incorporating baryons, leptons and photons into the simulations dramatically increases their complexity and often radical simplifications of the underlying physics must be made. However, this is an extremely important area and many modern simulations are now trying to understand processes that occur during galaxy formation which could account for galaxy bias.
