The Effect of Thermal Velocities on Structure Formation in N-body Simulations of Warm Dark Matter

23 Jun 2017 Matteo Leo Carlton M. Baugh Baojiu Li Silvia Pascoli

We investigate the impact of thermal velocities in N-body simulations of structure formation in warm dark matter models. Adopting the commonly used approach of adding thermal velocities, randomly selected from a Fermi-Dirac distribution, to the gravitationally-induced velocities of the simulation particles, we compare the matter and velocity power spectra measured from CDM and WDM simulations, in the latter case with and without thermal velocities...
