Description
Structure formation in WDM scenarios is qualitatively different from CDM. The free streaming of WDM particle candidates (e.g. sterile neutrinos) is damping the fluctuation spectrum, flattening the mass function of halos and imprinting a phase space density limit for dark matter structures. Using N-body simulations, we explore these effects on structure formation on both large scales and small scales (internal structure of halos), where CDM model is challenged.
