Description
If dark matter particles were relativistic deeply within the
radiation-dominated epoch ("warm" dark matter), the formation of
structures would be altered at scales below their "free-streaming horizon"
as compared to the standard Lambda-CDM concordance model. Such
modifications would results in the reduced abundance of structures at
galactic scales and below. In this talk I will overview properties of warm
dark matter candidates, their signatures and observational probes of warm
dark matter paradigm.
