Description

Heavy dark matter can be created by a first order phase transition and match the observation even for masses much larger than expected by the GK bound on WIMP. In the case of suppressed interactions with the thermal bath the DM might display free-streaming, leading to the possibility of having simultaneously warm and heavy DM. In this talk I extend the previous discussion to the case of fermion and gauge DM. The latter in particular is more secluded but will yield large abundances for ultra-relativistic bubble walls.
