Query: Thermally modified sterile neutrino portal dark matter and gravitational
  waves from phase transition: The Freeze-in case   We consider the thermal effects into the evaluation of the dark matter
production process. With the assistance of the right handed neutrinos, the
freeze-in massive particle dark matter production history can be modified by
the two-step phase transitions. The kinematic of decay/inverse decay or
annihilation processes can be affected by the finite temperature effects as the
Universe cools down. The history of the symmetry respected by the model can be
revealed by the DM relic abundance evolution processes. The strong first order
electroweak phase transition generated gravitational waves can be probed. The
number of extra scalars for the Hierarchy problem can be probed through the
Higgs off-shell searches at the LHC.
