Description

We investigate a scenario in which the dark matter is produced via freeze-in with contributions from both the UV and IR. We also take into account an additional production mode from the decay of the inflaton. We analyze the parameter space at the level of the dark matter phase space distribution to assess potential impact of a non-thermal distribution, including bounds from Lyman-$\alpha$ measurements.
