Description
We point out that dark matter which is produced non-adiabatically in a supercooled phase transition receives a boost in velocity which leads to long free-streaming lengths. We find that this could be observed via the suppressed matter power spectrum for dark ma er masses around ∼ 10^8 − 10^9 GeV. We thus offer novel physics goals for galaxy surveys, Lyman-α, and weak lensing observations, and connect these to the gravitational waves from such phase transitions.
