Query: Gravitational wave signals of dark matter freeze-out   We study the stochastic background of gravitational waves which accompany the
sudden freeze-out of dark matter triggered by a cosmological first order phase
transition that endows dark matter with mass. We consider models that produce
the measured dark matter relic abundance via (1) bubble filtering, and (2)
inflation and reheating, and show that gravitational waves from these
mechanisms are detectable at future interferometers.
