Description
The next generation of gravitational wave (GW) detectors open up a new window to probe
physics beyond the Standard Model in the early universe. An intriguing possibility are
first order phase transition in a dark sector giving rise to a stochastic GW background.
In this talk I will discuss GW signals from a dark sector with a spontaneously broken
gauge symmetry and a stable dark fermion. Requiring the observed relic abundance of dark
matter constrains the GW signal frequency to lie within the LISA sensitivity range.
Finally I will consider a scenario with feeble coupling between the dark and Standard
Model sector, allowing the temperatures of the two sectors to evolve independently during
the phase transition.
