Description

We investigate the effects of change in temperature of thermal bath via non-adiabatic conditions on the phase transition and it's gravitational wave signature. Our preliminary results show that it is possible to get gravitational waves with shifted frequency due to the thermal kick to the bath in the early universe. This is a novel result and is ubiquitous in scenarios with non-instantaneos reheating, perturbation reentry leading to PBH formation and so on.
