Kristjan Muursepp
Description
In this talk I will discuss a recent work studying the viability of first order phase transitions and the detectability of the associated gravitational waves in a minimal KSZV axion model, which is extended with a single heavy degree of freedom. I will delineate the parameter space in which the phase transition accompanied by obersevable gravitational wave signal for ET or CE can take place and elaborate on new avenues in which the heavy degree of freedom can appear as a valid DM candidate, or affect the reheating of the plasma after the phase transition has completed.
