Abstract
In this paper, the authors discuss a new source of gravitational waves from first order phase transitions. The collision of bubbles in the new phase can efficiently produce particles that couple to the background field undergoing the transition, transferring a significant amount of the released vacuum energy into particle populations that long outlive the bubbles and provide a novel source of gravitational waves.
