First-order phase transitions in the early Universe are a well-motivated source of gravitational
waves (GWs). In this talk, I will discuss a previously overlooked GW production mechanism:
gravitational transition radiation, arising from graviton emission by particles whose mass changes
as they pass through expanding bubble walls. The resulting spectrum features a distinctive shape with a...
