To create nHz frequency signals, the vacuum transitions must be supercooled. These slow transitions struggle to complete due to the cosmic expansion of the universe. Even if the transition is complete, the wave frequencies can be shifted by nHz. Therefore, while nanohertz gravitational waves are cold, their origin is likely not very cold.
