Gravitational waves from bubble collisions in first order phase transitions

Jul 13, 2021, 4:50 PM


Marek Lewicki (University of Warsaw)


We will discuss energy budget of first order phase transitions and identify models capable of supporting extreme supercooling necessary to feature bubble collisions as the main source of gravitational waves. We will also review new semi-analytical calculation of the spectrum appropriate in such strong transitions.
