Description
In this talk, I first introduce the hydrodynamic sound-shell model for gravitational waves from sound waves of first-order phase transitions, then we investigate the primordial black hole formations from the delayed-decay regions of first-order phase transitions, next we study the scalar-induced gravitational waves with non-Gaussianity up to all orders, and finally we propose sound-wave gravitational waves from primordial gravitational instability and its relation to the scalar-induced gravitational waves.
