Learn about gravitational waves generated during cosmological phase transitions in this advanced physics lecture from the "Hearing beyond the standard model with cosmic sources of Gravitational Waves" program. Explore how the universe's transition from false vacuum to true vacuum creates detectable Stochastic Gravitational Wave Background (SGWB) signals through bubble nucleation, growth, and merger processes. Delve into fundamental physics beyond the Standard Model (BSM) of particle physics and cosmology, connecting theoretical concepts with recent observations from NANO-Grav, InPTA, and other Pulsar Timing Array collaborations. Part of a comprehensive workshop bringing together experts in particle physics, cosmology, and gravitational waves to discuss high-scale physics phenomena and their detection through gravitational wave astronomy.
