Primordial Black Holes from Supercooled Phase Transitions in Early Universe Cosmology

Explore a 47-minute lecture from the International Centre for Theoretical Sciences' program on cosmic gravitational wave sources that delves into Primordial Black Holes formed during supercooled phase transitions. Learn about the intersection of gravitational wave physics and beyond Standard Model phenomena, including the formation mechanisms of Primordial Black Holes (PBH) during cosmic phase transitions. Understand how these astronomical phenomena contribute to the Stochastic Gravitational Wave Background (SGWB) and their significance in probing high-energy physics beyond current experimental capabilities. Part of a comprehensive workshop bringing together experts in particle physics, cosmology, and gravitational waves, this lecture connects to recent discoveries by NANO-Grav, InPTA, and other Pulsar Timing Array collaborations that have provided the first evidence of SGWB detection based on 15 years of observational data.
