Minimal Magnetogenesis, Primordial Black Holes and Secondary Gravitational Waves in the Early Universe

Explore a 52-minute lecture from the International Centre for Theoretical Sciences' program "Hearing beyond the standard model with cosmic sources of Gravitational Waves" that delves into magnetogenesis, primordial black holes, and their connections to gravitational wave physics. Learn about the experimental detection of gravitational waves from merging black holes and neutron stars, and understand how these observations can probe physics beyond the Standard Model. Examine various sources of gravitational waves including inflation-related tensor perturbations, stochastic gravitational wave backgrounds (SGWB), primordial black hole formation, first-order phase transitions, and topological defects. Discover the significance of recent findings from NANO-Grav, InPTA, and other Pulsar Timing Array collaborations regarding the first evidence of SGWB detection, and understand how these observations contribute to our understanding of high-scale physics that may be unreachable through conventional experimental methods.
