Seeing the Invisible: Black Hole Superradiance and Gravitational Wave Sources

Explore a 26-minute lecture from the International Centre for Theoretical Sciences that delves into black hole superradiance and gravitational waves as part of the "Hearing beyond the standard model with cosmic sources of Gravitational Waves" program. Learn about the groundbreaking experimental detection of gravitational waves from merging black holes and neutron stars, and discover how these phenomena can probe physics beyond the Standard Model. Understand various sources of gravitational waves including inflation-related tensor perturbations, Primordial Black Holes (PBH), cosmological first-order Phase Transitions, and topological defects like cosmic strings. Examine the significance of recent Stochastic Gravitational Wave Background (SGWB) detection evidence by NANO-Grav, InPTA, and other PTA collaborations based on 15 years of observational data. Gain insights into how gravitational wave signals may reveal modifications to general relativity and their implications for high-scale physics that cannot be studied through conventional terrestrial experiments.
