Watch a detailed lecture exploring gravitational waves from the "Hearing beyond the standard model with cosmic sources of Gravitational Waves" program at the International Centre for Theoretical Sciences. Delve into the physics of primary and scalar-induced secondary gravitational waves, examining their significance in understanding fundamental physics beyond the Standard Model. Learn about various sources of gravitational waves, from astrophysical mergers of black holes and neutron stars to cosmological phenomena like inflation, primordial black holes, and phase transitions. Explore how stochastic gravitational wave background signals can provide insights into high-scale physics that may be unreachable through conventional experiments. Understand recent developments including the NANO-Grav and InPTA collaborations' first evidence of stochastic gravitational wave background detection based on 15 years of observational data.
