Gravitational Wave Tails from Soft Theorem - Lecture 2

Explore gravitational wave physics in this advanced lecture focusing on gravitational wave tails from soft theorem, delivered by renowned physicist Ashoke Sen at the International Centre for Theoretical Sciences. Part of a comprehensive program on cosmic sources of gravitational waves, delve into fundamental physics beyond the Standard Model through the lens of gravitational wave detection. Learn about various sources of gravitational waves, from astrophysical mergers of black holes and neutron stars to cosmological phenomena like inflation, primordial black holes, phase transitions, and topological defects. Understand how the detection of Stochastic Gravitational Wave Background (SGWB) signals by collaborations like NANO-Grav and InPTA opens new possibilities for probing high-scale physics that may be inaccessible through conventional experiments. Examine the implications of gravitational wave detection for potential modifications to general relativity and its significance in advancing our understanding of fundamental physics and cosmology.
