Searching for Dark Matter and Dark Sector Particles Using Gravitational Waves

Explore a 41-minute lecture from the International Centre for Theoretical Sciences that delves into the search for dark matter and dark sector particles through gravitational wave detection. Learn how the experimental detection of gravitational waves from merging black holes and neutron stars opens new possibilities for investigating physics beyond the Standard Model. Understand the various sources of gravitational waves, including tensor perturbations during inflation, Primordial Black Holes formation, first-order Phase Transitions, and topological defects like cosmic strings. Discover how the detection of Stochastic Gravitational Wave Background (SGWB) by collaborations like NANO-Grav and InPTA provides evidence for probing high-scale physics that may be inaccessible through conventional experiments. Part of a comprehensive program on cosmic sources of Gravitational Waves, this lecture connects particle physics, cosmology, and gravitational wave research to explore fundamental questions about dark matter and the universe's composition.
