Abstract:
Advancements in gravitational wave detection have opened a new window into the very early history of the universe and the corresponding models of fundamental physics. These observations offer crucial insights into key issues such as symmetry breaking, gravitational theories, and the origin of dark matter. This talk will briefly review and categorize the primary sources of gravitational waves, including primordial scalar perturbations, topological defects, preheating, and first-order phase transitions. We will discuss how the energy spectrum, anisotropies of gravitational waves, as well as curvature perturbations and dark matter associated to these sources, can provide powerful probes or constraints on fundamental physics and cosmic evolution.
