Explore a 23-minute conference talk from the Workshop on Phase Transitions and Topological Defects in the Early Universe, where UC Berkeley researcher Soubhik Kumar delves into the anisotropies of stochastic gravitational wave backgrounds and their implications for understanding primordial fluctuations. Learn how cosmological phase transitions can serve as powerful probes of primordial non-Gaussianities, offering complementary insights to CMB and LSS searches. Discover strategies for extracting cosmological signals from astrophysical foregrounds, with specific applications to LISA, Taiji, and BBO detection systems.
