Explore the fascinating world of stochastic background searches in gravitational wave experiments through this 50-minute lecture by Arianna Renzini from the California Institute of Technology. Delve into the concept of the stochastic gravitational wave background (SGWB), understanding how unresolved signals collectively form a background noise in gravitational wave detectors. Learn about various search methods employed in gravitational wave experiments, with a focus on ground-based networks. Discover the latest results from the LVK collaboration searches and gain insights into the estimated time-to-detection. Examine the potential for detection with LISA, the future space-borne gravitational wave observatory. Covering topics such as background characteristics, detection methods, cross-correlation statistics, and anisotropic searches, this comprehensive talk provides a thorough overview of current research and future prospects in the field of stochastic background searches in gravitational wave astronomy.
