Explore the cutting-edge field of gravitational-wave astronomy in this comprehensive astrophysics seminar that examines how black hole binaries form and merge. Learn the fundamental principles of gravitational-wave detection using LIGO–Virgo–KAGRA interferometers and discover how over 200 detected signals from merging black hole binaries are revolutionizing our understanding of these cosmic phenomena. Delve into the three-pronged observational approach that involves searching for gravitational-wave signals in noisy data, estimating crucial source parameters like masses and spins, and comparing observed distributions with theoretical formation models. Examine recent advancements in sensitivity improvements achieved through modeling additional harmonics beyond the dominant quadrupole, and understand the physical heuristics that help disentangle complex posterior distributions for more efficient parameter estimation. Investigate applications to simulation-based inference and discover how individual observations are systematically combined while accounting for selection effects, measurement uncertainty, and statistical significance. Gain insights into the latest observational results and their implications for understanding the leading formation channels of compact binary mergers, providing a comprehensive view of how gravitational-wave astronomy is unveiling the mysteries of black hole binary origins.
