Watch an astrophysics seminar exploring the groundbreaking developments in pulsar timing array (PTA) experiments and their role in detecting gravitational waves. Learn how multiple PTA collaborations have discovered evidence for a stochastic gravitational wave background (SGWB), primarily generated by supermassive black hole binary systems. Delve into advanced analysis techniques for characterizing SGWB signals and testing general relativity, while discovering how pulsar timing data can be utilized to search for metric perturbations caused by ultralight dark matter within the Galaxy. Presented by Kimberly Boddy from The University of Texas at Austin at the Institute for Advanced Study, this 56-minute lecture offers cutting-edge insights into the intersection of gravitational wave astronomy and dark matter research.
