Intensity Interferometry for Sub-Microarcsecond Resolution in AGN Observations

Explore the groundbreaking technique of intensity interferometry in this astrophysics seminar presented by Neal Dalal from the Perimeter Institute. Delve into the Hanbury Brown and Twiss (HBT) method, which achieves sub-microarcsecond angular resolution using standard ground-based optical telescopes observing visible light. Learn how this technique is particularly effective for compact, bright sources, with a focus on its applications to active galactic nuclei (AGN). Discover the potential of intensity interferometry observations in measuring the Hubble constant H0 and investigating the innermost structure of AGN accretion disks. Gain insights into cutting-edge astrophysical research and its implications for our understanding of supermassive black holes and the universe at large.
