About
Hugh C. Harris is a leading figure in observational astrophysics, specializing in gravitational lensing, quasar accretion disk physics, and precision astrometry. His most impactful work, the 2013 multiwavelength microlensing analysis of the lensed quasar SBS 0909+532 (38 citations), revolutionized our understanding of quasar structure by measuring both the time delay between lensed images and the accretion disk size. This study, combining data from the U.S. Naval Observatory and the Liverpool Robotic Telescope, demonstrated how microlensing can probe sub-parsec scales in distant quasars, providing direct constraints on accretion disk models. Harris also spearheaded the U.S. Naval Observatory Robotic Astrometric Telescope 1st Catalog (URAT1, 2015), a foundational astrometric dataset that has enabled precise positional measurements for millions of celestial objects. His work bridges the gap between high-precision astrometry and time-domain astrophysics, offering critical tools for studying dark matter distribution and the geometry of the universe. With his deep expertise in robotic telescope operations and data analysis, Harris continues to shape how researchers extract cosmological information from gravitational lensing systems.
