Xiaohui Fan is a Regents Professor of Astronomy at the University of Arizona and an astronomer at Steward Observatory. His research focuses on observational cosmology, particularly on understanding the formation of the first luminous objects, reionization of the Universe, and the co-evolution of black holes and galaxies in the early universe.
- Key projects: "MAMMOTH" survey of massive large-scale structures and protoclusters
- Techniques: Pioneering searches for distant quasars at redshift z>6
- Major findings: Discovery of supermassive black holes within one billion years after the Big Bang
Current work involves quasar surveys at z>7 using near-IR data and studying reionization-era galaxies with facilities like ALMA, HST, LBT, and JWST. His research highlights the rapid increase in cold atomic gas at z~6, marking the end of the cosmic dark ages.
