Extragalactic astronomy and observational cosmology, high-redshift quasars and supermassive black holes, high-redshift galaxies, cosmic reionization"Linhua Jiang is interested in the distant universe. His main research fields include the following:*) Large-area optical and near-IR survey data to search for quasars at high redshift (mainly at redshifts close to or higher than 6)*) Large ground-based telescopes to study the physical properties of high-redshift quasars and their implications for cosmic reionization*) Deep fields to search for high-redshift (again redshifts 6 or higher) galaxies
