The Extremely Luminous Quasar Survey in the SDSS Footprint. I. Infrared-based Candidate Selection
Studies of the most luminous quasars at high redshift directly probe the evolution of the most massive black holes in the early Universe and their connection to massive galaxy formation. However, extremely luminous quasars at high redshift are very rare objects. Only wide area surveys have a chance to constrain …
