A SURVEY of LUMINOUS HIGH-REDSHIFT QUASARS with SDSS and WISE. I. TARGET SELECTION and OPTICAL SPECTROSCOPY
High-redshift quasars are important tracers of structure and evolution in the early universe. However, they are very rare and difficult to find when using color selection because of contamination from late-type dwarfs. High-redshift quasar surveys based on only optical colors suffer from incompleteness and low identification efficiency, especially at $z\gtrsim 4.5$. We have developed a new method to select $4.7\lesssim z\lesssim 5.4$ quasars with both high efficiency and completeness by...[Show more]
