摘要:

The Sloan Digital Sky Survey has obtained images in five broad-band colors for several hundred square degrees. We present color-color diagrams for stellar objects, and demonstrate that quasars are easily distinguished from stars by their distinctive colors. Follow-up spectroscopy in less than ten nights of telescope time has yielded 22 new quasars, 9 of them atz>3.65,and one withz=4.75,the second highest-redshift quasar yet known. Roughly 80&percent; of the high-redshift quasar candidates selected by color indeed turn out to be high-redshift quasars. ©1999 American Institute of Physics.
