MacQueen , Lawrence W. Ramsey , et al. ( Penn State, Princeton, IAS, Texas | | Abstract: | We report the discovery of 27 quasars with redshifts between 3.58 and 4.49. The objects were identified as high-redshift candidates based on their colors in Sloan Digital Sky Survey commissioning data. The redshifts were confirmed with low resolution spectra obtained at the Hobby-Eberly Telescope. The quasars’ $i^*$ magnitudes range from 18.55 to 20.97. Nearly 60% of the quasar candidates observed are confirmed spectroscopically as quasars. Two of the objects are Broad Absorption Line quasars, and several other quasars appear to have narrow associated absorption features. | | Source: | arXiv, astro-ph/0012083 | | Services: | Forum | Review | PDF | Favorites | |
