摘要:

我们提出了最终的斯隆数字巡天IV(SDSS-IV)类星体目录从数据发布16的扩展重子振荡光谱调查(eBOSS)。该目录包括迄今为止光谱确认的类星体的最大选择。完整的星表包括两个子星表:一个是包含1,440,615个观测数据的所有SDSS-IV/eBOSS类星体的“超集”,另一个是包含750,414个类星体的类星体目录,其中包括225,082个首次出现在SDSS数据发布中的新类星体,以及来自SDSS-I/II/III的已知类星体。我们提供了这些类星体的自动识别和红移信息,以及320,161个光谱的目视检查数据。只有类星体的星表估计有99.8%是完整的,只有0.3%到1.3%的污染。通过主成分分析和发射谱线得到的红移补充了自动和目视检查的红移。我们包括H $α$、H $β$、Mg II、C III]、C IV和Ly $α$的发射线红移。识别和自动算法生成的关键特征,为99,856宽吸收线类星体和35,686阻尼莱曼阿尔法类星体。除了SDSS光度数据,我们还提供了来自GALEX,UKIDSS,WISE,FIRST,ROSAT/2 RXS,XMM-牛顿和盖亚的类星体的多波长数据。这些类星体的校准数字光谱可以从SDSS科学档案服务器获得。

英文摘要:

We present the final Sloan Digital Sky Survey IV (SDSS-IV) quasar catalog from Data Release 16 of the extended Baryon Oscillation Spectroscopic Survey (eBOSS). This catalog comprises the largest selection of spectroscopically confirmed quasars to date. The full catalog includes two sub-catalogs: a "superset" of all SDSS-IV/eBOSS objects targeted as quasars containing 1,440,615 observations and a quasar-only catalog containing 750,414 quasars, including 225,082 new quasars appearing in an SDSS data release for the first time, as well as known quasars from SDSS-I/II/III. We present automated identification and redshift information for these quasars alongside data from visual inspections for 320,161 spectra. The quasar-only catalog is estimated to be 99.8% complete with 0.3% to 1.3% contamination. Automated and visual inspection redshifts are supplemented by redshifts derived via principal component analysis and emission lines. We include emission line redshifts for H$α$, H$β$, Mg II, C III], C IV, and Ly$α$. Identification and key characteristics generated by automated algorithms are presented for 99,856 Broad Absorption Line quasars and 35,686 Damped Lyman Alpha quasars. In addition to SDSS photometric data, we also present multi-wavelength data for quasars from GALEX, UKIDSS, WISE, FIRST, ROSAT/2RXS, XMM-Newton, and Gaia. Calibrated digital optical spectra for these quasars can be obtained from the SDSS Science Archive Server.
