摘要:

我们介绍了斯隆数字巡天III重子振荡光谱巡天(BOSS)的类星体数据发布9(DR 9 Q)目录。该目录包括在调查期间作为类星体候选者的所有BOSS对象,通过目视检查光谱学确认为类星体,亮度Mi[z=2]<-20.5(在H 0 = 70 km/s/Mpc的$Λ$ CDM宇宙学中,$Ω_{\rm M}$ = 0.3,且$Ω_Λ$ = 0.7),并且显示至少一条半峰全宽(FWHM)大于500 km/s的发射谱线,或者如果不是,则具有感兴趣的/复杂的吸收特征。它还包括BOSS重新观测到的已知类星体(主要来自SDSS-I和II)。该目录包含87,822个类星体(78,086个是新发现的),在3,275 deg $^{2}$上检测到,具有鲁棒的识别和红移,通过从SDSS-DR 7的8,632个光谱的训练集新导出的主成分本征光谱的组合来测量。具有$z>2.15$的类星体的数量(61,931)是之前已知的z>2.15类星体数量的2.8倍。提供了最强发射线(CIV、CIII]、MgII)的红移和FWHM。该目录识别了7,533个宽吸收线类星体并给出了它们的特征。对于每一个对象的目录提供了五个波段(u,g,r,i,z)CCD为基础的测光与典型的精度为0.03等,和信息的形态和选择方法。该目录还包含X射线,紫外线,近红外线和无线电发射性质的类星体,如果可用的话,从其他大面积的调查。

英文摘要:

We present the Data Release 9 Quasar (DR9Q) catalog from the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey III. The catalog includes all BOSS objects that were targeted as quasar candidates during the survey, are spectrocopically confirmed as quasars via visual inspection, have luminosities Mi[z=2]<-20.5 (in a $Λ$CDM cosmology with H0 = 70 km/s/Mpc, $Ω_{\rm M}$ = 0.3, and $Ω_Λ$ = 0.7) and either display at least one emission line with full width at half maximum (FWHM) larger than 500 km/s or, if not, have interesting/complex absorption features. It includes as well, known quasars (mostly from SDSS-I and II) that were reobserved by BOSS. This catalog contains 87,822 quasars (78,086 are new discoveries) detected over 3,275 deg$^{2}$ with robust identification and redshift measured by a combination of principal component eigenspectra newly derived from a training set of 8,632 spectra from SDSS-DR7. The number of quasars with $z>2.15$ (61,931) is ~2.8 times larger than the number of z>2.15 quasars previously known. Redshifts and FWHMs are provided for the strongest emission lines (CIV, CIII], MgII). The catalog identifies 7,533 broad absorption line quasars and gives their characteristics. For each object the catalog presents five-band (u,g,r,i,z) CCD-based photometry with typical accuracy of 0.03 mag, and information on the morphology and selection method. The catalog also contains X-ray, ultraviolet, near-infrared, and radio emission properties of the quasars, when available, from other large-area surveys.
