摘要:

基于斯隆数字化巡天(Sloan Digital Sky Survey, SDSS)第十二期发布(The Data Release 12, DR12)的光谱数据,我们从40个具有CIVλλ1548,1551窄吸收双线等值宽度变化的光谱中,搜寻到17个具有CIV mini-BAL的类星体,其中11个源在CIV窄发射线附近有CIV NAL。利用高斯函数分别对CIV mini-BAL、CIV NAL进行拟合,通过测量等值宽度值,我们得到17个CIV mini-BAL的静止坐标系等值宽度平均值是3.75 Å,11个CIV NAL的静止坐标系等值宽度平均值是1.25 Å。

Based on the spectral data of the 12th issue of The Data Release 12 (DR12) of Sloan Digital Sky Survey (SDSS), we have 40 spectra with CIVλλ1548,1551 narrow absorption double line equivalent width variation, 17 quasars with CIV mini-BAL were found, 11 of which had CIV NAL near the CIV narrow emission line. Using the Gaussian function to fit the CIV mini-BAL and CIV NAL respectively, by measuring the equivalent width value, we obtained that in quasar rest frame, the average width of the equivalent of the 17 CIV mini-BAL and 11 CIV NAL is 3.75 Å and 1.25 Å, respectively.
