| 摘 要： | 基于斯隆数字化巡天(Sloan Digital Sky Survey,SDSS)第12期数据(data release 12,DR12)的光谱,分析引力透镜类星体SDSS J1001+5027的A, B两个像的光谱。两个像光谱的红移分别为1.84132±0.00024和1.84545±0.00012,透镜天体红移约为0.415。通过证认可靠的CⅣλλ1548, 1551或Mg Ⅱλλ2796, 2803窄吸收双线的方法,证认出A, B两个像的光谱中红移分别为1.60677±0.00012, 0.87140±0.00007和0.41455±0.00006的3个吸收系统。从3个吸收系统共证认出27条窄吸收线。测量27条窄吸收线的等值宽度,再通过分析、比较3个吸收系统在A, B两个像光谱中吸收线的数量及等值宽度的差异,给出了3个吸收系统在引力透镜类星体SDSS J1001+5027视线方向可能的分布示意图。

| Abstract: | The spectra of the two images of the gravitational lensing quasar SDSS J1001+5027 A and B are analyzed based on the spectra of the Data Release 12(DR12)of Sloan Digital Sky Survey(SDSS).The redshifts of the two images are 1.84132±0.00024 and 1.84545±0.00012 respectively,and the redshift of the lensing galaxy is about 0.415.By identifying the CⅣλλ1548,1551 or the MgⅡλλ2796,1551 double narrow absorption lines,the red shifts of A and B images were identified as three absorption systems of 1.60677±0.00012,0.87140±0.00007 and 0.41455±0.00006.Twenty-seven narrow absorption lines were identified by three absorption systems.The equivalent width values of the twenty-seven narrow absorption lines were measured.The differences of the numbers and equivalent widths of the absorption lines in the A and B image spectra of the three absorption systems were analyzed and compared.The possible distribution of three absorption systems in the line of sight direction of gravitational lensing quasar SDSS J1001+5027 is given. |
