Metal-strong damped Ly{alpha} systems

We have identified a metal-strong [logN(Zn+)>=13.15 or logN(Si^+^)>=15.95] damped Ly{alpha} (MSDLA) population from an automated quasar (QSO) absorber search in the Sloan...我们从斯隆（Sloan）巡天的自动化类星体（quasar, QSO）吸收体搜寻工作中，识别出一类强金属丰度阻尼莱曼α（metal-strong damped Lyα, MSDLA）天体族群，其柱密度对数满足条件：logN(Zn⁺)≥13.15 或 logN(Si⁺)≥15.95。
