Metallicities of GRB, DLA, and Ly{alpha} galaxies

We test the hypothesis that the host galaxies of long-duration gamma-ray bursts (GRBs) as well as quasar-selected damped Ly{alpha} (DLA) systems are drawn from the population of...我们验证了下述假说：长伽马射线暴（long-duration gamma-ray bursts, GRBs）的宿主星系，以及类星体选择的阻尼莱曼α（damped Lyα, DLA）系统，均来自于……的星系族群。
