Searching in HI for Massive Low Surface Brightness Galaxies: II. Completing the UGC Sample
AI总结：
该研究完成UGC样本的HI搜寻，用绿岸望远镜观测35个LSB星系，探测到19个，还补充了5个偶然探测到的星系HI数据，丰富了LSB星系的相关样本。
AI中文摘要：
尽管低表面亮度（LSB）星系的研究日益深入，但其属性范围和演化历史仍存在相当大的不确定性。LSB星系在星系形成与演化中呈现出极具吸引力的极端情况，为检验星系形成与演化理论提供了绝佳的测试对象。此前，本团队已成功测量350个LSB星系的氢原子（HI）气体及动力学质量属性，大幅增加了已知极端LSB星系（如大质量、富气体等）的数量。本文报告了100米口径罗伯特·C·伯德绿岸望远镜（Robert C. Byrd Green Bank Telescope）对另外35个LSB星系的21厘米HI谱线观测结果，其中仅2个星系有已发表数据；在这35个星系中，19个被成功探测到。本文还包含5个额外星系的HI信息，这些星系是在空白天区或其他速度处偶然探测到的，此前均无已发表的HI结果。
英文摘要：
Although Low Surface Brightness (LSB) galaxies are increasingly well studied, considerable uncertainty still exists as to both their range in properties and their evolutionary history. LSB galaxies provide a fascinating extreme in galaxy formation and evolution, allowing excellent tests of galaxy formation and evolution theories. Previously, our group successfully measured the HI gas and dynamical mass properties of 350 LSB galaxies, significantly increasing the number of known extreme LSB galaxies (massive, gas rich, etc.) in the process. Here we oresent 100-m Robert C. Byrd Green Bank Telescope 21-cm HI line observations of a further 35 LBG galaxies, only two of which have previously published data. Of the 35, 19 were detected. This paper also includes the HI information for five additional galaxies detected accidentally (in the blank sky region or at alternative velocities), none of which has previously published HI results.
