ALFALFA in the Leo Region: Looking for Missing Satellites in HI
摘要：
在狮子座区域的20 Mpc内有两个邻近的星系群，这使得我们可以对低质量星系进行详细的研究。利用ALGOFA的盲测资料，编制了狮子座HI谱线（9 h36 m < RA <11 h36 m，+8deg < dec < +16deg）的探测目录。更敏感的单像素阿雷西博观测目标是Karachentsev等人2004年（K 04）光学注意到的狮子座矮候选人，以确定组成员，并允许比较HI和光学选择的样本。本演示突出了两个样本之间的差异和重大贡献盲HI调查可以使失踪的卫星问题。
英文摘要：
The location of two nearby galaxy groups within ~20 Mpc in the Leo region allows for a detailed study of low-mass galaxies. A catalog of HI line detections in Leo (9h36m < RA <11h36m, +8deg < dec < +16deg) has been made from the blind HI survey ALFALFA. More sensitive single-pixel Arecibo observations targeted Leo dwarf candidates noted optically by Karachentsev et al 2004 (K04) to determine group members and allow for a comparison of HI and optically-selected samples. This presentation highlights the differences between the two samples and the significant contribution blind HI surveys can make to the missing satellites problem.
