HI in Local Supercluster dwarf galaxies

We have observed 71 dwarf galaxies of low surface brightness using the 100-m radio telescope at Effelsberg in a search for new members of 27 northern galaxy groups with...我们在搜寻27个北天星系群的新成员过程中，利用埃费尔斯贝格（Effelsberg）100米射电望远镜，观测到71个低表面亮度矮星系（low surface brightness dwarf galaxies）……
