Searching in HI for Massive Low Surface Brightness Galaxies: II. Completing the UGC Sample

Abstract

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.
