Scientific paper

We present an analysis of the properties of HI selected galaxies that fall within both the HI Parkes All Sky Survey (HIPASS) and the Sloan Digital Sky Survey (SDSS). By comparing optical properties derived from SDSS with the HI properties from HIPASS, we are able to observe relationships between the cool gas and the stellar populations. We investigate how various physical parameters such as color, morphology, gas fraction, baryonic mass, dynamical mass, and surface brightness correlate with each other. This provides an important sample that can be used to study the factors that play a role in star formation efficiency. This study also allows us to compare the differences between HI and optically selected samples.
