Gas and Stars in an HI-Selected Galaxy Sample

Abstract

We present the results of a J-band study of the HI-selected Arecibo Dual-Beam Survey and Arecibo Slice Survey galaxy samples using the 2 Micron All-Sky Survey data. We find that these galaxies span a wide range of stellar and gas properties. However, despite the diversity within the samples, we find a very tight correlation between luminosity and size in the J-band, similar to that we previously found (Rosenberg & Schneider 2003) between the HI mass and size. We also find that the correlation between the baryonic mass and the J-band diameter is even tighter than between the baryonic mass and the rotational velocity.
