Gas and stars in an HI-selected galaxy sample

We present the results of a J-band study of the H I-selected Arecibo Dual-Beam Survey and Arecibo Slice Survey galaxy samples using Two 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 found in a previous paper by Rosenberg W Schneider between the H I mass and size. We also find that the correlation between the baryonic mass and the J-band diameter is even tighter than that between the baryonic mass and the rotational velocity.
