Optical Identifications of 230 HIPASS Radio Sources

Abstract

We present the coordinates, apparent magnitudes, and morphological types for 230 galaxies presumably identified with HIPASS (HI Parkes All-Sky Survey) sources. The new optical counterparts of the HIPASS sources follow the well-known statistical relationships between the hydrogen mass, luminosity, and type of galaxies. Low-surface-brightness galaxies constitute a significant fraction among these objects. The median value of the hydrogen mass-to-luminosity ratio for them is a factor of 2 or 3 higher than that for bright HIPASS galaxies, reaching $1.7M_{\odot }/L_{\odot }$. A number of our objects are located near the boundary $\log (M_{HI}/L_B)=0.2(M_B+20)$ that defines the zone of gravitational stability of disk galaxies against large-scale star formation.
