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☉/L☉. 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.
