Abstract:
We present the largest catalogue to date of optical counterparts for H
i radio-selected galaxies, HOPCAT. Of the 4315 H i radio-detected
sources from the HI Parkes All Sky Survey (HIPASS) catalogue, we find
optical counterparts for 3618 (84 per cent) galaxies. Of these, 1798
(42 per cent) have confirmed optical velocities and 848 (20 per cent)
are single matches without confirmed velocities. Some galaxy matches
are members of galaxy groups. From these multiple galaxy matches, 714
(16 per cent) have confirmed optical velocities and a further 258 (6
per cent) galaxies are without confirmed velocities. For 481 (11 per
cent), multiple galaxies are present but no single optical counterpart
can be chosen and 216 (5 per cent) have no obvious optical galaxy
present. Most of these "blank fields" are in crowded fields along
the Galactic plane or have high extinctions.
Isolated "dark galaxy" candidates are investigated using an
extinction cut of ABj<1mag and the blank-fields category. Of the
3692 galaxies with an A+Bj_ extinction <1mag, only 13 are also
blank fields. Of these, 12 are eliminated either with follow-up Parkes
observations or are in crowded fields. The remaining one has a low
surface brightness optical counterpart. Hence, no isolated optically
dark galaxies have been found within the limits of the HIPASS survey.
