We present the HIPASS Bright Galaxy Catalog (BGC) which contains the 1000
HI-brightest galaxies in the southern sky as obtained from the HI Parkes
All-Sky Survey (HIPASS). The selection of the brightest sources is based on
their HI peak flux density (Speak > 116 mJy) as measured from the spatially
integrated HIPASS spectrum. The derived HI masses range from about 10^7 to
4 x 10^10 Msun. While the BGC (z < 0.03) is complete in Speak, only a subset
of about 500 sources can be considered complete in integrated HI flux density
(FHI > 25 Jy km/s).
The HIPASS BGC contains a total of 158 new redshifts. These belong to 91 new sources for which no optical or infrared counterparts have previously been cataloged, an additional 51 galaxies for which no redshifts were previously known, and 16 galaxies for which the cataloged optical velocities disagree. Of the 91 newly catalogued BGC sources, only four are definite HI clouds: while three are likely Magellanic debris with velocities around 400 km/s, one is a tidal cloud associated with the NGC 2442 galaxy group. The remaining 87
HIPASS provides a clear view of the local large-scale structure. The dominant features in the sky distribution of the BGC are the Supergalactic Plane and the Local Void. In addition, one can clearly see the Centaurus Wall which connects via the Hydra and Antlia clusters to the Puppis filament. Some previously hardly noticed galaxy groups stand out quite distinctively in the HI sky distribution. Several new structures are seen for the first time, not only behind the Milky Way.
