The Local Volume HI Survey (LVHIS)

HIPASS J1132-32

HIPASS J1132-32 is a dwarf irregular galaxy with an HI systemic velocity of ~680 km/s, originally discovered in HIPASS (Meyer et al. 2004). Our low-resolution ATCA data show an unresolved HI source, centered at α,δ(J2000) = 11:33:10.6, -32:57:45.2. It coincides with a compact blue dwarf galaxy (PGC 683190) that shows a faint extension to the west. No GALEX UV images are available. Higher resolution ATCA data reveal a marginally resolved HI source, matching the shape of the stellar body. Doyle et al. (2005) give optical magnitudes of BJ, R, and I = 16.28, 16.17, and 17.22 mag. Its nearest neighbours are HIPASS J1131-31 (80 arcmin), NGC 3621 (188 arcmin), and ESO 379-G007 (273 arcmin); projected distances are given in brackets. Based on its likely association with NGC 3621 (HIPASS J1118-32) we assign the same distance, ie. Dmem = 6.7 Mpc. We measure ATCA FHI = 1.4 Jy km/s, which corresponds to MHI = 1.5 × 107 M.
