HIPASS J1348-37

HIPASS J1348-37 is a dwarf irregular galaxy at α,δ(J2000) = 13:48:34.1, -37:58:08.0 as measured using our ATCA HI data. It was discovered by Banks et al. (1999) in a detailed HIPASS study of the Cen A Group. Its TRGB distance of 5.75 ± 0.66 Mpc (Karachentsev et al. 2007) places it beyond M 83 and more than 2 Mpc from Cen A. Its nearest neighbours are the dwarf galaxies ESO 383-G087 (HIPASS J1349-36), ESO 384-G016, ESO 325-G?011 (HIPASS J1345-41) and NGC 5408 (HIPASS J1403-41). Crnojevic et al. (2012) suggest that HIPASS J1348-37 may be a transition-type dwarf galaxy, given its absence of recent star formation. They derive a stellar mass of ~2 (±1) × 107 M. Our ATCA HI data show a barely resolved source, centred on the faint optical body. There is a hint of a north-south velocity gradient. We measure FHI = 1.6 Jy km/s, in agreement with HIPASS (Meyer et al. 2004), and derive an HI mass of at least 1.2 × 107 M.
