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☉.
